A 20-year-old male patient was admitted to our hospital complaining of abdominal pain and muco-bloody stool. By physical examination, the ileocolic intussusception was suspected and confirmed by barium enema. Symptoms were relieved by complete reduction by high barium enema. By the endoscopic examination performed late, a none-peduculated polypoid lesion was revealed at the splenic flexure beside the lymphoid hyperplasia at the terminal ileum. The shape of the polypoid lesion varied easily by the change of patient's position or compression by washing pipe. It's surface was smooth and glossy. The presumptive diagnosis of lymphangioma was made from these clinical findings and the endoscopic polypectomy was carried out. The removed specimen was a 1.2×1.1×0.8cm sized lymphangioma. Lympangioma is a rare bengin lesion in the large intestine. Forty two cases of the colonic lymphangioma including our case have been reported in Japan. The endoscopic polypectomy was performed in only of these 42 cases. The endoscopic polypectomy seems to be preferable procedure for colonic lymphangioma considering the pathologic character of tumor.
