A 69-year-old male patient visited our clinic with complaints of dysuria and bleeding at the glans of penis on May 2, 1985. At the first presentation the tumor mass with necrotic and hemorrhagic character was localized around the urethral orifice and the entire glans of penis had a hard consistency. Moreover, numerous soft cutaneous nodules ranging from a small bean to a hen's egg in size spread over the total body surface. The nodules varied in property from even in height on the skin surface, half-spherical, and pedunculated. His family history was not contributory as far as neurofibromatosis was concerned. On May 15, the glans of penis was amputated and histological diagnosis was malignant melanoma with marked vascular and neural permeation. Review of the literature showed that our patient is the third case of malignant melanoma associated with neurofibromatosis in Japan.
