A 62-year-old man was admitted to our hospital because of dyspnea. He was proved to have HIV antibody. After admission, a large amount of anal bleeding appeared. Colonoscopy performed on the next day showed a large amount of blood, multiple erosions and ulcers in the entire colon and rectum.
The varioliform erosions that were characteristic in amoebic colitis and punched out ulcers were also observed. Biopsy was performed from the ulcer bottom, and its specimen revealed Entamoeba Histolytica (trophozoites) in the necrotic tissue. Soon after the tretment with metronidazole, anal bleeding disappered. On colonoscopy performed one month after the treatment ended, erosions and ulcers improved.
Because of the underlying disease and the various endoscopic findings of this case, a differential diagnosis was needed, especially with regard to cytomegarovirus colitis. A further comparative study of endoscopic findings of colitis seen in AIDS patients is needed.
