Cystadenoma: A benign neoplasm derived from glandular epithelium, in which cystic accumulations of retained secretions are formed. In some instances, considerable portions of the neoplasm, or even the entire mass, may be cystic. (Stedman, 25th ed)Cystadenoma, Mucinous: A multilocular tumor with mucin secreting epithelium. They are most often found in the ovary, but are also found in the pancreas, appendix, and rarely, retroperitoneal and in the urinary bladder. They are considered to have low-grade malignant potential.Cystadenoma, Serous: A cystic tumor of the ovary, containing thin, clear, yellow serous fluid and varying amounts of solid tissue, with a malignant potential several times greater than that of mucinous cystadenoma (CYSTADENOMA, MUCINOUS). It can be unilocular, parvilocular, or multilocular. It is often bilateral and papillary. The cysts may vary greatly in size. (Dorland, 27th ed; from Hughes, Obstetric-Gynecologic Terminology, 1972)Cystadenoma, Papillary: A benign neoplasm of the ovary.Cystadenocarcinoma: A malignant neoplasm derived from glandular epithelium, in which cystic accumulations of retained secretions are formed. The neoplastic cells manifest varying degrees of anaplasia and invasiveness, and local extension and metastases occur. Cystadenocarcinomas develop frequently in the ovaries, where pseudomucinous and serous types are recognized. (Stedman, 25th ed)Appendiceal Neoplasms: Tumors or cancer of the APPENDIX.Mucocele: A retention cyst of the salivary gland, lacrimal sac, paranasal sinuses, appendix, or gallbladder. (Stedman, 26th ed)Biliary Tract Neoplasms: Tumors or cancer in the BILIARY TRACT including the BILE DUCTS and the GALLBLADDER.Bile Duct Neoplasms: Tumors or cancer of the BILE DUCTS.Appendix: A worm-like blind tube extension from the CECUM.Adenoma, Bile Duct: A benign tumor of the intrahepatic bile ducts.Cysts: Any fluid-filled closed cavity or sac that is lined by an EPITHELIUM. Cysts can be of normal, abnormal, non-neoplastic, or neoplastic tissues.Sertoli-Leydig Cell Tumor: A sex cord-gonadal stromal tumor consists of LEYDIG CELLS; SERTOLI CELLS; and FIBROBLASTS in varying proportions and degree of differentiation. Most such tumors produce ANDROGENS in the Leydig cells, formerly known as androblastoma or arrhenoblastoma. Androblastomas occur in the TESTIS or the OVARY causing precocious masculinization in the males, and defeminization, or virilization (VIRILISM) in the females. In some cases, the Sertoli cells produce ESTROGENS.Bile Ducts, Intrahepatic: Passages within the liver for the conveyance of bile. Includes right and left hepatic ducts even though these may join outside the liver to form the common hepatic duct.Pancreatic Neoplasms: Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).Adenolymphoma: A benign tumor characterized histologically by tall columnar epithelium within a lymphoid tissue stroma. It is usually found in the salivary glands, especially the parotid.Cystadenocarcinoma, Mucinous: A malignant cystic or semisolid tumor most often occurring in the ovary. Rarely, one is solid. This tumor may develop from a mucinous cystadenoma, or it may be malignant at the onset. The cysts are lined with tall columnar epithelial cells; in others, the epithelium consists of many layers of cells that have lost normal structure entirely. In the more undifferentiated tumors, one may see sheets and nests of tumor cells that have very little resemblance to the parent structure. (Hughes, Obstetric-Gynecologic Terminology, 1972, p184)Cecal Diseases: Pathological developments in the CECUM.Hepatic Duct, Common: Predominantly extrahepatic bile duct which is formed by the junction of the right and left hepatic ducts, which are predominantly intrahepatic, and, in turn, joins the cystic duct to form the common bile duct.Spermatocele: A cystic dilation of the EPIDIDYMIS, usually in the head portion (caput epididymis). The cyst fluid contains dead SPERMATOZOA and can be easily differentiated from TESTICULAR HYDROCELE and other testicular lesions.Endocrine Gland Neoplasms: Tumors or cancer of the ENDOCRINE GLANDS.Ovarian Neoplasms: Tumors or cancer of the OVARY. These neoplasms can be benign or malignant. They are classified according to the tissue of origin, such as the surface EPITHELIUM, the stromal endocrine cells, and the totipotent GERM CELLS.Aspermia: A condition characterized by the complete absence of SEMEN. This disorder should be differentiated from AZOOSPERMIA, absence of sperm in the semen.Pseudomyxoma Peritonei: A condition characterized by poorly-circumscribed gelatinous masses filled with malignant mucin-secreting cells. Forty-five percent of pseudomyxomas arise from the ovary, usually in a mucinous cystadenocarcinoma (CYSTADENOCARCINOMA, MUCINOUS), which has prognostic significance. Pseudomyxoma peritonei must be differentiated from mucinous spillage into the peritoneum by a benign mucocele of the appendix. (Segen, Dictionary of Modern Medicine, 1992)Salivary Gland Neoplasms: Tumors or cancer of the SALIVARY GLANDS.Pancreatic Cyst: A true cyst of the PANCREAS, distinguished from the much more common PANCREATIC PSEUDOCYST by possessing a lining of mucous EPITHELIUM. Pancreatic cysts are categorized as congenital, retention, neoplastic, parasitic, enterogenous, or dermoid. Congenital cysts occur more frequently as solitary cysts but may be multiple. Retention cysts are gross enlargements of PANCREATIC DUCTS secondary to ductal obstruction. (From Bockus Gastroenterology, 4th ed, p4145)Urologic Surgical Procedures, Male: Surgery performed on the male genitalia.Neoplasms, Multiple Primary: Two or more abnormal growths of tissue occurring simultaneously and presumed to be of separate origin. The neoplasms may be histologically the same or different, and may be found in the same or different sites.Retroperitoneal NeoplasmsSalivary Glands, Minor: Accessory salivary glands located in the lip, cheek, tongue, floor of mouth, palate and intramaxillary.Tomography, X-Ray Computed: Tomography using x-ray transmission and a computer algorithm to reconstruct the image.Pancreatic Pseudocyst: Cyst-like space not lined by EPITHELIUM and contained within the PANCREAS. Pancreatic pseudocysts account for most of the cystic collections in the pancreas and are often associated with chronic PANCREATITIS.Ovarian Cysts: General term for CYSTS and cystic diseases of the OVARY.Cholangiopancreatography, Magnetic Resonance: Non-invasive diagnostic technique for visualizing the PANCREATIC DUCTS and BILE DUCTS without the use of injected CONTRAST MEDIA or x-ray. MRI scans provide excellent sensitivity for duct dilatation, biliary stricture, and intraductal abnormalities.Pancreatic Diseases: Pathological processes of the PANCREAS.Bile Ducts, Extrahepatic: Passages external to the liver for the conveyance of bile. These include the COMMON BILE DUCT and the common hepatic duct (HEPATIC DUCT, COMMON).Appendectomy: Surgical removal of the vermiform appendix. (Dorland, 28th ed)Pancreatectomy: Surgical removal of the pancreas. (Dorland, 28th ed)Cystadenocarcinoma, Serous: A malignant cystic or semicystic neoplasm. It often occurs in the ovary and usually bilaterally. The external surface is usually covered with papillary excrescences. Microscopically, the papillary patterns are predominantly epithelial overgrowths with differentiated and undifferentiated papillary serous cystadenocarcinoma cells. Psammoma bodies may be present. The tumor generally adheres to surrounding structures and produces ascites. (From Hughes, Obstetric-Gynecologic Terminology, 1972, p185)Adenocarcinoma, Mucinous: An adenocarcinoma producing mucin in significant amounts. (From Dorland, 27th ed)Carcinoid Tumor: A usually small, slow-growing neoplasm composed of islands of rounded, oxyphilic, or spindle-shaped cells of medium size, with moderately small vesicular nuclei, and covered by intact mucosa with a yellow cut surface. The tumor can occur anywhere in the gastrointestinal tract (and in the lungs and other sites); approximately 90% arise in the appendix. It is now established that these tumors are of neuroendocrine origin and derive from a primitive stem cell.

