A CASE OF PEDUNCULATED HAMARTOMATOUS INVERTED POLYP OF THE STOMACH TREATED BY ENDOSCOPIC POLYPECTOMY

Abstract

We report a case of hamartomatous inverted polyp which grew with a peduncula in the cardiac portion of the stomach. A 75-year-old woman was admitted for further examina tion and treatment of an elevated lesion of the stomach. For the purpose of total biopsy, endoscopic polypectomy was performed after snaring the base of the stalk with detachable snare. Histological examination of the polypectomized specimen showed gastric gland with cystic dilatation in the submucosal layer. This was a rare case that a group of ectopic gastric glands was pedunculated and polypectomized endoscopically.
