A CASE OF ACUTE RECTAL MUCOSAL LESION WITHOUT BASIC DISEASE AND INDUCEMENT IN THE BACKGROUND

Abstract

A 65-year-old male patient complained of fresh melena. He became completely blind because of bilateral cataract at 33 years old. On May 25, 1989, the patient had a cup of melena. Hemorrhage recurred twice after initial evidence and he was hospitalized. Hematological examination revealed anemia, showing Hb value 10.3 g/dl. Colonoscopy disclosed two irregular ulcers with visible blood vessels at 5 cm from the anal ring. Longitudinal ulcer was formed on the oral side in one lesion. Hemorrhage was stopped with conservative treatment. Ulcer developed scar formation on the 14th hospital day. This case is not acute hemorrhagic rectal ulcer proposed by Kohno et al. since there were no severe basic diseases or inducements in the background. However, elucidation of the mechanism of these acutery developing rectal ulcer lesions is expected, and we would like to propose to deal with such lesions collectively as acute rectal mucosal lesions.
