Abstract

In Japan, only 7 cases of intestinal endometriosis diagnosed by colonoscopic biopsy have been reported. We here report a case of rectal endometriosis diagnosed by biopsy. The case was 36-year-old female who was admitted to our hospital complaining of hematochezia and lower abdominal pain during menstrual period. Colonoscopy revealed a submucosal tumor with multiple reddish granules in the rectum. Biopsy specimens from the reddish granules revealed endometrial tissue in the mucosa. We treated the patient with danazol 400 mg per day for 3 months, and confirmed the reduction of the submucosal tumor by colonoscopy.