An image is constructed through point-by-point scanning of the field in this manner. Light sources may be conventional or laser, and fluorescence or transmitted observations are possible.Cystoscopy: Endoscopic examination, therapy or surgery of the urinary bladder.Endosonography: Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.Research Support, U.S. Gov't, Non-P.H.S.Research Support, U.S. Gov't, P.H.S.Research Support, Non-U.S. Gov't

Overexpression of H-Ryk in mouse fibroblasts confers transforming ability in vitro and in vivo: correlation with up-regulation in epithelial ovarian cancer. (1/109)

Abnormalities in the function of receptor tyrosine kinases (RTKs) have been demonstrated to be important in the pathogenesis of cancer. H-Ryk, a new member of the RTK family, is an unusual RTK in that it is catalytically inactive because of amino acid substitutions of conserved residues in the catalytic domain. We show by immunohistochemistry that it is expressed in the epithelium, stroma, and blood vessels of normal tissues. Evaluation of a panel of 33 primary ovarian tumors (2 benign, 8 borderline, and 23 malignant) was performed. H-Ryk was overexpressed in borderline and malignant ovarian tumors. In serous and clear cell subtypes, there was increased expression in the epithelium, stroma, and blood vessels. Consistent with this observation, overexpression of H-Ryk in the mouse fibroblast cell line NIH3T3 induces anchorage-independent growth and tumorigenicity in nude mice. This implies that overexpression of the receptor can be transforming and may therefore be significant in the pathogenesis of ovarian cancer.  (+info)

Mucinous cystadenocarcinoma in combination with hemangiosarcoma in the ovary. (2/109)

The ovary is the sixth most frequent site of cancer in women in Denmark with an incidence of approximately 600 cases per year. Carcinomas predominate whereas sarcomas are rare. We describe a case of the combination mucinous cystadenocarcinoma and hemangiosarcoma in a 37-year old woman, who had a right-sited oophorectomy because of a cyst. Clinically there was no suspicion of malignancy. The macro- and microscopic findings are described as well as the immunohistochemical stainings performed to confirm the diagnosis. The case shows the importance of careful sampling at the macroscopic examination, especially from areas with a striking appearance.  (+info)

Clinical and pathologic correlation of 84 mucinous cystic neoplasms of the pancreas: can one reliably differentiate benign from malignant (or premalignant) neoplasms? (3/109)

OBJECTIVE: To determine whether the long-term behavior of cystic mucinous neoplasms of the pancreas could be predicted using a novel, precisely defined classification of benign mucinous cystadenomas, noninvasive proliferative cystic mucinous neoplasms, and invasive mucinous cystadenocarcinomas. The primary interest was to obtain long-term follow-up after complete resection to determine the recurrence rates based on this objective classification. BACKGROUND: Current understanding is that all cystic mucinous neoplasms of the pancreas are potentially malignant and that mucinous cystadenomas, when completely removed, are biologically benign. Cystadenocarcinomas are thought to be less aggressively malignant than ordinary ductal adenocarcinoma, but reported recurrence rates vary widely and are unpredictable. METHODS: All patients who underwent "curative" resection for cystic mucinous neoplasms at Mayo Clinic Rochester from 1940 to 1997 were identified. All available pathology slides, gross specimens, and clinical records were reviewed, eliminating patients with inadequate documentation. Neoplasms were reclassified as mucinous cystadenomas, noninvasive proliferative mucinous cystic neoplasms, or invasive cystadenocarcinomas based on specific histologic criteria. RESULTS: Of 84 patients (70 women, 14 men) with cystic mucinous neoplasms of the pancreas, 54 were classified as cystadenomas, 23 as noninvasive proliferative cystic mucinous neoplasms, and only 7 as cystadenocarcinomas. Recurrent disease developed in none of the 77 patients without invasion, but 5 of the 6 patients surviving resection for cystadenocarcinomas died of recurrent cystadenocarcinoma within 5 years. CONCLUSIONS: When the neoplasm is completely resected and subjected to adequate histopathologic examination based on these objective criteria, absence of tissue invasion predicts a curative operation and detailed follow-up may be unnecessary. In contrast, a histologic diagnosis of invasive cystadenocarcinoma portends a dismal prognosis, similar to that of typical ductal adenocarcinoma of the pancreas.  (+info)

Expression of a homeobox gene (SIX5) in borderline ovarian tumours. (4/109)

AIMS: To assess the expression of SIX5 (a homeobox gene) mRNA in surface coelomic epithelium, endocervical epithelium, Fallopian tube epithelium, and benign, borderline, and malignant epithelial ovarian tumours. METHODS: 10 normal premenopausal ovaries, 10 normal Fallopian tubes, 10 normal cervices, 10 normal postmenopausal ovaries, 10 benign epithelial ovarian tumours, 10 malignant epithelial ovarian tumours, and 40 borderline epithelial ovarian tumours were studied retrospectively. The tissues had been fixed in formalin and embedded in paraffin wax. The tumours had previously been typed into mucinous, serous, or mixed tumours and assigned to the borderline category according to the FIGO/WHO criteria. Expression was assessed by in situ binding of SIX5 specific sense and antisense riboprobes. Hybridization of the riboprobes was detected using a standard immunohistochemical technique and the results correlated with expression in the normal epithelium of the endocervix, Fallopian tube, surface coelomic epithelium, and ovarian tumours. RESULTS: Expression of SIX5 mRNA was demonstrated in normal Fallopian tube epithelium and normal endocervical epithelium. SIX5 mRNA was not detected in normal ovarian epithelial tissue at any of the times studied during the menstrual cycle. Expression of SIX5 was not shown in benign epithelial ovarian tumours or in any of the malignant epithelial ovarian tumours. In 31 of 37 borderline epithelial ovarian tumours (84%), SIX5 expression was found in the epithelial cells. CONCLUSIONS: SIX5 expression is present in the normal epithelium throughout most of the female reproductive tract, suggesting it may have a role in maintaining epithelial differentiation in these tissues. SIX5 expression appears to be restricted to borderline epithelial ovarian tumours and may be a marker of epithelial differentiation in these tumours; thus borderline ovarian tumours may not be part of a continuum of disease between benign and malignant epithelial ovarian tumours. Further investigation of expression of SIX5 may clarify the molecular processes that promote differentiation of the ovarian surface epithelium.  (+info)

