Diagnosis of an unusual tumor in the duodenum

Abstract

A 65-year-old patient was admitted with repeated vomiting and suspected upper gastrointestinal bleeding. He had a known history of acute bleeding of an ulcer of the ileocoecal region, which had to be treated surgically. An esophagogastroduodenoscopy demonstrated a gastric ulcer (Forrest III; Helicobacter pylori negative), and Mallory-Weiss lesions covered with fibrin, with hemorrhagic reaction of the surrounding tissue; there was no sign of acute bleeding. Furthermore, a polyp in the duodenal bulb was seen (Figure [1]), which was considered to be of inflammatory origin. Multiple biopsies were taken.
