primary retroperitoneal mucinous tumor (prmt) of low malignant potential (border line) is an uncommon neoplasm with fewer than 50 reported cases. uncertain diagnostic imaging results make diagnosis of its origin difficult, preoperatively. later treatment planning and prognosis would be affected by exact diagnosis of the tumor origin. this study presents a case of persian woman with diagnostic, ...

UNLABELLED Mucinous cystadenomas are relatively uncommon benign cystic tumors. Most of them are found in the ovary, pancreas, and appendix. Primary mucinous cystadenoma of spleen is extremely rare and only countable cases have been recorded. These are assumed to arise from heterotopic pancreatic tissue or invaginated spleenic capsular mesothelium. We present a rare case of primary mucinous cyst...

Mucinous metaplasia of the genital area is a rare condition characterised by the emergence of mucin containing cells in stratified squamous epithelium. This report describes a unique case of benign mucinous metaplasia of the vulva associated with lichen sclerosus in a 60 year old woman. Histopathology revealed cervical type metaplasia with otherwise typical lichen sclerosus. This report discuss...

Primary renal mucinous cystadenocarcinoma is a very rare lesion of kidney which originates from the metaplasia of the renal pelvic uroepithelium. Only one case with primary mucinous cystadenocarcinoma has been reported in the English literature. We report second case of mucinous cystadenocarcinoma which was radiologically classified as type-IIF Bosniak cyst in peripheral localization. We aimed ...

Primary mucinous cystadenomas are rare retroperitoneal tumors that are exclusively found in women. The histogenesis of these tumors is still uncertain, though mucinous metaplasia of the mesothelial lining cells is the most likely hypothesis. We report a 19-year-old pregnant female, initially believed to have a severe hydronephrosis of left kidney, but was finally diagnosed as a retroperitoneal ...

Colorectal cancer is rare in teenagers, especially without known risk factors. Colon cancer in young age is more likely to be diagnosed at advanced-stage, to present unfavorable tumor histology such as mucinous carcinoma, and poor outcome. We report a case of sporadic mucinous adenocarcinoma of the colon in a 19-year-old male patient without any risk factors. He complained of severe left abdomi...

For intraoperative consultation of mucinous adenocarcinoma involving the ovary, it would be useful to have approaching methods in addition to the traditional limited microscopic findings in order to determine the nature of the tumors. Mucinous adenocarcinomas involving the ovaries were evaluated in 91 cases of metastatic mucinous adenocarcinomas and 19 cases of primary mucinous adenocarcinomas ...

Mucinous epithelial ovarian cancers are clinically and morphologically distinct from the other histopathologic subtypes of ovarian cancer. Unlike other ovarian subtypes, epidemiologic studies have indicated that tobacco exposure is a significant risk factor for developing mucinous ovarian cancer. Detection of autoantibody reactivity is useful in biomarker discovery and for explaining the role o...

Pancreatic cystic lesions (PCL) may be incidentally detected in up to 13.5% of patients. These represent a wide variety of lesions including mucinous cysts [intraductal papillary mucinous neoplasms (IPMN) and mucinous cystic neoplasms (MCN)] that have malignant potential. The difficulty in identifying the various PCL and their unpredictable potential for malignant degeneration makes their manag...

Various mucin-producing neoplasms originate in different abdominal and pelvic organs. Mucinous neoplasms differ from non-mucinous neoplasms because of the differences in clinical outcome and imaging appearance. Mucinous carcinoma, in which at least 50% of the tumor is composed of large pools of extracellular mucin and columns of malignant cells, is associated with a worse prognosis. Signet ring...
