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 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)
Tumors or cancer of the APPENDIX.
A worm-like blind tube extension from the CECUM.
A benign neoplasm of the ovary.
A retention cyst of the salivary gland, lacrimal sac, paranasal sinuses, appendix, or gallbladder. (Stedman, 26th ed)
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)
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 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)
Excision of all or part of the liver. (Dorland, 28th ed)
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)

It is cured by surgical removal. (Stedman, 25th ed; Rook et al., Textbook of Dermatology, 4th ed, p2410)

Epithelial thyroid tumors in cows. (1/197)

From 1964 to 1973, 370 tumors were collected from cows of unknown age. Ten (2.7%) of these were primary thyroid tumors. Three were malignant. The benign tumors were solitary encapsulated adenomas in the parenchyma with more or less defined trabeculae, tubular, and microfollicular pattern. One of the malignant tumors was a cystic papillary adenocarcinoma, and two were small cell carcinomas consisting of small, sometimes binuclear, pleomorphic cells.  (+info)

Vascular endothelial growth factor levels in ovarian cyst fluid correlate with malignancy. (2/197)

Ovarian cancer is a richly vascularized neoplasm with solid and cystic components. The purpose of this study was to determine whether cyst fluid could be used to quantitatively evaluate production of angiogenic factors in ovarian lesions. ELISA was used to measure vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in the cyst fluid of patients with ovarian cancer (n = 13), benign cysts and cystadenomas (n = 23), borderline tumors (n = 5), and functional cysts (n = 8). VEGF levels were markedly elevated in the fluid of malignant cysts (38.5+/-8.2 ng/ml) as compared with benign (1.6+/-0.4 ng/ml; P < 0.001), borderline (5.7+/-1.5 ng/ml; P < 0.001), or functional cysts (3.8+/-2.0 ng/ml; P < 0.001). The presence of VEGF in cancer cells was confirmed by immunohistochemistry. Follow-up of patients with malignant and borderline lesions demonstrated a correlation between VEGF levels in cyst fluid and tumor recurrence (P = 0.03). bFGF in malignant cysts was either undetectable or very low (0.3+/-0.2 ng/ml), and no significant differences were found in bFGF levels among malignant, benign, borderline, and functional cysts. This study demonstrates that ovarian malignancy is associated with dramatic elevation of VEGF levels in ovarian cyst fluid. Conversely, there is no correlation between cyst fluid bFGF levels and malignant transformation. The high levels of VEGF in malignant cysts are consistent with the hypothesis that this growth factor plays an important role in ovarian cancer related-angiogenesis and tumor progression and represents a potentially important target of antiangiogenic therapy.  (+info)

Mucin Hypersecreting Intraductal Papillary Neoplasm of the pancreas. (3/197)

Mucin Hypersecreting Intraductal Papillary Neoplasm is a rare neoplasm that arises from ductal epithelial cells. This entity is distinct from the more commonly known Mucinous Cystadenoma or Mucinous Cystadenocarcinoma. Despite this distinction, it has been erroneously categorized with these more common cystic neoplasms. Characteristic clinical presentation, radiographic, and endoscopic findings help distinguish this neoplasm from the cystadenomas and cystadenocarcinomas. Histopathologic identification is not crucial to the preoperative diagnosis. This neoplasm is considered to represent a premalignant condition and, therefore, surgical resection is warranted. Prognosis, following resection, is felt to be curative for the majority of patients. We present two cases of Mucin Hypersecreting Intraductal Papillary Neoplasm and discuss their diagnosis and surgical therapy.  (+info)

Tsc2(+/-) mice develop tumors in multiple sites that express gelsolin and are influenced by genetic background. (4/197)

