title: Hemangiosarcoma of the rectum after chronic anorectal ulceration.
abstract: A 37-year-old man with a 30-year history of recurrent anorectal ulceration developed a hemangiosarcoma of the rectum. This diagnosis was made based on histology and immunocytochemistry. We believe this is the fifth reported case of hemangiosarcoma of the rectum and is another example of a rare granulation tissue sarcoma.
