Mesonephric carcinoma of the female urethra.

Mesonephric carcinoma of the female urethra is rare arising from vestiges of the Wolffian duct and is particularly of gynaecological or urological interest. It has been treated once successfully by radical anterior pelvic exenteration. By more conservative methods of treatment such as transurethral resections, radiation or topical application of thio-tepa it is poorly controlled. The diagnosis is established by a histological pattern reminiscent of the mesonephros.
