We describe here a rare case of nodule‐aggregating lesion of the terminal ileum detected by colonoscopy. An 82‐year‐old Japanese woman was admitted to our hospital with diarrhea. Colonoscopy revealed a flat elevated tumor with conglomerated nodular surface involving the entire circumference of the terminal ileum, suggesting a nodule‐aggregating lesion. Magnifying the colonoscopic view showed the branch‐like or gyrus‐like pits. On biopsy, the tumor was diagnosed as a tubulovillous adenoma. Retrograde ileogram using a colonoscope revealed an elevated tumor with nodular irregularity, measuring 5 cm in length. Ileocecal resection was performed. Macroscopically, the tumor in the terminal ileum, 8 cm distant from the ileocecal valve, showed a nodule‐aggregating lesion, measuring 44 × 60 × 6 mm in size. Histologically, the tumor showed a focal carcinoma in tubulovillous adenoma. To our knowledge, this is the fifth case of early cancer of the ileum in Japan, and the first case of nodule‐aggregating lesion of the ileum detected by colonoscopy in the world.