The coexistence of low-grade mucinous neoplasms of the appendix and appendiceal diverticula: a possible role in the pathogenesis of pseudomyxoma peritonei. (5/109)

We examined 38 appendectomies with diagnoses of mucocele, diverticulum, or adenoma to study the coincidence of appendiceal diverticula and appendiceal low-grade mucinous neoplasms and to examine the possible role of diverticula in the pathogenesis of pseudomyxoma peritonei. Invasive adenocarcinomas and retention cysts were excluded (six cases). Cases were classified as adenomas or mucinous tumors of unknown malignant potential, with or without diverticula. Medical records were reviewed for multiple parameters, including presenting symptoms, presence of pseudomyxoma peritonei, and presence of associated malignancies. Binomial statistics were used to calculate the probability that the observed prevalence of low-grade mucinous neoplasms and diverticula together was significantly different from the expected prevalence of diverticula or low-grade mucinous neoplasms alone, using historical controls from the literature. Twenty-five percent of the total cases (8 of 32) contained both a low-grade mucinous neoplasm (7 cystadenomas and 1 mucinous tumor of unknown malignant potential) and a diverticulum. Thus, 8 of 19 low-grade mucinous neoplasms (42%) were associated with diverticula. Of the appendices with both low-grade mucinous neoplasms and diverticula, three contained dissecting acellular mucin within the appendiceal wall, four showed diverticular perforation, and one had pseudomyxoma peritonei associated with the ruptured diverticulum. A significant percentage (P < .001) of cases contained low-grade mucinous neoplasms and diverticula together. The case of coexistent low-grade mucinous neoplasm, diverticulum, and pseudomyxoma peritonei suggests that diverticula could play a role in the pathogenesis of pseudomyxoma peritonei. This could occur either by involvement of preexisting diverticula by the neoplasm or by distention of the appendiceal lumen by mucin, leading to increased intraluminal pressure and subsequent diverticulum formation at a weak area in the wall. Either mechanism might allow low-grade mucinous neoplasms to penetrate the appendiceal wall more easily.  (+info)

Clear cell carcinoma of the ovary arising in a mucinous cystadenoma. (6/109)

A 57 year old woman presented complaining of increasing abdominal swelling of six months duration. A mixed solid cystic left ovarian tumour measuring 24 cm in diameter was excised. Histology showed numerous cysts lined by benign mucinous epithelium blending imperceptibly into borderline clear cell and mucinous areas that in turn merged with an invasive clear cell carcinoma. To the best of our knowledge, this is the first reported case of clear cell carcinoma arising in a mucinous cystadenoma. The implications for the previously postulated pathogenesis of these tumours are discussed.  (+info)

Mucinous cystadenoma coexisting with stromal tumor with minor sex-cord elements of the ovary: a case report. (7/109)

Mucinous neoplasms occur rarely in association with cystic teratoma, Sertoli-Leydig cell tumor, granulosa cell tumor or carcinoid tumor. Several cases of an ovarian stromal tumor with minor sex-cord elements have been reported in the literatures. However, there has been no report about an ovarian mucinous neoplasm coexisting with a stromal tumor with sex-cord elements yet. We report a case of an ovarian neoplasm composed of both mucinous cystadenoma and stromal tumor with minor sex-cord elements in a 58-yr-old female. The ovary including the mass measured 5 cm in size. On section, it revealed an unilocular cyst (4.5 cm in diameter) filled with mucinous fluid. There was a round, yellow, solid nodule, 1.5 cm in diameter within the wall. Microscopically, the cyst was lined by a single layer of endocervical mucinous epithelium and the nodule was composed of spindle cells showing an intersecting and whorled arrangement. There were cell nests showing polygonal shape with abundant cytoplasm among the spindle cells. They showed immunoreactivity for inhibin and did not have any connection with the adjacent mucinous epithelium. Therefore, we interpret the mucinous cystadenoma as having arisen de novo.  (+info)

Expression of laminin-5-gamma-2 chain in intraductal papillary-mucinous and invasive ductal tumors of the pancreas. (8/109)

The laminin-5-gamma-2 chain is expressed in various invasive carcinoma cells. To clarify the relationship between laminin-5 expression and the development of intraductal papillary-mucinous tumors (IPMTs), we performed an immunohistochemical study of 26 IPMTs and 30 invasive ductal adenocarcinomas. Cases were classified into five groups: intraductal papillary-mucinous adenoma (Group A; n = 8), adenocarcinoma without invasion (Group B; n = 3), adenocarcinoma with minimal invasion (Group C; n = 5), adenocarcinoma with macroscopically evident invasion (Group D; n = 10), and invasive ductal adenocarcinoma (conventional type; Group E; n = 30). In the invasive components of Groups D and E, laminin-5 was expressed in 80% and 100% of cases, respectively. In the intraductal components of IPMTs, expression of laminin-5 was not seen in Groups A and B, whereas they were seen in one case in Group C (20%) and in seven in Group D (70%). Most of the staining patterns of the intraductal components were focal and scattered. Laminin-5-gamma-2 expression in the intraductal components of IPMTs tends to increase as tumors develop and may be a indicator of the potential invasiveness of the tumor cells.  (+info)

Mucinous cystadenoma is a type of cystic neoplasm. This type of tumor is usually benign when small but can grow and degenerate into a frank cancer. Most patients with these tumors are in their 5th and 6th decade and it is more common in women. Most of these tumors occur in the body and tail of the pancreas. As with serous cystadenomas they can usually be definitely diagnosed with modern diagnostic testing. When small (,3cm) and asymptomatic, most experts feel these lesions can be safely observed provided there is close surveillance with CT scans. If the lesion is ,3cm, causing symptoms or obstructing the pancreatic duct they should be surgically excised. Even if a cystadenocarcinoma is found, the prognosis is quite good if the tumor can be surgically removed.. ...

A mucocele of the appendix is a descriptive term that refers to dilation of a lumen because of accumulation of a large amount of mucin. It is a rare lesion in all resected appendiceal tumors. Schistosomiasis of the appendix is also a rare lesion and is observed in 0.4% of all appendectomies performed [7]. Simultaneous giant mucinous cystadenoma of the appendix and intestinal schistosomiasis is extremely rare. To our knowledge, this is the first case ever to be reported in the world.. The characteristic pathological tissue response of appendiceal schistosomiasis is believed to be a granulomatous inflammatory reaction to the schistosomal ova. There is formation of epithelioid cell granulomas, predominantly in the submucosa and serosa, which ultimately undergo fibrosis. The final pathologic examination of the present case revealed calcified Schistosome eggs within the mucosa, submucosa of the appendix, small intestine, colon, and lymph nodes. Considering that mucoceles are caused by mucus ...

