We herein report a rare case of ileal adenocarcinoma that was completely removed by endoscopic submucosal dissection (ESD) without any complications. An 80-year-old man was referred to our hospital to undergo treatment for an ileal tumor. Conventional colonoscopy showed a reddish depressed lesion that was classified as type 0-IIc according to the Paris classification. The ileal tumor was successfully removed en bloc by ESD with a negative surgical margin. The histological findings showed a well-differentiated adenocarcinoma with no submucosal or lymphovascular invasion. Colonoscopy and CT performed one year after ESD showed no local recurrence, stenosis, or lymph node metastasis.
