Disappearance of a sessile tubulovillous adenoma in the rectosigmoid colon during radiation therapy for cervical carcinoma.

: Colonoscopic polypectomy is the usual treatment for an adenomatous colorectal polyp. We report a case of a sessile tubulovillous adenoma in the rectosigmoid colon disappearing during a course of radiation therapy for an unrelated cervical cancer. This case report illustrates that at least some colonic polyps are radiosensitive and can be eradicated during radiation therapy.
