We report the case of a 74-year-old woman with a primary mucinous borderline tumor of the fallopian tube coexisting with an ovarian mucinous borderline tumor. Data were obtained through histopathologic study of the excised surgical specimen. p53, estrogen receptor (ER) and PAX8 expression were evaluated by immunohistochemistry on the available right fallopian tube and ovary. Both the ovarian an...

Mucinous tubular and spindle cell renal cell carcinoma is a rare, recently described variant of renal cell carcinoma characterized by an admixture of cuboidal cells in tubules and sheets of spindle cells, and variable amounts of mucinous stroma. It has been recognized as a distinct entity in the 2004 World Health Organization tumor classification. Since then, several dozen of these tumor have b...

A case of mucinous adenocarcinoma arising on a long-standing anorectal fistula is described. A 60-year-old man with a long history of mucinous discharge, pain and perianal induration underwent a biopsy of the external opening of the fistula that showed a mucinous infiltrating adenocarcinoma. Due to the large size of the tumor and the fact that it had extended into the surrounding tissue, preope...

The purpose of this study was to explore the possibility of targeted molecular therapy with anti-epidermal growth factor receptor (anti-EGFR) antibody (cetuximab) for the treatment of mucinous ovarian carcinoma. We analyzed EGFR protein expression and KRAS gene mutations in 5 mucinous ovarian carcinoma cell lines RMUG-L, RMUG-S, MN-1, OMC-1 and MCAS and evaluated the in vitro and in vivo effect...

The PathfinderTG biomarker panel is useful in the evaluation of pancreatic cysts that have clinical features suspicious for malignancy, but its utility in classifying fine-needle aspiration biopsies from small pancreatic cystic lesions is yet to be proven. We used morphology to classify 20 pancreatic cyst cytology aspirates, all of which met radiographic criteria for close observation. Cases we...

The occurrence of malignant mural nodule in benign cystic common epithelial tumor of the ovary have been reported in only three cases; the case one was mucinous cystadenoma with a mural nodule of fibrosarcoma and the others were of carcinomas. Our case was another rare case of ovarian mucinous cystadenoma with mural nodule of anaplastic carcinoma in a 42-year-old woman. The cystadenoma had an u...

An extremely rare case of non-mucinous lepidic-predominant invasive adenocarcinoma (LPA) showing extensive aerogenous spread with a pneumonic presentation is reported. A 73-year-old woman was referred to our hospital because of an infiltrative shadow on chest xray. Chest computed tomography revealed extensive ground glass opacities in the right lower lobe, which was accompanied by infiltrative ...

BACKGROUND Pseudomyxoma peritonei (PMP) is a rare condition characterized by mucinous tumors, disseminated intra-peritoneal implants, and mucinous ascites. So far its diagnosis remains challenging to most clinicians. CASE PRESENTATION A 55-year-old male patient had suffered from acute onset of abdominal pain and abdominal distension for one day prior to his admission. Physical examination rev...

PURPOSE To investigate the antitumor effects of targeting Src and tubulin in mucinous ovarian carcinoma. EXPERIMENTAL DESIGN The in vitro and in vivo effects and molecular mechanisms of KX-01, which inhibits Src pathway and tubulin polymerization, were examined in mucinous ovarian cancer models. RESULTS In vitro studies using RMUG-S and RMUG-L cell lines showed that KX-01 inhibited cell pro...

CONTEXT Heterotopic pancreas is defined as the presence of pancreatic tissue, outside its usual location, which lacks anatomical and vascular continuity with the pancreas proper. Despite the development of modern diagnostic procedures, it is still difficult to differentiate heterotopic pancreas from benign or malignant tumors and other tumor-like lesions. Frozen examination of mucinous lesions ...
