Abstract

An adenomyoma is a rare, benign tumor, characteristically composed of a mixture of glandular structures with intervening bundles of smooth muscle. An adenomyoma is considered to be a variant of an ectopic pancreas, without exocrine or endocrine components. Adenomyomas of the gastrointestinal tract are found most frequently in the stomach and the small intestine is rarely involved. Gastric adenomyoma is frequently localized in the antrum or pylorus and very rarely occurs in the body. Adenomyomas often appear as a submucosal mass. A 48-year-old man was referred for further management of a 2.5-cm pedunculated polyp in the stomach. The resected tumor was diagnosed as an adenomyoma of the stomach. To the best of our knowledge, this is the first case reported in the literature of gastric adenomyoma that presented as a pedunculated polyp in the body and was treated completely with endoscopic resection.
