title: Torrential rectal bleeding. An unusual presentation of colonic carcinoma.
abstract: A case of torrential rectal bleeding due to a colonic carcinoma is reported. The clinical diagnosis was confirmed by angiography, which showed an abnormal circulatory pattern at the hepatic flexure of the colon. Resection of the tumour controlled the bleeding. Dealing with this clinical problem requires a systematized approach. Angiographic demonstration of the source of the bleeding allows definitive surgical management.
