RESUMEN
Carcinoid tumors of the ampulla of Vater are rare. The variant form of ampullary carcinoid tumors containing psammoma bodies is noted extremely rare and produces somatostatin. Obstructive jaundice is the most common presenting symptom of ampullary carcinoid tumor. It is difficult to diagnose ampullary carcinoid tumor preoperatively because of their relatively small size and submucosal location. We report a case of ampullary psammomatous carcinoid tumor and also review the literature. Deep biopsies were taken from the edges of the papillotomy wound of the protruded ampulla of Vater from a 51-year-old man. The histology was consistent with psammomatous carcinoid. 111In-octreoscan revealed an abnormal focal increased radiouptake in the infrahepatic area which suggested the presence of a somatostain producing tumor. The patient underwent a Whipple's operation.