Tuberous sclerosis (TSC) is an autosomal dominant genetic disorder in which benign hamartomas develop in multiple organs, caused by mutations in either TSC1 or TSC2. We developed a murine model of Tsc2 disease using a gene targeting approach. Tsc2-null embryos die at embryonic days 9.5-12.5 from hepatic hypoplasia. Tsc2 heterozygotes display 100% incidence of multiple bilateral renal cystadenomas, 50% incidence of liver hemangiomas, and 32% incidence of lung adenomas by 15 months of age. Progression to renal carcinoma, fatal bleeding from the liver hemangiomas, and extremity angiosarcomas all occur at a rate of less than 10%. The renal cystadenomas develop from intercalated cells of the cortical collecting duct and uniformly express gelsolin at high levels, enabling detection of early neoplastic lesions. The tumor expression pattern of the mice is influenced by genetic background, with fewer large renal cystadenomas in the outbred Black Swiss background and more angiosarcomas in 129/SvJae chimeric mice. The slow growth of the tumors in the heterozygote mice matches the limited growth potential of the great majority of TSC hamartomas, and the influence of genetic background on phenotype correlates with the marked variability in expression of TSC seen in patients.  (+info)

Alterations in the expression of the DNA repair/redox enzyme APE/ref-1 in epithelial ovarian cancers. (5/197)

The DNA base excision repair pathway is responsible for the repair of alkylation and oxidative DNA damage. A crucial step in the base excision repair pathway involves the cleavage of an apurinic/apyrimidinic (AP) site in DNA by an AP endonuclease (APE). The major AP endonuclease in mammalian cells is APE/ref-1, a multifunctional enzyme that acts not only as an AP endonuclease but as a redox-modifying factor for a variety of transcription factors. The purpose of this study was to determine the expression of APE/redox factor-1 (ref-1) in ovarian tissues, particularly ovarian cancers. Formalin-fixed, paraffin-embedded specimens of ovarian tissues (normal, various benign conditions, and epithelial cancers) were studied using both polyclonal and monoclonal antibodies to APE/ref-1. The relationship between APE/ref-1 protein levels and DNA repair activity was studied in ovarian Hey and Hey-C2 cell lines using Western blot and a specific AP-site oligonucleotide cleavage assay. Hey and Hey-C2 cells were fractionated, and the nuclear and cytoplasmic extracts were quantitated for protein levels and assessed for APE/ref-1 with Western blot. Normal ovarian tissues consistently demonstrated strong nuclear staining of the surface epithelium, epithelial inclusions, corpora lutea and albicantia, and stroma. Cytoplasmic staining was absent. A similar pattern was seen for benign conditions including endometriosis. Low malignant potential ovarian cancers stained in a pattern similar to normal ovarian and nonneoplastic tissues; however, two specimens also had areas of cytoplasmic staining. Epithelial ovarian cancers were remarkably different from all other ovarian tissues studied. Both nuclear and cytoplasmic staining of the malignant epithelium were seen and ranged from strong to weak, often with considerable staining heterogeneity within the same tumor. The AP-site oligonucleotide cleavage assay indicated that APE/ref-1 protein levels correlate well with DNA repair activity. The increased levels of APE/ref-1 in the Hey-C2 cells was mainly attributable to increased cytoplasmic enzyme. APE/ref-1 immunoreactivity is altered in malignant ovarian tumors. Further studies will determine whether the altered expression and subcellular location reflect changes in redox regulatory functions.  (+info)

Accumulation of collagen in ovarian benign tumours. (6/197)

Extracellular matrix components of benign ovarian tumours (cystadenoma, adenofibroma, cystadenofibroma) were analysed. The investigated tumours contained twice as much collagen than control ovarian tissues. Significant alterations in mutual quantitative relationships between collagens of various types were observed. The proportion of type I collagen decreased and that of type III collagen increased. The accumulation of collagen was accompanied by a reduction in sulphated glycosaminoglycan content whereas the amount of hyaluronic acid was not changed. Dermatan sulphate was the most abundant glycosaminoglycan component. It is suggested that the accumulation of collagen (natural barrier to the migration of tumour cells) and underexpression of glycosaminoglycans/proteoglycans (binding some growth factors and interleukins) may exert an inhibitory effect on tumour growth.  (+info)

