[Prostatic involvement in leukemia. Report of a case].

Infiltration of the prostate is frequent in the course of leukaemia. It is usually asymptomatic or may present in the form of classical bladder neck obstruction. The diagnosis is generally established during investigation of benign prostatic hypertrophy by biopsy or during treatment by resection. Treatment of leukaemia by systemic chemotherapy is unable to sterilize the prostatic site and must therefore be combined with local radiotherapy.
