Gastric submucosal ectopic glands are not infrequently encountered in the examination of resected stomach. It is extremely rare for these lesions to have a definite stalk. We have experienced such a case with Yamada's Type III elevated lesion which was removed by endoscopic polypectomy with high frequency and confirmed by histopathological examination of the polypectomized specimen. Therefore, this case seems to be worth recording. A 70-year-old woman visited a local medical doctor because of anorexia. Upper gastrointestinal series revealed an abnormality and she was referred to our department and admitted for further check-up of it. X-ray and endoscopic findings showed a Yamada's Type III elevated lesion, 13 × 16 mm in size with an ulcer at the top on the posterior wall of the gastric antrum. It was diagnosed as a gastric submucosal tumor and endoscopic polypectomy with high frequency was performed. Gastric submucosal ectopic glands were confirmed by histopathological examination of the polypectomized specimen.
