A 67-year old man, who had been diagnosed with cavernous hemangioma of the rectum 2 years before, was admitted to our department presenting with continuous bloody stool. The conservative management approach that had been administered was unsuccessful resulting in repeated hematochezia. During routine colonoscopy it was decided that endoscopic hemostasis was not advisable due to the discolored circumferential mucosal elevation diffusing from sigmoid to rectum. Hemostasis was achieved by abdominaoperineal resection. The resected specimen showed thickening of the intestinal wall, vascular proliferation, and mucosal congestion in the rectum. Histological examination of the tissue revealed diffuse vascular proliferation and aggregation from the submucosa to muscularis propria as well as intravascular calcification. Here we report the diagnosis and treatment of colonic cavernous hemangioma with precise histopathological findings post-surgical treatment.
