Diffuse cavernous hemangioma of the rectosigmoid and low anterior resection using the autostapler.

Over 200 cases of colonic hemangioma have been reported, with more than 50% occurring in the rectosigmoid. These benign vascular neoplasms usually present in childhood, often with life-threatening hemorrhage. Lack of awareness of the condition continues to lead to errors in diagnosis and management, and may contribute to previously reported mortality rates of 50%. We report a case of diffuse cavernous hemangioma of the rectosigmoid in a 10-year-old boy and its treatment by low anterior resection using the end-to-end autostapler.
