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 a...

BACKGROUND Mucinous cystadenomas of the liver are rare cystic neoplasms. The aim of this study was to assess management of a consecutive series of patients who underwent laparotomy for a suspected cystadenoma or cystadenocarcinoma. Secondly, the origin of ovarian stroma (OS) in mucinous liver cystadenomas was examined during early embryonic development. PATIENTS AND METHODS Patients diagnosed...

BACKGROUND As in ulcerative colitis, there is an increased incidence of colorectal carcinoma in Crohn's disease. While carcinoma formation originating from ano-rectal fistulas is generally considered as a rare event there are different publications reporting on mucinous adenocarcinoma formation in association with a neovagina and rectovaginal fistulas. To the best of our knowledge this is the f...

BACKGROUND Ovarian mucinous carcinoma has a poor prognosis in advanced stages and a poor response to conventional chemotherapy. An efficient treatment is not yet available. We heere investigated HER2 expression and the potential for trastuzumab therapy in ovarian mucinous tumors. MATERIALS AND METHODS Immunohistochemistry was performed in formalin-fixed, paraffin-embedded tissue from 27 ovari...

We report a case of a primary intratesticular mucinous cystadenoma in an asymptomatic 39-year-old man. The mass was found incidentally during a consultation for infertility. Pathologic examination of the orchiectomy specimen revealed a unilocular cyst lined with bland mucinous epithelium and mucinous extravasation, consistent with a diagnosis of mucinous cystadenoma. Foci of bone were also foun...

We describe here a 67-year-old man who was diagnosed with a rare case of intraductal papillary mucinous tumors that occurred simultaneously in the liver and pancreas. Abdominal computed tomography showed a tubular and cystic dilatation of the pancreatic duct in the pancreas tail, which suggested an intraductal papillary mucinous tumor (IPMT), and multiple intrahepatic duct stones. The patient u...

The real prevalence of pancreatic cystic lesions remains unknown. The malignant potential of some of these lesions remains a cause for significant concern. Thus, it is mandatory to develop a strategy to clearly discriminate those cysts with a potential for malignant transformation from those that do not carry any significant risk. Intraductal papillary mucinous neoplasms and mucinous cystadenom...

Primary mucinous adenocarcinoma is an extremely rare type of bladder cancer, with aggressive behavior and poor response to chemotherapy and radiotherapy. The symptoms are similar to those of other bladder tumors. Surgery is the main treatment and remains the only curative option. There may be a progression from mucinous metaplasia to mucinous adenoma and then mucinous adenocarcinoma. We present...

INTRODUCTION Mucinous tumors are the second most common form of epithelial ovarian tumor, yet the cell of origin for this histologic subtype remains undetermined. Although these tumors are thought to arise through a stepwise progression from benign cystadenoma to borderline tumor to invasive carcinoma, few studies have attempted to comprehensively characterize the genetic changes specific to th...

CONTEXT Cystic neoplasms, which are less common forms of exocrine pancreatic neoplasms, consist of mainly intraductal papillary mucinous neoplasms (IPMN) and mucinous cystic neoplasms. Mucinous cystic neoplasms, unlike IPMN, are not associated with ductal growth, are usually multilocular in nature, and have ovarian type stroma. Mucinous cystadenocarcinoma is a type of mucinous cystic neoplasm m...
