Capillary hemangiomas of the rectum are rare, especially small capillary hemangiomas. We experienced a case of small capillary hemangioma of the rectum, about 2mm in diameter, presenting with massive bleeding.<br> A 51-year-old woman was seen at the hospital because of massive rectal bleeding. There was a previous history of having an internal hemorrhoid. It was difficult to stop the bleeding and an emergency operation was carried out. During the operation we found a white small elevated lesion of about 2mm in diameter locating about 1cm oral side from the dentate line and arterial bleeding from its center. The elevated lesion was excised and sutured.<br> The excised lesion revealed nodular growth pattern of papillary vessels. It was pathologically diagnosed with capillary hemangioma.
