A 31-year-old woman with a history of endometriosis was referred to the outpatient colorectal surgery office for evaluation of rectal bleeding. Colonoscopy was recommended because of the ongoing symptoms, and a polyp was discovered in the colon (Fig. 1A). Pathology was consistent with endometriosis (Fig. 1B). The patient was previously scheduled for laparoscopic endometriosis resection and underwent laparoscopic colon resection at the same time. She recovered and continued to do well postoperatively with no additional signs of rectal bleeding.
