Benign rectal ulcer has been said to be a rare disease. Recently, however, the number of cases of this disease has been on the increase. We have encountered 3 cases of benign rectal ulcer which started with a large volume of bloody stools, presented characteristic clinical pictures and were healed in a short period of time. In two patients, both of whom had cerebrovascular disease as an underlying disease, a mass with ulcer was formed in the lower rectum and healed in a relatively short period of time. Therefore, acute hemorrhagic ulcer of the rectum were highly suspected. The remaining patient with a pacemaker implanted was admitted to the hospital because of pelvic fracture. Multiple aphtoid ulcers developed in the upper rectum and also healed in a short period. The cause was not specified. For bloody stools, endoscopic examination should be performed in order to clarify the site and etiology of the lesion. Also it is important to perform biopsies repeatedly even when cancer is suspected macroscopically from endoscopic examination.