Contrast-enhanced sonography in the examination of benign and malignant adnexal masses. (7/197)

Our objective was to characterize the properties of an intravascular ultrasonographic contrast agent in examination of adnexal masses and to compare contrast agent properties between benign and malignant adnexal tumors. Fifty-eight consecutively examined women with suspected ovarian tumors were examined preoperatively by power Doppler ultrasonography, first without and then with contrast agent enhancement (Levovist). Fourteen women had ovarian cancer, 3 had borderline ovarian tumors, 18 had benign ovarian neoplasms, and 23 had functional adnexal cystic masses or endometriomas. The effect of the contrast agent was evaluated visually and by using computerized power Doppler signal intensity measurements. In visual evaluation, the brightness of the power Doppler signal and the amount of recognizable vascular areas increased in each tumor after contrast agent administration. The number of vessels in power Doppler ultrasonograms, both before and after contrast agent enhancement, was significantly higher in malignant than in benign adnexal masses, as also was the increase in the number of recognizable vessels after contrast agent administration. Contrast agent uptake time was significantly shorter in malignant than in benign tumors. No significant differences were found in the power Doppler signal intensities or their changes between benign and malignant tumors. In conclusion, use of sonographic contrast agent facilitates imaging of tumor vessels. For differentiation of benign and malignant tumors, the kinetic properties of the contrast agent, such as uptake and washout times, may have more potential than the use of the contrast agent in anatomic imaging of the tumor vessels.  (+info)

Molecular characterization of pancreatic serous microcystic adenomas: evidence for a tumor suppressor gene on chromosome 10q. (8/197)

Pancreatic serous microcystic adenomas (SCAs) are rare, benign tumors with a striking female preference. Virtually no information is available about chromosomal or genetic anomalies in this disease. We performed extensive molecular characterization of 21 cases of formalin-fixed, paraffin-embedded sporadic SCAs consisting in genome-wide allelic loss analysis with 79 microsatellite markers covering all 22 autosomes, assessment of microsatellite instability, and mutational analysis of the VHL, K-ras, and p53 genes in nine cases for which frozen tissue was available. Although no case showed microsatellite instability of the type seen in mismatch repair-deficient tumors, a relatively low fractional allelic loss of 0.08 was found. Losses on chromosome 10q were the most frequent event in SCAs (50% of cases), followed by allelic losses on chromosome 3p (40% of cases). Moderately frequent losses (>25% of cases) were found on chromosomes 1q, 2q, and 7q. The VHL gene, located on chromosome 3p, had somatic inactivating mutations in two of nine cases (22%), whereas no mutations were found in either K-ras or p53, in agreement with the finding that all 21 cases stained negative for p53 by immunohistochemistry. Our study indicates that the involvement of chromosomal arms 10q and 3p is characteristic of SCAs and that the VHL gene is involved in a subset of sporadic cases.  (+info)

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 ...

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, ...
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.

Peripheral papillary adenomas of the lung are uncommon neoplasms (only ten cases have been described so far in the English literature) composed predominantly of type-II pneumocytes and generally considered benign. We describe here two additional cases of this lung tumor. In both cases histological examination revealed an encapsulated papillary neoplasm with invasion of the capsule and, in one case, invasion of the adjacent alveoli and visceral pleura too. The proliferative index (Ki67) was less than 2% and the epithelial cells were positive for cytokeratins, surfactant apoproteins (SP), and nuclear thyroid transcription factor-1 (TTF-1). Ultrastructurally, the epithelial cells showed the characteristic surface microvilli and cytoplasmic lamellar inclusions of type-II cells. Review of the literature has revealed two other cases of peripheral papillary adenoma of type-II pneumocytes with infiltrative features. Thus, we propose replacing the term peripheral papillary adenoma with peripheral papillary tumor
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.
Novel treatment approaches are needed for patients with acute lymphoblastic leukemia (ALL) who respond poorly to current therapies. The genotypic diversity identified recently by next generation sequencing technologies within ALL calls for individualized novel strategies. However, functional correlations of oncogenic lesions with drug response profiles are ill defined for ALL. We have established an imaging-based cell viability analysis platform to generate drug response profiles for primary patient-derived ALL samples co-cultured with mesenchymal stroma cells, expecting to derive functional information directly from individual patient samples. Such response profiles may mirror perturbations in relevant cellular programs that could be exploited therapeutically. Our pipeline integrates high-content screening, newly developed bioinformatics tools and biochemical approaches. We screened a library of 65 compounds for activity in 37 precursor B-ALL and 23 T-ALL samples including refractory cases. ...

