Hemangioma of the rectum: clinical appearance and treatment.

A 53-year-old woman who had severe rectal bleeding was found to have a perirectal hemangioma as a source of the bleeding. Four years prior to this admission, she had undergone, in another hospital, hemorrhoidectomy, which had required resuturing several times in order to stop rebleeding. The diagnosis of hemangioma was established after extensive roentgenographic examination. The patient was treated with low-dose irradiation, divided into five consecutive sessions, to the affected area. The bleeding stopped, and the patient has been free of disease since treatment two years ago. The lumen of the rectum is not narrowed, the mucosa appears normal, and the elasticity of the rectal wall has been preserved.