TY - JOUR. T1 - Invasive cancer and survival of intraductal papillary mucinous tumors of the pancreas. AU - Raimondo, Massimo. AU - Tachibana, Issei. AU - Urrutia, Raul. AU - Burgart, Lawrence J.. AU - DiMagno, Eugene P.. PY - 2002/10/1. Y1 - 2002/10/1. N2 - OBJECTIVES: Intraductal papillary mucinous tumor (IPMT) is frequently associated with pancreatic cancer. We hypothesized that IPMT progresses to invasive cancer with K-ras mutations as an early event, and that invasive cancer affects survival. We compared survival after resection and determined whether K-ras mutations predicted survival in IPMT patients without or with invasive cancer. METHODS: Records of 47 patients with IPMT who were seen between 1983 and 1998 were reviewed retrospectively in 15 cases and prospectively in 32. All histological material was reviewed to confirm the diagnosis of IPMT and to assess invasion. Kaplan-Meier survival curves were analyzed by the log-rank test. The X2 test was used for differences in K-ras between ...
TY - JOUR. T1 - High yields of K-ras mutations in intraductal papillary mucinous tumors and invasive adenocarcinomas induced by N-nitroso(2-hydroxypropyl)(2-oxopropyl)amine in the pancreas of female Syrian hamsters. AU - Sugio, Kenji. AU - Gazdar, Adi F.. AU - Albores-Saavedra, Jorge. AU - Kokkinakis, Demetrius M.. PY - 1996. Y1 - 1996. N2 - Ductal adenocarcinoma, the most common form of pancreatic cancer in humans, is associated with activation of the K-ras oncogene in ~90% of cases. In contrast, K-ras mutations are found in ,50% of the relatively rare intraductal papillary mucinous tumor (IPMT), which arises in the main pancreatic ducts. Since both adenocarcinomas and IPMTs are believed to arise from ductal cells and progress through similar sequences of morphological changes (i.e. flat hyperplasia, papillary hyperplasia, atypia and carcinoma in situ), it is clear that such progression may not always necessitate activation of the ras oncogene. Experimentally ductal adenocarcinomas of the ...

Case presentation: A 68-year-old Italian man was admitted to our unit complaining of macrohematuria, rectorrhagia, and rectal tenesmus for about 2 months. A colonoscopy showed the presence of a rectal lesion at 11cm from the anal margin; multiple biopsies were performed and a diagnosis of moderately differentiated adenocarcinoma was made. Abdominal ultrasonography and total body computed tomography performed subsequently to stage the rectal cancer showed the presence of two round nodules, interpreted as swollen lymph nodes of neoplastic origin, at the anterior aspect of the iliopsoas muscle and a budding lesion affecting the bladder. The patient underwent transurethral biopsy of the lesion in the right retrotrigonal region; the diagnosis was grade II urothelial carcinoma. The patient underwent an open anterior rectal resection with loco-regional lymphadenectomy. An enlarged appendix and a voluminous whitish soft-tissue lesion requiring an appendicectomy were detected perioperatively. ...

Age over 70 (p = 0.031) and CA 19-9 over 300 U/mL (p = 0.015) were shown as significant predictors of malignancy. BMPCN with mural nodule (p = 0.002) and abrupt change of the bile duct (p = 0.027) was more likely in malignancy. Age over 70 (OR: 6.37, 95% CI: 1.15-35.2, p = 0.034), CA19-9 over 300 U/mL (OR: 3.97, 95% CI: 1.12-14.0, p = 0.032) and mural nodule over 20mm (OR: 10.32, 95% CI: 1.54-68.7, p = 0.016) were independent predictors of malignancy. The lesion that had more than 2 of 4 points (age over 70, CA19-9 over 300 U/mL, mural nodule over 20mm and abrupt change of the bile duct) had high accuracy for predicting malignancy (sensitivity: 84.2%, specificity: 83.3%, AUC = 0.867). ...

Pancreatic mucinous cystic neoplasm, also mucinous cystic neoplasm of the pancreas and mucinous cystic tumour, is a grouping of cystic neoplasms that arise from the pancreas. They may be benign, malignant or in between. The prognosis of this set of tumours is highly variable and dependent on the specific sub-classification (benign, borderline, malignant). Mucinous cystic neoplasms of the pancreas are defined by the World Health Organization (WHO) as cystic epithelial neoplasms that occur almost exclusively in women; do not communicate with the pancreatic ductal system and which are composed of columnar, mucin-producing epithelium, supported by ovarian-type stroma. This means that these tumors make mucin (a thick sticky fluid), they do not arise in the larger pancreatic ducts, and they have a peculiar supporting stroma (or support structure). Mucinous cystic neoplasms of the pancreas classified as benign, borderline, or malignant, based on histomorphological features which predict their ...

Histologically, cystoadenomas are characterised by the presence of cysts lined with mucinous cuboidal or columnar epithelium.6 An ovarian-type stroma is seen in 85% of cases and exclusively in females.4 A marsupial pseudocapsule separates the cystadenoma from the biliary epithelium.4 Elevated levels of CA 19-9 and/or CEA have been reported within the cysts themselves.1 2 4 11 12. Although the biliary cystadenoma is a benign entity, malignant transformation can occur, leading to cystadenocarcinoma.4 Sarcomatous transformation has also been described in one case.6 It has been suggested that cystadenocarcinomas arising from biliary cystadenomas with ovarian-type stroma have a relatively indolent course, whereas cystadenomas without ovarian-type stroma have a poorer prognosis.4. Most commonly, on radiologic imaging, these neoplasms appear as multi-loculated, multi-septated intrabiliary neoplasms. They are usually large at the time of presentation, with a mean tumour size of 15 centimetres.4 On CT, ...
A 53-yr-old woman with a history of hepatic cystadenoma 25 yr before presented with a simple hepatic cyst, which evolved over 9 yr into a complex cystadenoma with septations and internal bleeding. She was treated with a left hepatectomy. Review of the literature shows that hepatic cystadenomas, although rare, frequently can recur years later and have potential for malignant transformation. Histologic similarities of one variant with ovarian stroma raises interesting possibilities regarding the origin of these lesions. The best treatment results are obtained with radical excision ...