Serous cystadenomas are a type of cystic neoplasm of the pancreas. These lesions are more frequent in those greater than age 70 and are more common in women. They are commonly quite large at the time of diagnosis measuring on average 5-8cm. Even though they are large they almost never cause jaundice and uncommonly will block the pancreatic duct. Thus, they are usually asymptomatic and are most usually found on diagnostic imaging performed for other reasons.. ...
1086 Normal cells in culture have a limited lifespan as they undergo two mortality checkpoints known as senescence (M1) and crisis (M2). We used an epithelial cell strain called ML-10 derived from benign ovarian cystadenomas. The cells were transfected with SV40 Large T Antigen, thus allowing them to bypass the M1 mortality checkpoint but not M2. Crisis occurred after 45 to 50 population doublings in vitro and was characterized by widespread apoptosis resulting from accumulation of severe numerical chromosomal changes. These chromosomal changes were first manifested as tetraploidy, followed by aneuploidy. We hypothesized that tetraploidy was due to G2 arrest and that the ensuing aneuploidy developed in cells that had overcome such arrest and re-initiated a new cycle. This is supported by the fact that treatment with caffeine, which is known to abrogate cells in the G2/M phase during cell cycle progression, caused a decrease in the percentage of cells undergoing G2/M arrest, thereby resulting in ...

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 ...

I believe this is known as Proteus syndrome. The following is from a paper I am writing on the cytological findings of a hydrocele fluid from a boy with Proteus syndrome (I must pull my finger out and submit it). As an aside, it is believed that the elephant man suffered from this disorder. Proteus syndrome is a rare disorder and it estimated that there are only several hundred patients affected. It is postulated that the syndrome is caused by a post-zygotic mosaic alteration in a gene that is lethal in its non-mosaic state (4). Apart from connective tissue and epidermal nevi, disproportionate overgrowth of some bones and other malformations, bilateral ovarian cystadenomas are regarded as having diagnostic value in Proteus syndrome when occurring in the first two decades of life. Papillary lesions, resembling common epithelial ovarian tumours are rare in the testis with only a handful being described in pre-pubertal males (4). It has been suggested that these papillary lesions, so called ...

Good afternoon, dear colleagues. The topic of this lecture is typical pathological processes involving the system of microcirculation. Microcirculation is most important part of general hemodynamics. The definition of microcirculation: microcirculation is blood flow in micro vessels with diameter less than 100 micrometers. But, of course, the quantitative border is not the most essential. Most essential is that microcirculation is tightly related to fluid exchange between the blood and tissues, the microcirculatory dynamics includes microcirculation in blood vessels, flow of lymph and extravasal tissue fluid. We need to emphasize that microvasculature represents a kind of frame or if you want tissue plumbing and sanitation system. But the tubes of this plumbing and sanitation system are embedded, built into the walls of a house. And microcirculation is closely associated with mesenchymal stroma or connective tissue, skeleton of all organs and tissues. At the stromal and vascular metrics, 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. ...
Background Information: Mature cystic teratomas (MCTs) and serous cystadenomas are the two most common ovarian neoplasms encountered in clinical practice. Majority of ovarian masses encountered in clinical practice is benign. Approximately 15-25% of ovarian neoplasms are MCTs, also known as dermoids. Ultrasound (US) is often the first imaging test in the diagnosis of an ovarian mass across all ages. In the United States, there is a propensity for follow-up MRI and CT when an ovarian mass is encountered by US. US has multiple desirable attributes, which include wide availability, relatively quick procedure, no peripheral IV catheter placement for iodinated or gadolinium contrast injection, lack of ionizing radiation, and relatively low cost. The purpose of this exhibit is to review the sonographic features of MCTs with correlation to CT and MRI, as well as correlation to the various components of the three germ layers found in ovarian MCTs ...

