Mucinous adenocarcinoma of the prostate is rare and its biological behavior is not well known. We report a case of mucinous adenocarcinoma of the prostate, which was treated successfully with castration. Positivity for prostatic specific antigen by immunohistochemistry confirmed the prostatic origin of this tumor. A review of the literature revealed 30 authentic cases. Prostatic mucinous adenoc...

The authors report a case of mucinous carcinoma of the male breast firstly diagnosed as a mucinous carcinoma of the skin. The immunohistochemical results of this tumor were as follows: cytokeratin7 (-), gross cystic disease fluid protein 15 (-), p63 (-), estrogen receptor (+), and progesterone receptor (+) for the primary nodule; cytokeratin7 (-), thyroid transcription factor-1 (-), gross cysti...

Metastatic mucinous adenocarcinoma of appendix origin and mimicking a gastric subepithelial tumor (SET) is very rare. Endoscopic ultrasound (EUS)-guided sampling is a useful diagnostic method for SETs. However, the cytologic findings of metastatic mucinous adenocarcinoma are unfamiliar to many pathologists and gastroenterologists. These findings present a diagnostic challenge because the introd...

BACKGROUND Primary retroperitoneal mucinous cystadenoma of borderline malignancy represents a rare tumor, with unclear histogenesis, concerning almost exclusively women. Only two cases concerning male patients have been reported. CASE REPORT We herein report a case of a 37 year old man undergone laparotomy for a sizable retroperitoneal tumor resulting after the histological examination to a p...

OBJECTIVE Some molecular and histological evidence suggests that mucinous epithelial ovarian cancers develop via a sequence from benign tumor through borderline tumor to invasive cancer. Such a sequence would predict some shared risk factors between the different tumor types. To investigate this, we examined risk factors for benign, borderline and invasive mucinous ovarian tumors. METHODS A p...

Bleeding per rectum is a common complaint in pediatric age group and mostly relates to benign conditions. Underlying colorectal carcinoma is a rare cause and carries a poor prognosis. We report two cases of mucinous adenocarcinoma of colon, one in a 9 years old male and other in a female of 12 years. The boy presented with rectal bleeding and increasing constipation of more than three years dur...

BACKGROUND Mucinous carcinoma (also known as colloid carcinoma) is a particular type of breast cancer characterized by the presence of extracellular mucin and is linked with a more favorable prognosis than invasive breast carcinoma of no special type. Mucinous carcinoma of the breast is an uncommon form of breast tumor, often presenting as a lobulated, moderately well circumscribed mass on mamm...

CONTEXT We herein present a rare case of a mucinous cystic neoplasm of the pancreas producing CA 19-9 and the clinical implications are discussed. CASE REPORT A 35-year-old woman with no history of abdominal surgery presented at Saisei Kai Sendai Hospital with an upper abdominal distention. Abdominal CT showed a large lobulated cystic tumor at the pancreatic tail. No distant metastases were i...

Vermiform appendix torsion is rare, and even more uncommon is the volvulus of appendiceal mucinous tumors. To our knowledge, only nine cases of torsion of the vermiform appendix associated with appendiceal mucinous neoplasms have been reported up to date. We report a case of secondary torsion of the vermiform appendix with mucinous cystadenoma in a 30-year-old man. The symptoms were consistent ...