Symptoms. Mucinous Cystadenocarcinomas are more common in the body and tail of the pancreas. They can be more prominent then 10 centimeters. Guess with this kind of pancreatic cancer for the most part better. Pancreatoblastomas are uncommon (0.5 percent) exocrine tumors commonly found in children under 10 years of age, however it can happen all through lifetime. Pancreatoblastomas are recognized all the more regularly in guys and Asians. They show up as a group of cells among ordinary cells. Survival is superior to with adenocarcinoma.. Serous Cystadenomas are ordinarily kindhearted tumors. They have a wipe like improvement and can be cumbersome. They are loaded with watery fluid, while mucinous cystadenomas are loaded with a thicker sticky liquid. Serous cystadenomas comprise of single or different growths averaging 5-8 cm and upwards to 25 cm in breadth. Papillary Tumors are uncommon with an inclination for young ladies principally between 19 - 50 years of age. It is a huge round very much ...
Struma ovarii is a rare ovarian tumor defined by the presence of thyroid tissue comprising more than 50% of the overall mass. It most commonly occurs as part of a teratoma, but may occasionally be encountered with serous or mucinous cystadenomas.
There are many different types of ovarian cysts. The most common are physiological cysts, also known as "simple" or "functional" cysts, because they form as part of normal ovarian processes. There are two types of simple cysts: follicular cysts, which form when an ovarian follicle (egg sac) doesnt release its ovum (egg) and fills up with clear fluid; and luteal cysts, which form in ruptured follicles and are more likely to cause spotting, heavy bleeding or early/late periods. Both follicular and luteal cysts usually disppear on their own. With polycystic ovarian syndrome, lots of little cysts form all over the ovarys surface. The first signs of the condition include heavy bleeding and irregular periods and, over time, these cysts can affect fertility. This condition is generally treated hormonally. Other benign cysts include hormone-producing cysts, serous and mucinous cystadenomas, fibromas and Brenner tumours. Most of these should be surgically removed once discovered. In all cases, ...

Cystic neoplasms of the pancreas represent about 10% of all cysts of the pancreas and ~1% of all pancreatic neoplasms. Much has been learned about the natural history and management of these tumors in the past decade. We are finding more of these lesions than in years past since so many patients receive ultrasounds or CT scans for other reasons and these tumors are found incidentally. Cystic neoplasms are subdivided into serous, mucinous and intraductal papillary mucinous neoplasms. These lesions are described separately on this website but a few generalities pertain to all. The most important aspect of these lesions is to recognize them. They must be differentiated from benign pancreatic cysts as the treatment is distinctly different. Differentiation of benign cysts from cystic neoplasms of the pancreas can usually be made by a good history and physical exam by a physician familiar with these disorders. If a cystic neoplasm is suspected and the patient is symptomatic (abdominal pain), surgical ...

Cytological examination of breast lesions is frequently used in Portugal, but its diagnostic and prognostic values are controversial. The objective of this study was to evaluate the accuracy of cytological exam in the diagnosis of mammary lesions, compared to the histopathologic exam. We consulted 30 aspiration cytologies of canine mammary lesions and 15 of feline mammary lesions, which were gathered between the years 2011 and 2017 from the archives of the CEDIVET laboratory. Cytology diagnosed 12 benign lesions, 26 of border-line malignancy and 7 malignant. The histopathologic exam diagnosed 25 benign lesions and 20 malignant. The specific value, sensibility value, VPP and VPN were calculated for all cases. These parameters were then calculated exclluding the borderline malignancy diagnostics. Thus, sensivity increased from 39% to 71% in canine females and from 14% to 50% in female cats. The specificity was always 100% in the canine specie and in the feline it suffered a drop from 88% to 67%. ...

The objective of this project is the development of a 3D biodegradable matrix allowing the graft of autologous ovarian tissue or isolated follicles in patients with impaired fertility following a gonadotoxic treatment. This biofunctional fibrin-based matrix will limit the follicular loss due to post-transplant ischemic stress and will help to induce the formation of an extracellular ovarian-like matrix by promoting cell migration, cell proliferation and vascularization. In addition, a biodegradable textile pocket will also be developed to contain the tissue scaffold and to efficiently suture the graft at the implantation site.. ...
Pancreatic serous cystadenoma, also known as serous cystadenoma of the pancreas and serous microcystic adenoma, a benign tumour of pancreas. It is usually found in the head of the pancreas, and may be associated with von Hippel-Lindau syndrome. In contrast to some of the other cyst-forming tumors of the pancreas (such as the intraductal papillary mucinous neoplasm and the mucinous cystic neoplasm), serous cystic neoplasms are almost always entirely benign. There are some exceptions; rare case reports have described isolated malignant serous cystadenocarcinomas. In addition, serous cystic neoplasms slowly grow, and if they grow large enough they can press on adjacent organs and cause symptoms. Pathologists classify serous cystic neoplasms into two broad groups. Those that are benign, that have not spread to other organs, are designated "serous cystadenoma". Serous cystadenomas can be further sub-typed into microcystic, oligocystic (or macrocystic), solid, mixed serous-endocrine neoplasm, and ...
Causes of ovarian serous cystadenoma - What causes an ovarian serous cystadenoma to rupture do I need surgery if rupture? Pressure. The increased pressure and weak wall of the ovary can cause it to rupture - you do not need surgery if it does. You might consider getting it removed before it does though.
Background:Retroperitoneal sarcomas (RPS) are rare tumors composed of several well defined histologic subtypes. The aim of this study was to analyze patterns of recurrence and treatment variations in a large population of patients, treated at reference centers.Methods:All consecutive patients with primary RPS treated at 6 European and 2 North American institutions between January 2002 and December 2011 were included. Five, 8, and 10-year overall survival (OS) and crude cumulative incidence (CCI) of local recurrence (LR) and distant metastasis (DM) were calculated. Multivariate analyses for OS, CCI of LR, and DM were performed.Results:In all, 1007 patients were included. Median follow-up was 58 months (first and third quartile range 36-90). The 5, 8, and 10-year OS were 67% [95% confidence interval (CI), 63, 70), 56% (95% CI, 52, 61), and 46% (95% CI, 40, 53). The 5, 8, and 10-year CCI of LR and DM were 25.9 (95% CI, 23.1, 29.1), 31.3 (95% CI, 27.8, 35.1), 35% (95% CI, 30.5, 40.1), and 21% (95% ...
In the current study we provide quantitative interrogation of MC and MBOTs using amplicon-based hotspot sequencing. Our re-sequencing efforts confirmed KRAS mutations to be the most frequent molecular alteration amongst mucinous tumors, appearing more common in borderline malignancies over carcinomas (92.3 % versus 64.9 %, respectively; Fisher exact p = 0.0157). These values reflect what was previously reported [13]; however, improved sensitivity through the use of next generation sequencing identified KRAS mutations in three cases previously believed to be wild type (one MBOT and two MC). We further added to the complement of known RAS-activating mutations in observing mutations in BRAF (two MC), as well as previously unreported potentially RAS-activating alterations in FGFR2, ERBB2, and STK11, each affecting a single carcinoma. As noted above, inactivating mutation of STK11 could be considered an alternative mechanism to RAS-activation outside of typical KRAS/BRAF mutations [36, 37], an ...

Cystic tumors of the pancreas today are diagnosed more frequently in clinical practice, mainly due to an increased use of the modern advanced imaging modalities.. Bland cysts of the pancreas most often develop after chronic or acute inflammation of the pancreas. However, the current knowledge concerning the development of cystic neoplasias of the pancreas is still rudimentary.. Histopathologically, 90% of pancreatic cystic neoplasias are represented by four types: serous microcystic (SCN), mucinous cystic (MCN), intraductal papillary mucinous (IPMN) and solid pseudopapillary (SPN) neoplasias. Surgical treatment of these lesions can be highly challenging and occasionally demands complex surgical approaches that should be put in the hands of skilled pancreatic surgeons in experienced high-volume centers.. While some of the described cystic tumors are harmless, such as SCNs of the pancreas, others such as IPMN and MCN harbor relevant malignant potential. The differential diagnosis of these lesions ...

