Ampullary tumors represent a various group but uncommon lesions located at the confluence of the pancreatic and bile ducts. They account for 1 to 2% of the digestive tract tumors, they may be benign and malignant. Among benign tumors, the adenoma is the most common and its incidence ranges from 0.04 a 0.12%. They can be sessile or pedunculated and histologically differentiated tubular, tubulo villous and villous. Because of its malignant potential, the recommended treatment is surgical resection or endoscopic either, the latter indicated in tumors less 4.5 cm. A case of 78 years old male patient who consulted with jaundice, abdominal pain and two months weight loss. It performed abdominal ultrasound and CT reporting in confluent biliopancreatic solid image. Duodenoscopy was performed finding ampullary tumor six inches diameter appearance fluffy. Considering patient age and comorbidities, it decided parcel endoscopic ampullectomy. In endoscopic retrograde cholangiography, defect image was observed in distal choledochal, so we proceeded to extract with Fogarty Balloon, giving pedunculated villous tumor, which is removed without complications. The histopathological finding was tubule villous adenoma, with low grade dysplasia. In endoscopic and histologycal controls up to procedure ten months, is not clinically evidence tumor recurrence and the patient is asymptomatic in good general conditions.
