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)
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.
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)
A benign neoplasm of the ovary.
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)
Tumors or cancer of the APPENDIX.
A retention cyst of the salivary gland, lacrimal sac, paranasal sinuses, appendix, or gallbladder. (Stedman, 26th ed)
Tumors or cancer in the BILIARY TRACT including the BILE DUCTS and the GALLBLADDER.
Tumors or cancer of the BILE DUCTS.
A worm-like blind tube extension from the CECUM.
A benign tumor of the intrahepatic bile ducts.
Any fluid-filled closed cavity or sac that is lined by an EPITHELIUM. Cysts can be of normal, abnormal, non-neoplastic, or neoplastic tissues.
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.
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.
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).
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.
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)
Pathological developments in the CECUM.
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.
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.
Tumors or cancer of the ENDOCRINE GLANDS.
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.
A condition characterized by the complete absence of SEMEN. This disorder should be differentiated from AZOOSPERMIA, absence of sperm in the semen.
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)
Tumors or cancer of the SALIVARY GLANDS.
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)
Surgery performed on the male genitalia.
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.
Accessory salivary glands located in the lip, cheek, tongue, floor of mouth, palate and intramaxillary.
Tomography using x-ray transmission and a computer algorithm to reconstruct the image.
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.
General term for CYSTS and cystic diseases of the OVARY.
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.
Pathological processes of the PANCREAS.
Passages external to the liver for the conveyance of bile. These include the COMMON BILE DUCT and the common hepatic duct (HEPATIC DUCT, COMMON).
Surgical removal of the vermiform appendix. (Dorland, 28th ed)
Surgical removal of the pancreas. (Dorland, 28th ed)
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)
An adenocarcinoma producing mucin in significant amounts. (From Dorland, 27th ed)
A clinical syndrome with acute abdominal pain that is severe, localized, and rapid in onset. Acute abdomen may be caused by a variety of disorders, injuries, or diseases.
Islands lying between southeastern North America and northern South America, enclosing the Caribbean Sea. They comprise the Greater Antilles (CUBA; DOMINICAN REPUBLIC; HAITI; JAMAICA; and PUERTO RICO), the Lesser Antilles (ANTIGUA AND BARBUDA and the other Leeward Islands, BARBADOS; MARTINIQUE and the other Windward Islands, NETHERLANDS ANTILLES; VIRGIN ISLANDS OF THE UNITED STATES, BRITISH VIRGINI ISLANDS, and the islands north of Venezuela which include TRINIDAD AND TOBAGO), and the BAHAMAS.

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. (From Stedman, 25th ed & Holland et al., Cancer Medicine, 3d ed, p1182)
Cyst occurring in a persistent portion of the urachus, presenting as an extraperitoneal mass in the umbilical region. It is characterized by abdominal pain, and fever if infected. It may rupture, leading to peritonitis, or it may drain through the umbilicus.
An embryonic structure originating from the ALLANTOIS. It is a canal connecting the fetal URINARY BLADDER and the UMBILICUS. It is normally converted into a fibrous cord postnatally. When the canal fails to be filled and remains open (patent urachus), urine leaks through the umbilicus.

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)

AU - Son, Gil Soo. AU - Kim, Seung Joo. AU - Moon, Hong Young. PY - 2004/12. Y1 - 2004/12. N2 - Primary mucinous cystic cystadenomas of the retroperitoneum are very rarely encountered, and there have been only about 30 cases reported in the literature. The histogenesis of primary mucinous cystadenomas is unclear. Most authors suggested that it develops through mucinous metaplasia in a pre-existing mesothelium-lined cyst. Complete surgical excision is the only treatment and it is required for the final diagnosis and cure. We present here a case report of a 38-year-old Korean woman with primary retroperitoneal cystadenoma. It was a thin-walled, multilocular cyst with a dominant loculus that measured 10.0×7.5×5.5 cm3 in size, and to the best of our knowledge, this is the first such case to be reported in in ...

