A review is made of 36 carcinomas of the penis treated in the Urology Department of the "La Fe" Hospital. The most frequent decade for their appearance is the fifties. We establish their link with restricted hygiene and with fimosis, Queyrat's erythroplasia, leukoplasia and accuminated condyloma. The treatment given depends essentially on the clinical stage. We feel that within stage A, with minimum prepuce lesions, the ideal treatment is local excision and circumcision plus radiotherapy; in the case of minimal gland lesions radiotherapy; in the rest and when the former forms of therapy fail, partial amputation of the penis. We currently treat this stage with cryosurgery although we cannot give any results because of the limited period of development of the same. In stage B, we indicate amputation plus bilateral, ilio-inguinal lymphadenectomy plus radiotherapy. In stages C and D the treatment is palliative, on the basis of polychemotherapy.
