Carcinoid tumor of the ampulla of Vater comprises about 2.0-8.9% of the gastrointestinal earcinoid tumors and 3-5.5% of the duodenal tumor. The climcal manifestations of the carcinoid tumor of the ampulla of Vater are jaundice, hemorrhage, obstruction of duodenurn, or carcinoid syndrome. But the symptoms of carcinoid tumor are nonspecific and diagnosis is delayed until far advanced state, usually. Recently we experienced one case of carcinoid tienor in a 33-year-old woman who had epigastric pain and intermittent melena, so we report it with a review of the literature (Korean J Gastroinfest Endosc 11: 67-71, 1997)
