Primary malignant melanoma of the female urethra.
A case of primary urethral malignant melanoma of a 69-year-old Japanese woman is presented. A hemorrhagic tumor measuring 1 cm in diameter was diagnosed by the stamp method. Clinically, the primary lesion was a T4 tumor infiltrating to the bladder neck, vagina, and vulva. Computed tomography did not detect any inguinal lymph node swelling or metastases to other sites. We selected radical extirpation, including cystectomy, ureterostomy, and bilateral inguinal and pelvic lymph node dissection. Although she subsequently underwent immunochemotherapy, consisting of dacarbazine, nimustine, vincristine, and beta-interferon, she died of the cancer 14 months postoperatively.
