Colitis quística profunda posradioterapia: Caso clínico / Colitis cystica profunda: Report of one case

Colitis cystica profunda is a benign condition that can be confused with adenocarcinoma. We report a 35year-old woman that received radiotherapy for a uterine cervical carcinoma who presented intermittent hematochezia three times after ending the therapy. This episode was diagnosed and treated as a radiation colitis and the patient remained asymptomatic for six years. After this period she presented again intermittent hematochezia and a rectal mass that was surgically removed. The pathology report disclosed a colitis cystica profunda.
