Abstract
A 55-year-old man and a 76-year-old woman were referred to our hospital due to a gastric polyp. In both cases, gastroendoscopy revealed a pedunculated polyp measuring 20mm in diameter at the gastric body. The surfaces of these polyps appeared to be normal with slight depressions. Endoscopic polypectomies were performed. Histopathological examinations established the diagnosis of gastric hamartomatous inverted polyp, which appeared as inverted growth of mucosa and muscularis mucosa into the submucosal layer. Gastric hamartomatous inverted polyps are rare, and most of them have the appearance of submucosal tumors. The pedunculated growth appearances as observed in the two cases are very rare. Herein, we report two cases of pedunculated gastric hamartomatous inverted polyps.
