Vascular tumors of the large bowel can be divided into malignant and benign lesions. The benign lesions can be divided into capillary and cavernous hemangiomas. Large-bowel hemangiomas are rare lesions, with the majority of cases reported in the rectum and rectosigmoid regions. Few cases of isolated anal hemangiomas are found in the literature. A case of an asymptomatic anal cavernous hemangioma, palpable on routine rectal examination and subsequently removed at proctosigmoidoscopy, is described.
