INTRODUCTION Primary retroperitoneal mucinous cystadenoma is a rare tumor prevailing specifically in female gender. Its histogenesis is still unclear and its diagnosis is mainly based on morphological characteristics. CASE PRESENTATION the subject is a 44 years old man presenting an abdominal pain on the right side, with a palpable mass which appeared four months ago. Abdominal ultrasound (ec...

Tumor associated antigen present in the cyst fluid of a patient with papillary mucinous cytadenocarcinoma of the ovary was prepared by ammonium sulfate precipitation. The dialyzed precipitate was emulsified in complete Freund's adjuvant and injected into rabbits followed by booster doses of the antigen in saline. The resulting antiserum was absorbed with normal human serum and normal liver and ...

Mucinous carcinoma is a type of ductal carcinoma with a low malignant potential. These tumors account for 2% of the breast carcinomas. These neoplasms are characterized by tumor cells floating in the pools of mucin. The prognosis of pure mucinous carcinoma is favourable when compared to the invasive ductal carcinoma, not otherwise specified. We report a case of 80years female patient presenting...

Primary cutaneous mucinous carcinoma is a rare malignant tumor that originates from the deepest portion of the eccrine sweat duct. Common sites of involvement are the face and scalp. Biopsy shows dermal epithelial cell islands embedded in mucin pools separated by fibrous septae. It is difficult to differentiate this tumor histologically from metastatic adenocarcinoma. Recurrence after excision ...

Ovarian fibroma is the commonest benign tumor of the ovarian stroma. The cellular subtype accounts for around 10% of ovarian fibromatous tumors. The cellular fibroma is a tumor of uncertain malignant potential that may recur or be associated with peritoneal implants. Usually these are solid tumors, sometimes with small areas of cystic degeneration. This case is reported to highlight an unusual ...

Primary ovarian large cell neuroendocrine carcinoma (LCNEC) is a rare tumor with a very poor prognosis and is included in the miscellaneous group category of the World Health Organization tumor classification. Most of these tumors are associated with other epithelial neoplasm. To the best of our knowledge, 30 cases have been reported in the English literature. LCNEC associated with a pure mucin...

Pseudomyxoma peritonei (PMP) is a rare disease that usually originates from mucinous neoplasms of the appendix and, less commonly, from extra-appendiceal tumors, but it may also be caused by synchronous primary mucinous tumors of the ovary and appendix. The current study discusses the case of a 73-year-old female who presented with progressively worsening indigestion and abdominal distension. M...

Using a double-antibody panning procedure, we separated a unique cancer antigen cell line (BS-SHI-4M OVC-MU) expressing a mucinous ovarian cancer (OVC) antigen from a malignantly transformed Bloom's syndrome cell line. In order to gain information concerning a mucinous OVC antigen, we tested this unique cell line in the reaction to sera from patients with various OVCs, Krukenberg (KR) tumor, an...

Intraductal papillary neoplasm associated with mucinous ductal ectasia is an uncommon cystic disease of the pancreas. This tumor is characterized by the multilocular cyst lined by mucin producing cells with variable degrees of atypia and ductal ectasia. In addition, this tumor has a favorable prognosis in contrast to other mucinous cystic tumor of the pancreas. Reports on intraductal mucin prod...
