Melanocytic dysplasia and multiple melanoma of the vulva

We report a case of a 24-year-old woman with multiple pigmented lesions on her vulva. Histologically the lesions showed a heterogeneous pattern: the majority consisted of melanoma in situ and invasive melanoma; in a few lesions a much less clear-cut picture was found with only melanocytic dysplasia of various degrees. Our case shows the relationship between anomalous melanocytic proliferation of the vulva and vulvar melanoma and underlines the necessity of a thorough check of all melanocytic vulvar lesions also in young patients.
