Primary adenocarcinoma of the male urethra is very uncommon, accounts for 5% of primary urethral cancers. All types of urethral carcinomas account for less than 1% of urinary malignancies in man. The prognosis remains poor despite the wide surgical treatment. The place of chemotherapy combined with radiotherapy must be defined by other studies. We report a case of primary locally advanced adenocarcinoma arising in the bulbo-membranous urethra. The patient was 29 years old, without any previous history of venerian disease. He was treated by combined external beam radiotherapy (total dose 67Gy) and chemotherapy (Cisplatinum). A marked reduction of tumor volume has been noted but the patient died because of the appearance of bone metastasis which failed to the systemic therapy.
