Four cases of acute hemorrhagic rectal ulcer were reported. All patients were aged and/or incapable of standing. All cases had sudden onset of fresh anal bleeding without pain. Local injection of ethanol absolute was needed in one case. In three cases, ulcers healed with improvement of the general condition, but one was dead due to renal failure. Ulcers occupying one third to all circumference of the rectum were broad, serpiginous and multiple from the dentate line to 5 cm portion in three cases. One case had a round ulcer on 10 cm portion from the dentate line. It is suspected that the stress due to the lesions in the central nervous system is related to the formation of acute hemorrhagic rectal ulcer, because patients with cerebral vascular diseases sometimes have this disorder. In patients at poor risk or incapable of standing, such lesion is also found. The differential diagnosis between acute hemorrhagic rectal ulcer and solitary ulcer of the rectum is possible in the factors of histological and endoscopic findings.
