title: Unusual manifestation of an ampullary tumor presenting with severe upper gastrointestinal bleeding.
abstract: Ampullary tumors can occasionally ulcerate and present as frank gastrointestinal bleeding. The most common clinical presentation is jaundice like in other tumors of the biliary tree. We report on a 68-year-old man who presented with severe upper gastrointestinal hemorrhage secondary to an asymptomatic mass of the ampulla of Vater. An endoscopic biopsy specimen revealed a villous adenoma with moderate dysplasia. A curative resection was performed, and pathological work-up revealed the presence of an infiltrating, moderately differentiated ampullary adenocarcinoma.
