title: Colitis cystica profunda lokalisata.
abstract: A 33-year-old man had a three-year history of ulcerative colitis. After 14 months of treatment he developed localized colitis cystica profunda mimicing a stenosating cancer of the rectum. The process developed over a short period. The diagnosis is based on a histological examination revealing benign submucosal cysts lined by columnar epithelium. A conservative surgical attitude is recommended.