In the pelvis there is a large sepated cystic mass lesion seen occupying most of the pelvis and lower abdomen. This measures 14 x 9.3 x 11.1cm in size and demonstrates septation and predominantly fluid density. At its right posterolateral wall therte is also a slightly denser and minimal contrast enhancing mural nodule present. This measures approximately 17mm in size. I note the history of possible hydrosalpinx but I feel this lesion is too rounded and septated in appearance and likely represents a cystic tumour of the ovary ? right ovarian origin rather than hydrosalpinx. Suggest correlation with clinical history. I note there was a question raised previously with possible oophorectomy in the CT report in 2008. In understand the patient is to have a second gynaecological opinion tomorrow. ...

Serous cystic neoplasms represent about 30% of all cystic neoplasms of the pancreas and are characterized by their microcystic appearance (on imaging, macroscopically, and microscopically) and their benign biologic behavior. Modern diagnostic methodology allows the preoperative diagnosis with an acceptable accuracy. Currently, indications for resection of serous cystic neoplasms of the pancreas include the presence of symptoms, size , 4 cm (because these large neoplasms have a more rapid growth rate and probably will soon become symptomatic), and ...

Some authors believe the term microcystic serous adenoma is too limiting and that a macrocystic variant of the same neoplasm exists; the term serous cystadenoma is thus used for both morphologic variants.Nevertheless, the term macrocystic serous tumor is useful; these tumors are often misdiagnosed as either mucinous cystic neoplasms or pseudocysts. In fact, some tumors are misclassified even with intraoperative frozen section. Serum tumor markers with macrocystic serous tumors tend to be normal, although CA 125 and CA 19-9 are elevated in the cyst fluid in some of these tumors. The macrocystic variant of serous adenoma consists of a small uni- or bilocular cyst containing a thin wall without any mural nodules; these are indistinguishable from mucinous cystic tumors ...

The diagnostic modalities commonly used are ultrasonography and MRI. Ultrasound can diagnose the collection inside the uterus or vagina (secondary to obstruction, and may raise the differential of adenexal masses i.e. endometriomas and cystadenoma), but cannot identify the type of Mullerian anomaly, while MRI due to its multiplanar and tissue characterization abilities can give precise information about uterine morphology and about the continuity with each vaginal (obstructed and non-obstructed) lumen. MRI has more sensitivity in detecting the uterine contour, the shape of the cavity, the presence of a septum, as well as the presence of the associated pathology such as endometriosis, pelvic inflammation, and adhesions. Thus MRI is the gold standard method for accurate diagnosis and allows the most appropriate treatment option to be used. [3 ...
There are several types of cystic tumors or neoplasms of the pancreas, each with malignant potential that varies from nearly zero to up to 70% depending on the type. Distinguishing a neoplasm from a pseudocyst and distinguishing among the different types of neoplasm is often straightforward, but at times can be challenging.
A 48-year-old man with a history of hypertension, peripheral vascular disease and a 50-pack-year history of smoking, presented with new onset vertigo, tinnitus, diplopia and ataxia in January of 1978. There was no family history of any brain lesions, neurological symptoms or other contributory diseases. CT scan showed a radiolucent defect in the left cerebellar hemisphere with a possible mural nodule. In ensuing months, worsening symptoms were experienced with a corresponding increase in lesion size on re-imaging. Four months later, a left posterior fossa craniotomy was performed and revealed a single cystic lesion containing copious amounts of straw- colored fluid and a single mural nodule in the inferior portion of the cyst. Following resection, he was followed clinically until 1985 at which time follow-up was discontinued. He did well until January of 1993 when he presented with progressively worsening episodic headaches and retro-orbital pressure. In the following months, additional symptoms ...
The etiology and biological behavior of PRMCs are still unclear; however, some hypotheses have been proposed to explain the genesis of these tumors as follows: (1) heterotopic ovarian tissue [3, 11, 47], (2) monodermal variant of teratomas [22, 48], (3) intestinal duplication [49], and (4) coelomic metaplasia [4, 8, 12, 50]. In our case, ovarian-like stroma was histopathologically found in the tumor, although no definitive evidence of ovarian tissue was observed, which was also supported by the results of an immunohistochemical examination of the estrogen and progesterone receptors. These findings exclude the hypothesis of heterotopic ovarian tissue. In addition, the hypotheses of teratoma and intestinal duplication can also be excluded because of the lack of structures of teratoma or well-developed intestinal mucosa and smooth muscle. The fourth hypothesis, which is most well-described in the previous literature, is that PMRCs occur from invaginations of the peritoneal epithelium during ...

Perforation of the gallbladder is a rare, but potentially fatal complication of acute cholecystitis. Gallbladder perforations presenting electively as a space-occupying lesion of the liver are its rarest presentation. We report one such case, which was a diagnostic conundrum. A 50-year-old female presented with upper abdominal pain of 6 months duration. On examination, she was afebrile and had minimal tenderness in the right upper quadrant. All of her blood investigations were unremarkable, and her imaging showed features suggestive of a biliary cystadenoma. Intra-operatively, she was found to have a perforated gallbladder with intrahepatic extension. Cholecystectomy with abscess drainage was done, and her post-operative period was uneventful. Gallbladder perforations can have a myriad of presentations. We report a rare case of a perforated gallbladder mimicking a biliary cystadenoma. A high index of suspicion along with prudent decision-making can help in accurate pre-operative diagnosis, ...

Intraductal papillary mucinous neoplasms (IPMN) are cystic neoplasms with the potential for progression to pancreatic cancer. Recognized by the global medical community just over two decades ago, IPMN have gained great epidemiological and clinical relevance thanks to the widespread use of cross-sectional abdominal imaging, which has led to a surge in the number of incidental pancreatic cysts being diagnosed. As our understanding of this disease has improved, we now know that some IPMN have a very elevated risk of cancer and require surgical resection, while others are low-risk lesions and can be followed ...
High-grade appendiceal mucinous neoplasms (HAMN) are rare mucinous tumours of the appendix showing high-grade cytologic atypia, c.f. low-grade appendiceal mucinous neoplasms (LAMN). The distinction between both LAMN and HAMN is done on a histolog...
We report a case of a mural nodule of anaplastic spindle cell carcinoma in an ovarian mucinous cystic tumor of borderline malignancy. The thing is you may have more than one cysts and though 1 had ruptured, it can cause others to be inflamed or prone to break - like a chain reaction.. It seems that in patients whom follow a treatment against infertility with womanly hormones like FSH the risk of functional cysts to form is very high. Macrophages killed the cysts by phagocytosis, whereas neutrophils wiped out cysts through the secretion of MPO.. Individuals were followed up 24 instances of being pregnant 15 instances of infertility, pregnancy level 62. 5%; 5 instances confirmed recurrence, the recurrence rate was 5. 3%. Conclusions Laparoscopic surgical injury, quicker recovery, pelvic obvious vision, releasable pelvic adhesions in individuals with increased being pregnant rate of infertility, ovarian endometriosis must be used since the preferred way of cyst. ...

