title: Benign melanosis and malignant melanoma of penis and male urethra.
abstract: Malignant melanoma of the penis and male uretha are unusually aggressive tumors which only rarely are cured by radical surgery. Melanosis of the penis may be confused with malignant melanoma, and we report a case of melanosis originally diagnosed and treated as melanoma with survival for twenty years. We contrast this with another case of malignant penile melanoma with a fatal outcome.
