 A 76-year-old man with the chief complaint of right hypogastric pain underwent barium enema and endoscopy of the large intestine, which revealed protuberances resembling submucosal tumors around the ostium appendicis vermiformis and small protuberant lesions in the ostium appendicis vermiformis. Although biopsy specimen showed tubulovillous adenoma with moderate atypia, the presence of cancer could not be excluded, and he was treated by ileocecal resection. The lesions were pathologically well differentiated adenocarcinoma in tubulovillous adenoma, and were found to have invaded the wall of the mucosal proper layer. No lymph node metastasis was observed, and the lesions were stage 0.