Mucin-hypersecreting intraductal pancreatic neoplasms were first described in 1982 and have been observed in increasing numbers since. They are observed primarily by endoscopic retrograde cholangiopancreatography (ERCP) and are characterized by an intraductal papillary neoplasm that secretes thick mucin, causing pancreatic duct dilatation and obstructive pancreatitis. Methods. Twenty patients are presented, 14 male and six female, with an average age of 59 ± 11 years. All patients presented with abdominal pain, and most had nausea and vomiting, weight loss, and documented pancreatitis. Of the preoperative studies, ERCP was positive in all patients.

Andrew Wilson, Thomas L. Perry, Ormond N. Panton. Full text (PDF, 366KB). Case. A previously healthy 49-year-old man presented to the emergency department with massive epistaxis. After undergoing sphenopalatine artery ligation, his hemoglobin dropped from 135 g/L at presentation to 100 g/L post-ligation. Three weeks later, he returned to the urgent care centre with diffuse abdominal pain, fatigue, and tachycardia (heart rate of 100 beats per minute). His blood pressure was 118/84 mmHg without orthostatic change, and his abdomen was diffusely tender without localized pain or peritoneal signs. His hemoglobin was 118 g/L (135-170), his MCV 85 fL (82-98), and his stool tested positive for occult blood. Other laboratory tests were normal, including TSH.. Twenty years earlier, the patient had been diagnosed with peptic ulcer disease. More recent endoscopy showed gastritis. As a result, on this presentation, he was treated with intravenous pantoprazole (Pantoloc) in the emergency department with the ...

Background and Aims: The recent development of microforceps for EUS through-the-needle biopsy (TTNB) sampling of the wall of pancreatic cystic lesions (PCLs) allows the collection of histologic specimens never handled and evaluated before by pathologists. We aimed to estimate the interobserver agreement among pathologists in evaluating such samples. Methods: TTNB specimen slides from 40 PCLs with worrisome features were retrieved and independently evaluated for specimen adequacy, presence of lining epithelium, grade of epithelial dysplasia, presence of ovarian type stroma, and specific diagnosis by 6 expert pathologists from 6 different tertiary care centers. The Gwets AC1 was used to assess interobserver agreement. Results: An almost perfect agreement was observed for specimen adequacy (AC1, .82; 95% confidence interval [CI], .79-.98), presence of lesional epithelium (AC1, .90; 95% CI, .86-.92), epithelial dysplasia (AC1, .97; 95% CI, .95-.99), and ovarian-like stroma (AC1, .90; 95% CI, ...
Answer: B. Polypoid endometrioma. Histology: A polypoid mass is seen projecting into the urethra. The mass has both solid and cystic components. The cystic components are lined variably by cuboidal cells w/o cilia, cuboidal or columnar cells with cilia, or urothelium. The intervening stroma has the appearance of endometrial stroma with condensation around the cysts. Clusters of prominent thick walled arterioles are evident. The tumor stroma was positive for estrogen receptor, progesterone receptor, and CD10.. Discussion: A characteristic features of spindle cell tumors in the kidney is that they tend to entrap native renal tubules, which then often become cystically dilated. This occurs in monophasic synovial sarcoma, angiomyolipoma, and in mixed epithelial and stromal tumor (MEST). In all these lesions, the tubules are lined by bland cuboidal epithelium which label with PAX8. Another feature of several renal lesions is that the stroma can undergo metaplasia to ovarian-like stroma which ...

There are well known differential diagnostic difficulties concerning these lesions. The aim is to review current literature on the diagnostic options and the following treatment for cystic lesions in the pancreas focusing on serous cystadenomas, primary mucinous neoplasm of the pancreas and mucinous cystadenocarcinomas, as well as intraductal papillary mucinous neoplasms, starting with excluding pseudocysts. A conservative approach is feasible in patients with a clinical presentation suggestive of an asymptomatic serous cystadenoma. Surgical management, as well as follow-up, is discussed for each of the types of neoplastic lesions, including an uncharacterized cyst, based on patient data, symptoms, serum analysis, cyst fluid analysis and morphological features. Aspects for future diagnostics and management ...
A 74-year-old woman was referred for further evaluation of a large pancreatic cystic lesion. She presented with abdominal discomfort, without weight loss, anorexia or history of pancreatitis or abdominal trauma. Physical examination revealed a large epigastric mass. A contrast-enhanced computed tomography (CT) showed a huge, well-defined, multiloculated cyst of 12cm in greatest dimension arising from the pancreatic body, with multiple wall calcifications, without typical imaging features of a particular pancreatic cystic neoplasm (Fig. 1). Endoscopic ultrasound (EUS) showed a multilocular cyst with a larger cyst (120mm×70mm) and a peripheral microcystic component (Fig. 2). EUS-guided fine-needle aspiration of 7mL of serous cystic fluid was performed from the largest cyst under prophylactic IV antibiotics. The sample had no malignant or mucus-producing cells and CEA (,2.5ng/mL) and amylase (41U/L) were within the reference values, making a serous cystadenoma the most likely diagnosis. Due to ...

The grading and staging of appendiceal mucinous neoplasms is challenging and fraught with terminology problems, but has critical prognostic and therapeutic implications. We utilized a small case series to examine the grading and staging systems of appendiceal mucinous neoplasms and outline the evidence for the new systems proposed in the upcoming 8th edition of the American Joint Committee on Cancer (AJCC) Staging Manual. We reviewed 33 cases of appendiceal mucinous neoplasms with available clinical follow-up data, 6 of which were widely disseminated in the peritoneum ...
Malignant change occurred in a benign, recurrent vaginal müllerian polyp. The patient, a 49 year old woman with cerebral palsy, presented with a polypoid mass in the vagina. At four years of age she had presented with a haemorrhagic polyp, and over the following years she had recurrent irregular bleeding and regrowth of the polypoidal mass, requiring a total of 10 operations to excise the polyp. Histological examination of the specimen showed typical müllerian features with tubal, endometrioid, and endocervical cell types. There were significantly abnormal nuclei, indicating low grade or borderline malignancy. Review of previous biopsies showed similar müllerian features but no atypia. This is the first reported case of borderline malignant change in a previously benign recurrent müllerian papilloma of the vagina. Definitive radical surgery or radiotherapy is contraindicated in this patient and she remains under follow up.. ...
Hepatic (biliary) cystadenomas are rare multilocular cystic tumors of the liver that are derived from the biliary epithelium and are predominantly located in the right hepatic lobe. These tumors usually involve the hepatic parenchyma (approximately 85% of cases) and occasionally the extrahepatic biliary tract.
Purpose: Pancreatic cysts are common and pose diagnostic and management challenges. Pancreatic cyst fluid markers have the potential to aid in the management of cysts with concerning imaging findings. Our aim was to evaluate cyst fluid methylated DNA markers for their accuracy for predicting the histologic grade of neoplastic pancreatic cysts. Experimental Design: Pancreatic cyst fluid samples from 183 patients (29 discovery, 154 validation) aspirated after surgical resection were analyzed for methylated DNA at selected genes (SOX17, BNIP3, FOXE1, PTCHD2, SLIT2, EYA4 and SFRP1) using methylation-specific droplet-digital PCR (dd-QMSP). Methylated DNA levels were evaluated for their accuracy at predicting the grade of dysplasia of the pancreatic cyst. Results: All six markers evaluated in the validation set could accurately distinguish high-risk cystic neoplasms (with high-grade dysplasia and/or associated invasive cancer) from low-risk cysts (lower grades of dysplasia) with accuracies from 79.8 ...