BACKGROUND: The indications for resection of pancreatic cystic lesions (PCL) are often complex and the operative risk has to be balanced against the risk of malignant transformation. The aim of the study was to provide a synopsis of the current treatment results of minimally invasive surgery for PCL. METHODS: A systematic literature search was performed using the Medline database (PubMed). Subsequently, the retrieved literature was selectively reviewed. RESULTS: No published prospective randomized controlled trials have yet addressed the comparison of open and minimally invasive surgery of PCL; however, retrospective case studies have demonstrated the feasibility, safety and a comparable morbidity after minimally invasive distal pancreatectomy (DP), pancreatoduodenectomy (PD), central (CP) or total pancreatectomy and enucleation ...

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 ...

The vast majority of simple hepatic cysts require no treatment. When a cyst is large (greater than 4 cm), it is usually recommended controlling images, for which an ultrasound is usually sufficient. If the cyst does not grow after 2 or 3 years, there is no need for more controls.. In those cases when the cyst is large and symptomatic, treatment is surgery. While there are several surgical options, the most widely used is the unroofing of the cyst, either by open surgery or laparoscopy. The drainage of the cyst by aspiration is not a satisfactory option since the cyst usually recurs.. ...

TY - JOUR. T1 - The first case of primary retroperitoneal mucinous cystadenoma in Korea. T2 - A case report. AU - Min, Byung Wook. AU - Kim, Jong Man. AU - Um, Jun Won. AU - Lee, Eung Seok. 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 ...
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.. ...
Paraovarian/paratubal cysts constitute 5-20% of all adnexal lesions and typically originate from the paramesonephric or Müllerian duct. The primary epithelial tumors arising from paraovarian cysts account for 25% of the cases, but giant cystadenomas of paraovarian origin are extremely uncommon during childhood and adolescence with very few cases reported in the literature. We present the case of a 15-year-old female that presented with a bulky mass in the abdomen and pelvis. An initial clinical and radiological examination indicated an ovarian cyst measuring ∼25x20 cm. However, explorative laparotomy revealed a giant paratubal cyst that was successfully treated with complete excision using fertility-sparing surgery. Histopathological examination was consistent with a serous cystadenoma. The postoperative course was uneventful and the girl was discharged on the seventh postoperative day. At the follow-up of six months, the patient was doing well. Due to their rarity and enormous size, the ...
Answer: Papillary cystadenoma. Histology: The tumor consists of lobules composed of papillary structures lined by cells with abundant to clear cytoplasm. Nuclei appear uniform and small without atypia or mitotic figures. In areas, the tumor is seen projecting within small cystic structures.. Discussion: Approximately 50% of cases of papillary cystadenoma of the epididymis are associated with von Hippel-Lindau disease. Especially in the setting of von Hippel-Lindau disease, the differential diagnosis is between papillary cystadenoma and metastatic renal cell carcinoma as patients with von Hippel-Lindau disease are at increased risk of having renal cell carcinoma. Some cases of papillary cystadenoma are composed of small solid nests of cells separated by a fine, thin vasculature where they can closely resemble renal cell carcinoma. Other areas will show a more papillary configuration with the same clear cytoplasm that is more typical of papillary cystadenoma and would be unusual in clear cell ...
Mucinous cystadenocarcinoma is a type of tumor in the cystadenocarcinoma grouping. It can occur in the breast as well as in the ovary. Tumors are normally multilocular with various smooth, thin walled cysts. Within the cysts is found a haemorrhagic or cellular debris.

