The patient was a 70-year-old female. She noticed abdominal pain, which was followed by diarrhea and hematochezia on the night of April 1, 2000. She was taken to the emergency department and hospitalized for further examination. Colonoscopy revealed ulceration complicated by edema in sigmoid colon. The ulcerous lesion had spread over the entire circumference of the deeper portion of sigmoid colon. A tumorous lesion of 20 mm in diameter was detected remaining in the normal mucosa within the inflamed mucosa. The tumorous lesion was biopsied and a diagnosis of colon cancer was made. In this case, ischemic colitis was found to accompany colon cancer. The patient was placed on dialytic therapy because of chronic renal failure. A CT scan and X-ray examination revealed marked arteriosclerosis, which was assumed to be responsible for ischemia. A review of literature yielded many case reports on so-called obstructive colitis, ischemic colitis that occurred on the oral side of colorectal cancer. There appeared to be a limited number of cases of colorectal cancer detected at colonoscopy performed to examine ischemic colitis. This rare case was reported in the present study.