Ovarian Mucinous Cystadenoma Complicating Pregnancy- A Case Report Padmini Kumari and Mala Sinha Gynae and Obs, Mahavir Cancer Sansthan Diagnosis of
Mucinous cystadenomas are rare benign epithelial ovarian tumors which are commonly found in middle aged women and are bilateral in 10 percent cases. These tumors are known to grow to massive sizes with historical recordings of removal of a 137.4 kg tumor by Ohanlan in 1994.[2] Our patient had a 21x19.5x13 cm mass that weighed 3.650 kg and could luckily be removed intact despite her history of 3 caesarean sections in the past. Traditionally the epithelial lining of mucinous cystadenomas can be one of 3 types - endocervical, intestinal or the mullerian type. Our patient had a mucinous borderline tumor of the intestinal type with only atypia. The patient fell into FIGO stage 1a for borderline ovarian tumors.[4] The 5 year survival in such patients is usually more than 99%.[5] The cytoplasm of epithelia of low malignant potential mucinous tumours is more basophilic than the epithelium of mucinous cystadenoma. They also show occasional evidence of inflammatory infilitrates. In general in borderline ...
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 ...

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 ...

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.

Summary Background Data: Mucinous cystadenomas of the pancreas are premalignant cystic lesions. Resection is the preferred treatment but often requires a pancreatoduodenectomy or a distal pancreatectomy with or without a splenectomy. Although these procedures can now be performed with a low mortality rate, substantial morbidity still occurs, especially in patients who have an otherwise normal pancreas.

Answer: Mucinous cystadenoma. Histology: none provided. Discussion: This cystic mass is partially denuded and partially lined by benign mucinous epithelium. The wall is thick and fibrotic with chronic inflammation. Focal areas with aggregates of foamy histiocytes and granulation tissue are also noted in the cyst lumen. No extravasated mucin or ovarian type stroma is identified. The tumor is adherent to the serosal surface/deep aspect of muscularis propria of the colon. The appendix and ascending colon were unremarkable. Immunostains demonstrate that the mucinous epithelium is CK7+, CK20-, and MUC2- but MUC5+ and beta-catenin negative. This staining pattern is most consistent with an ovarian type mucinous neoplasm. Since no ovarian tissue was submitted and as per the surgeon the tumor was away from the ovaries these findings may represent a mucinous cystadenoma arising in ectopic ovarian tissue.. ...
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. ...

A 71-year-old woman was referred to our institution for further investigation of epigastric pain. The patient had been detected to have a multilocular cyst in the medial segment of the liver measuring 69 mm in diameter at another hospital 2 years ago, and the diameter of the cyst had increased to 90 mm. Although the cyst had gradually increased in size, there was no evidence of mural nodules. As we were concerned about the malignant potential of the lesion, a left hepatic segmentectomy was performed. Pathologically, the cyst was lined by columnar and cuboidal epithelium with low-grade atypia. The epithelium covered an ovarian-like stroma, and the diagnosis was mucinous cystic neoplasm of the liver (MCN-L) with low-grade intraepithelial neoplasia. MCN-L is a rare disease and its characteristics are still poorly understood. MCN-L occurs at a lower frequency as compared to the counterpart of MCN of the pancreas, further investigations are necessary to clarify the biological malignancy of MCN-L.
Kayla Rahn couldnt lose weight and started experiencing a lot of pain. A 50-pound cyst was to blame. Doctors had not seen a such a large mucinous cystadenoma.
Answer: Mucinous cystic neoplasm. Histology: This unusual neoplasm is has two distinct components. The stroma has the appearance of ovarian stroma, and indeed the stromal cells immunolabeled for estrogen and progesterone receptors. The second component is composed of epithelial cells. These cells are mostly cuboidal and occasionally have a hobnail appearance.. Discussion: Mucinous cystic neoplasms of the pancreas occur in women more frequently than they do in men, and mucinous cystic neoplasms have a distinctive ovarian-type of stroma. The neoplasm presented arose in a woman and it has ovarian stroma. One might expect that it is a classical mucinous cystic neoplasm, but two things are peculiar about this case. First, the epithelial cells do not form large cysts. Second, the epithelial cells are not columnar mucin-producing cells. Instead, they are mostly cuboidal and somewhat hob-nailed in appearance. This histologic appearance is almost identical to the mixed epithelial and stromal tumor ...
Context: Ovarian tumours represent about 30% of all cancers of the female genital system. They manifest in a wide spectrum of clinical, morphological and histological features. Aim: To study the frequency of incidence of different histopathological types of ovarian tumours in our institute. Materials and Methods: This retrospective study included 257 cases of histopathologically proven ovarian tumours, reported in the Department of Pathology of a rural tertiary care referral hospital, over a 12 year period (January 2000 to December 2011). These were classifi ed according to the WHO classifi cation of ovarian tumours (2003). Clinical presentation of the patients was analysed from archived case records. Results: Of the 257 tumours studied, 162 (63.04%) were benign, 15 (5.84%) were borderline and 80 (31.12%) were malignant. Surface epithelial tumours were the most common (68.48%) followed by germ cell tumours (15.95%). Mucinous cystadenomas (32.69%) were the most common benign tumours, while serous ...
The types of treatments given for borderline malignancy ovarian tumours are based on the unique needs of the woman. Being able to have children in the future is important for some women, so doctors will consider this when planning treatment.

