The purpose of this study was to examine the expression pattern of MUC5AC and SOX2 in ampulla of vater adenocarcinoma and evaluate the association between expression of these gastric epithelial markers and the histologic phenotype of ampulla of vater carcinoma. Six surgically resected samples of ampulla of vater adenocarcinoma, including four intestinal type carcinomas and two pancreatobiliary ...

The duodenum is infrequently affected by malignant lymphoma, and follicular lymphomas of the duodenum are rare histological subtypes. There are no reported cases of collision of follicular lymphoma and other tumors in the ampulla of Vater. A 57-year-old Japanese man presented with jaundice, and abdominal computed tomography revealed a tumor of the ampulla of Vater invading the pancreatic head w...

We report on a two-month-old infant with an unusual form of scimitar syndrome, associated with an absent right pulmonary artery, obstructed inferior vena cava, hemi-azygous continuation and the VACTERL association. The infant posed a major management problem and eventually died from a lower respiratory tract infection.

Signet-ring cell carcinoma (SRCC) of the alimentary canal is a variant of adenocarcinoma that has a poor clinical prognosis. SRCC of the ampulla of Vater is extremely uncommon with < 12 cases reported in the literature. SRCC of the ampulla of Vater occurs in an older age group (mean age 60 yr) when compared to SRCC of the stomach (under 45 yr), but is similar to SRCC of the large intestine. We ...

CONTEXT Signet-ring cell carcinoma (SRCC) of the ampulla of Vater is a very rare clinical entity, which is infrequently reported in medical literature. CASE REPORT A 78-year-old woman was admitted with jaundice, pruritus and postprandial vomiting. Abdominal ultrasound and computed tomography scanning demonstrated gross dilatation of the common bile and pancreatic ducts with gallbladder calcul...
