We report three cases of pedunculated gastric hamartomatous inverted polyps (HIPs) that were successfully treated by endoscopic polypectomy. The first case involved an 87-year-old woman with mild anemia. Esophagogastroduodenoscopy (EGD) revealed a pedunculated, reddish polyp located at the greater curvature of the upper stomach. The second case involved a 34-year-old woman in whom a pedunculated polyp was found at the gastric fundus during routine EGD. The third patient was a 59-year-old woman with epigastric discomfort EGD revealed a pedunculated polyp in the gastric fundus. Polypectomy was successfully performed in all three cases. Histological examination revealed that the tumors comprised submucosal proliferation of cystically dilated gastric glands and hyperplastic glands; thus, we diagnosed gastric HIPs, which are rare and typically difficult to diagnose. Gastric HIPs should be considered in the differential diagnosis of elevated gastric lesions.
