ABSTRACT

Radiotherapy induced colorectal adenocarcinoma with radiation colitis after radiotherapy has been reported as a rare case. A patient with rectal adenocarcinoma as a late complication of pelvic irradiation for gynecological malignancy is reported. A 55-year-old woman with bloody diarrhea for 6 months was admitted. She received radiation therapy for carcinoma of cervix 21 years ago. Colonoscopic findings revealed a polypoid mass on rectosigmoid colon. Histopathologic examination of the polypectomy specimen disclosed adenocarcinoma. We reported herein a case of rectal adenocarcinoma with radiation colitis. The patient who had received pelvic irradiation should have close follow-up with colonoscopic study for the early detection of colorectal cancer.
