Gastric metaplasia of the duodenum, defined as the presence of groups of gastric mucosal cell within normal duodenal epithelium, is an almost constant feature of duodenal ulcer. The pathogenesis of gastric metaplasia is unclear, but acid and Helicobacter pylori infection are contributory factors to the development of gastric metaplasia. Generally, endoscopic finding of gastric metaplasia in duodenum is typically patchy distribution in duodenal bulb, but polypoid gastric metaplasia in duodenum is very rare. We report that the patient who complaints of abdominal pain has a villous, polypoid gastric metaplasia in duodenal bulb without duodenal ulcer. (Korean J Gastrointest Endosc 16: 644~848, 1996)
Key Words: Polypoid gastric metaplasia , Duodenal bulb