The vermiform appendix is a blind-ended tube that projects from the cecum. The term vermiform comes from Latin and it means worm-shaped. Thus, the vermiform appendix is a projection that is worm-shaped connected to the cecum. The average size of a human vermiform appendix is about 9 cm in length whereas the diameter is generally between 7 and 8 mm. It is often found in the lower right quadrant of the abdomen. Its position corresponds to the so-called McBurneys point. For herbivores, the vermiform appendix is essential since it is responsible for the breaking down of cellulose present in the cell wall of plants. In humans and other animals, it became a redundant process since it has no particular daily function. Nevertheless, it is postulated to be associated with maintaining gut flora, particularly during a recovery from diarrhea.1 ...

Mucocele of the appendix is rare and represents only the tip of the iceberg of underlying benign and malignant pathological processes. Intraoperative diagnosis is also tricky because the inflammation of the appendix often hides the tumor. The preoperative diagnosis is essential to differentiate appendiceal mucocele from acute appendicitis as the treatment varies from open surgical versus laparoscopic surgical approach and for decreasing intraoperative and postoperative morbidity and mortality rate. We present three cases of appendiceal mucocele. The purpose of this paper is to make the physicians aware of the entity, its associations and the effect on management. This review will provide radiologic and pathologic correlation for the preoperative diagnosis of benign and malignant causative processes and differential diagnostic considerations.
A 40-year-old Japanese woman, who previously had undergone choledocho-jejunostomy in childhood for a congenital choledocal cyst, presented with right-sided chest pain. Computed tomography and ultrasonography demonstrated a right pleural effusion and a 10-cm unilocular hepatic cystic lesion with no solid component. These findings suggested a non-neoplastic cyst or cystadenoma. However, intracystic fluid aspirated had high concentrations of carbohydrate antigen 19-9 and carcinoembryonic antigen. Cytology of the pleural effusion demonstrated malignant cells. During exploratory laparo- and thoracotomy, a hepatic cystadenocarcinoma with invasion of the diaphragm and pleural dissemination was discovered. This case demonstrates that malignancy should be ruled out when a patient with an intrahepatic unilocular cystic lesion presents with atypical symptoms and findings, such as chest pain, pleural effusion, and high serum concentration of tumor markers. We believe that intrahepatic cystic lesions should be
Case report: A 50 year old woman presented with lower abdominal pain and fullness. On radiological examination, a left ovarian, predominantly cystic mass about 10cm in diameter was found along with an uterine nodule, 1.5cm in diameter, presumed to be a leiomyoma. The ovarian cyst on histology was diagnosed as ESS arising in a serous cystadenoma. The uterine nodule was diagnosed as ESN since there was no myometrial or vascular invasion ...

Results 2622 patients were included. Seventy-four per cent were women, and median age at diagnosis was 58 years (16-99). Patients presented with non-specific abdominal pain (27%), pancreaticobiliary symptoms (9%), diabetes mellitus (5%), other symptoms (4%) and/or were asymptomatic (61%). Fifty-two per cent of patients were operated on during the first year after diagnosis (median size: 40 mm (2-200)), 9% had resection beyond 1 year of follow-up (3 years (1-20), size at diagnosis: 25 mm (4-140)) and 39% had no surgery (3.6 years (1-23), 25.5 mm (1-200)). Surgical indications were (not exclusive) uncertain diagnosis (60%), symptoms (23%), size increase (12%), large size (6%) and adjacent organ compression (5%). In patients followed beyond 1 year (n=1271), size increased in 37% (growth rate: 4 mm/year), was stable in 57% and decreased in 6%. Three serous cystadenocarcinomas were recorded. Postoperative mortality was 0.6% (n=10), and SCNs related mortality was 0.1% (n=1). ...

Structures may either be primary or secondary retroperitoneal, depending on their developmental history. A primary retroperitoneal structure (i.e. kidneys, inferior vena cava, aorta, proximal rectum, ureters, and suprarenal glands) develops and remains retroperitoneal, whereas secondary retroperitoneal structures (i.e. the 2nd and 3rd parts of the duodenum, the ascending and descending colon, and most of the pancreas) begin development intraperitoneal, but eventually are drawn retroperitoneal ...
Some authors divide this syndrome into a typical or isolated form, consisting of symmetrical nonfunctioning muscular buds (müllerian duct remnants) and normal fallopian tubes, and an atypical,more generalized form consisting of aplasia of one or both buds and with or without fallopian tube dysplasia. Some duct remnants are cystic. Differentiation between the two forms is made on the basis of laparoscopic findings, although MRI can often suggests a diagnosis. The atypical form is associated with skeletal, renal, and ovarian abnormalities ...

International Consensus Guidelines have established how to diagnose and manage pancreatic cystic tumors [7]. Although their clinical, radiological and pathological features have been defined, in some cases the differential diagnosis between mucinous forms is difficult [8].. In our case the assessment of a correct preoperative diagnosis was difficult due to the clinical and radiological findings. Patients age and main duct dilatation were elements in favor of IPMN, while female gender and the involvement of the body of the gland leaned towards MCN. However the diagnosis of IPMN was excluded as there was no communication between the cystic mass and the main pancreatic duct.. Tumor size, peripheral calcifications, irregular septa, and the presence of an intramural nodule pointed towards malignant transformation and led to surgical resection. Indeed all these radiological findings are very frequently associated with malignant histology [9].. On the basis of microscopic criteria (nuclear atypia, ...

A 10-year-old female child was referred to our department with complaints of right lower abdominal pain which lasted for 6 months. She had no history of vomiting. On examination, her abdomen was soft, non-tender, with no palpable mass, and not distended. Abdominal sonography revealed a 5 by 4.5cm simple cyst in the right adnexa with a 1.7mm wall thickness, with no solid component or septation. Her right ovary was not seen separately. Her left ovary and uterus showed no abnormalities. Malignancy work-up revealed nothing suspicious (Beta-HCG: 2.9 IU/L, AFP: 1.3ng/mL, CA125: 10.9, all within normal range). A robotic-assisted complete cyst excision with preservation of the ovary was performed using 3 arms of the Da Vinci Xi™ robotic surgical system. The patient resumed oral food intake the same evening. He was discharged the following day within 24 hours of the procedure on paracetamol only. The patient was healthy and well. The biopsy reported a benign serous cystadenoma. At a 1-year follow-up, ...
