| Abstract: | Cytomegalovirus (CMV) colitis is thought to occur almost exclusively in immunosuppressed persons. Colonoscopy in patients with CMV colitis usually shows diffuse or localized ulceration, although mucosal friability, erosions, hemorrhage, and plaque-like pseudomembranes may be observed. We report on a patient with chronic renal failure undergoing hemodialysis therapy who had abdominal symptoms, including bloody diarrhea, along with colonoscopic findings suggestive of carcinoma of the colon. The patient was not infected with the human immunodeficiency virus and had normal lymphocyte subset numbers. He was subsequently found to have invasive CMV disease of the colon. CMV colitis can occur in persons who are not severely immunosuppressed, and its colonoscopic appearance may mimic that of colon cancer. |
