Malignant melanoma of the vulva.

Malignant melanoma of the vulva is reviewed and four cases are presented. Fewer than 400 cases have been reported, from 0.05 to 0.5% of female genital cancers. Radical vulvectomy with inguinal lymph node dissection is of uncertain value and the prognosis usually is poor. Wide local excision alone is suggested for level II melanomas, and in such instances the prognosis may be favorable.
