Abstract
We report an interesting case of unclassifiable multiple rectal ulcers with variegated endoscopic findings. A 65-year-old man with liver cirrhosis and diabetes mellitus was admitted to our hospital complaining of anal bleeding. Physical examination revealed severe edema of the scrotum and perianal area. Endoscopic examination of the rectum on admission revealed severe edema and multiple circumferential bleeding ulcerations with variegated endoscopic findings at 3 to 15 cm from the anal ring. Ten days later, those ulcerations severely extended and mucosal bridge formation was found in some portions. These lesions were improved quite slowly by conservative therapy, whereas there remained some shallow depressions covered with regenerative tissue and mucosal bridge. During the course, rectal biopsy specimens taken at 7 times of endoscopic examination (total 39 spots), did not show any specific inflammatory change. This case obviously differes from the other established diseases and seems to be very interesting.
