[Clinical analysis of 16 cases of malignant head and neck melanoma]

Subjects were 16 patients--5 men and 11 women aged 46-82 years (mean: 61 years)--with malignant melanoma of the head and neck treated at our clinic from 1972 to 1988. Histologically, 1 subjects was amelanotic and 15 melanotic type. Primary lesions were 10 involving the nasal cavity, 2 the paranasal sinus, 2 the gingiva, 1 the lip, and 1 primary unknown. They were treated with or without multimodal surgery, radiation, chemotherapy, and immunotherapy. Of 12 treated using local surgery, local recurrence was seen in 6 in 7 areas. Two-year survival was 44% and 5-year survival 22%. The prognosis of malignant head and neck melanoma is poor but has gradually improved due to preoperative decisions on disease spread and the introduction of multimodal therapy.