Answer: Benign phyllodes tumor. Histology: The prostatic chips are involved with glands showing cystic dilatation. Many of the glands appear somewhat slit-like due to compression by prostatic stroma. In some areas, the stroma protrudes into the cystic space with a polypoid growth. The epithelium lining the cystically dilated prostate glands is benign with an obvious basal cell layer present in many areas. The stroma appears either unremarkable or in other areas more myxoid. The overall stromal cellularity is either normal or hypercellular and lacks cytologic atypia or appreciable mitotic activity.. Discussion: Prostatic cystadenoma could have some of the features seen in this case. However, prostatic cystadenomas are typically extra-prostatic or attached to the posterior prostate by a thin pedicle. Rare intraprostatic cystadenomas occur but can only be diagnosed if there is a localized nodule in an otherwise normal gland. BPH can have focal fibroadenomatous foci yet not to the extent seen in ...
An estimated 22, 000 women are diagnosed annually with ovarian cancer in the United States. Methods: A total of 128 women with unilateral ovarian endometriotic cyst unergoing Laparo-scopic cystectomy were included. Pelvic pain: Ovarian cysts can cause severe pelvic pain before during and after menstruation.. The symptoms of ovarian cysts vary from case to case, although the most common symptoms have been shared by a majority of those with ovarian cysts. When these cysts are twisted by themselves, it is expected to cause painful pain. Nevertheless, sometimes ovarian cyst removal becomes vital.. Occasionally a cyst could rupture (haemorrage) this could course more severe pain, the pain with haemorrhage is more likely to be localised and sharp rather than dull/achey/generalised. If you are diagnosed with a complex ovarian cyst, you need to understand that it is a potentially dangerous condition, and mustnt be ignored.. An ovarian cystadenoma is an abnormal growth that forms from ovarian tissue. ...

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 ...
Images: Cuboidal lining , Glycogen , Aggressive serous cyst , Cysts in serous cystadenomas are composed of a single layer of clear cuboidal cells. These cells usually form flat sheets that line the cysts and only rarely form papillae that project into the cystic spaces. The neoplastic cells have clear cytoplasm because they contain abundant intracytoplasmic glycogen. They do not produce mucin. The nuclei are small, round, and have uniform chromatin and inconspicuous nucleoli. Atypia and mitoses are essentially absent. The central stellate scar and the stroma separating the cysts are composed mostly of relatively acellular collagenous connective tissues, but the stroma may contain entrapped islets of Langerhans and acini. Special stains will highlight the abundant glycogen and absence of mucin. A periodic acid Schiff (PAS) stain will be strongly positive and sensitive to diastase digestion. Stains for mucin, including a mucicarmine and alcian blue stains, will be negative, as will stains for ...
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.
Background: Alpha-smooth muscle actin (α-SMA) is an isoform of actin, positive in myofibroblasts and is an epithelial to mesenchymal transition (EMT) marker. EMT is a process by which tumor cells develop to be more hostile and able to metastasize. Progression of tumor cells is always followed by cell composition and extracellular matrix component alteration. Increased α-SMA expression and collagen alteration may predict the progressivity of ovarian neoplasms. Objective: The aim of this research was to analyse the characteristic of α-SMA and collagen in tumor cells and stroma of ovarian neoplasms. In this study, PCNA (proliferating cell nuclear antigen) expression was also investigated. Methods: Thirty samples were collected including serous, mucinous, endometrioid, and clear cell subtypes. The expression of α-SMA and PCNA were calculated in cells and stroma of ovarian tumors. Collagen was detected using Sirius Red staining and presented as area fraction. Results: The overexpressions of α-SMA in
