Mucinous noncystic (colloid) carcinoma (MNCC) of the pancreas is considered an uncommon variant of ductal adenocarcinoma of the pancreas with specific histopathological and molecular features. We report the CT findings of large area of hypoattenuation and intratumoral calcification in a pathologically proven case of mucinous non-cystic carcinoma of the pancreas. MNCC of the pancreas is a distin...

Mucinous adenocarcinoma of the prostate gland is one of the least common morphologic variants of prostatic carcinoma. A lack of precision in the definition of these mucinous neoplasms has resulted in reports which have overstated the incidence of this lesion. Of approximately 1,600 carcinomas of the prostate gland seen at Memorial Hospital from 1963 to 1983, excluding cases with only needle bio...

This study has analyzed the gene expression patterns of an IPMN microarray dataset including normal pancreatic ductal tissue (NT), intraductal papillary mucinous adenoma (IPMA), intraductal papillary mucinous carcinoma (IPMC), and invasive ductal carcinoma (IDC) samples. And eight clusters of differentially expressed genes (DEGs) with similar expression pattern were detected by k-means clusteri...

Metastatic breast carcinoma is rarely seen in clinical practice. It has been reported that lymphoma-leukemia, melanoma and sarcomas can metastasize to the breast. Bilateral metastases to the breast are rare and commonly have been seen to originate from ovarian carcinoma. Adenocarcinoma of rectum metastasizing to breast is an extremely rare clinico-pathological situation. We report a 28-year-old...

BACKGROUND Reports of neoplasms in Panthera species are increasing, but they are still an uncommon cause of disease and death in captive wild felids. The presence of two or more primary tumor in large felids is rarely reported, and there are no documented cases of ocular melanoma and mammary mucinous carcinoma in African lions. CASE PRESENTATION An ocular melanoma and a mammary mucinous carci...

Large cell neuroendocrine carcinoma (LCNEC) of the ovary is a rare entity and is frequently associated with ovarian surface epithelial tumors. Since Collins et al. described the fi rst case of mixed neuroendocrine and mucinous carcinoma, a few more cases of primary ovarian LCNECs have been reported. The prognosis of LCNECs is generally very poor even when the diagnosis is made at an early stage...

Introduction: Alpha-methylacyl-CoA-racemase (AMACR) is a tumor marker expressed in prostate cancer. Literature data concerning its expression in different variants and unusual patterns of prostate carcinoma are uneven and less numerous. The present study investigates the AMACR expression in some rare forms of prostate carcinoma. Material and methods: Distinct variants and unusual patterns of pr...
