A case of inverted appendiceal stump removed by endoscopic polypectomy was rpeorted. A 34-year-old male was admitted to our hospital because of intermittent lower abdominal pain. Barium enema examination revealed a semipedunculated, oval polypoid lesion of about 10 .times. 15 mm with smooth surface in the postero-lateral area of the cecum. Colonoscopy demonstrated a submucosal tumor covered with normal bowel mucosa at the same site in the cecum. Although inverted appendiceal stump was not completely ruled out, a lipoma was strongly suspected because of the location and the character of the polyp. The tumor was removed by endoscopic polypectomy. Histology of the resected polyp confirmed the diagnosis of inverted appendiceal stump.
