The 20th case of primary malignant melanoma of the female urethra in the Japanese literature is reported. An 86-year-old woman presented with urethral bleeding. A hemorrhagic cheery-sized mass was identified at the urethral meatus, which extended into the vaginal mucosa, and was diagnosed as malignant melanoma after biopsy. Surgical treatment was abandoned because she had dementia and bilateral inguinal lymphadenopathy. She had no symptoms during the following 4 months.
