چکیده
Signet ring carcinoma is a common type of adenocarcinoma of stomach but its occurrence in ampulla ofVater is extremely rare. There are only a few previous reported cases of signet ring carcinoma of ampullaof Vater. Here we reported a 61-year-old woman with obstructive jaundice. Ultrasonography and computedtomography (CT scan) examination showed intra- and extrahepatic bile duct dilatation. Endoscopicexamination with biopsies revealed a small-size mass in ampulla of Vater with diagnosis of signet ringcarcinoma. On consequent pancreatoduodenectomy the tumor was diagnosed as T2N0M0, stage IB. Becauseof the specific site of signet ring carcinoma of ampulla of Vater, the tumor seems to present itself at anearly stage of disease. We review in the literature to suggest our idea.