However, the incidence and severity of the complications of obstruction are not well documented. The aim of the study was to investigate the clinical presentation and outcome of 10 patients with IPMT. Methods: All cases of IPMT diagnosed between 1994 and 1999 were reviewed. Results: Four of the 10 patients developed severe acute illness with systemic complications resulting from ductal obstruction. Three suffered acute cholangitis with sepsis, and 1 developed necrotizing pancreatitis and ARDS. There was 1 postoperative death in a patient with adenocarcinoma. All other patients are ...
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 ...
Biliary cystadenomas are benign but potentially malignant cystic neoplasms, which classically contain mesenchymal stroma similar to ovarian tissue. We report a case of an extra-hepatic biliary cystadenoma with mesenchymal stroma along with a discussi
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, ...
Before 1978, where cystic tumors of the pancreas were concerned, pathologists only differentiated between cystic adenomas and cystadenocarcinomas. Recently, however, further tumor entities have been introduced. We now differentiate between the generally benign serous cystic adenoma, the potentially malignant mucinous cystadenoma, the possibly malignant papillary cystic tumor, and the always malignant mucinous cystadenocarcinoma. Other rare tumors include the solid cystic acinous-cell tumor, the cystic islet tumor, and mucinous ductal hyperplasia. Because of their slow growth and primary displacement nature, all of these tumors can usually be detected only after they have attained considerable size. Computed tomography (CT), sonography and endoscopic retrograde cholangiopancreatography (ERCP) have an established role in diagnosis. With these methods, as a rule, it is possible to identify pseudocysts; however, differentiation between the individual tumor types is almost impossible. In our study ...
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.
To provide criteria for the differential diagnosis of serous cystic neoplasms (SCNs) and mucinous cystic neoplasms (MCNs) by analyzing the imaging features of these two neoplasms by endoscopic ultrasound (EUS). From April 2015 to December 2017, a total of 69 patients were enrolled in this study. All patients were confirmed to have MCNs (31 patients) or SCNs (38 patients) by surgical pathology. All patients underwent EUS examination. The observation and recorded items were size, location, shape, cystic wall thickness, number of septa, and solid components. Head/neck location, lobulated shape, thin wall and | 2 septa were the specific imaging features for the diagnosis of SCNs. When any two imaging features were combined, we achieved the highest area under the curve (Az) (0.824), as well as the appropriate sensitivity (84.2%), specificity (80.6%), positive predictive value (PPV) (84.2%), and negative predictive value (NPV) (80.6%). Body/tail location, round shape, thick wall and 0-2 septa were the
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 ...
Journal of Clinical and Diagnostic Research aims to publish findings of doctors at grass root level and post graduate students, so that all unique medical experiences are recorded in literature.
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. ...
