title: [A case of giant Brunner's gland hyperplasia combined with adenomyomatous hyperplasia].
abstract: Brunner's gland hyperplasia is a rare tumor of the duodenum and might also be an unusual cause of gastrointestinal bleeding. In symptomatic patients, treatment requires either surgical resection or endoscopic polypectomy. We report a case of upper gastrointestinal bleeding from a pedunculated Brunner's gland hyperplasia in the duodenal bulb. Endoscopic resection using the detachable snare and hemoclipping was instituted to remove a large pedunculated polyp. The pathologic diagnosis was Brunner's gland hyperplasia with adenomyomatous hyperplasia.
