title: [Rectal stenosis caused by cancer of the prostate: difficulties of diagnosis].
abstract: There exist rare cases in which a prostatic carcinoma invades the perirectal space producing an extrinsic rectal stenosis. Three cases are discussed. Differential diagnosis with a rectal tumor is difficult clinically, but deep rectal biopsies will provide the correct diagnosis in many cases. Estrogen therapy is recommended, but prognosis is reserved.
