[Primary urethral carcinoma. Epidemiology, diagnosis and pathology. Guidelines from the French Urological Association Cancer committee].

Primary urethral carcinomas are unusual. The most frequent histology is the epidermoid carcinoma in both sex, followed by the urothelial carcinoma in men and adenocarcinoma in women. The diagnosis is often late. It is based on a clinical examination under anesthesia and biopsies. MRI is the best imaging modality for the local stadification.
