Melanocytic lesions of the genital area, especially those on the vulva, may present great difficulty in histological interpretation. A histological diagnosis of malignant melanoma was made in more than one third of 56 genital area melanocytic lesions submitted in consultation to the authors. The median age of the patients with these lesions was 25 years. This article is a clinicopathological study of these lesions and distinguishes them from malignant melanoma. The stroma of the lesions of the genital area was different from the stroma seen in the dysplastic nevi and melanoma. The differences in the stromal form in the diverse lesions is useful in diagnosis and is of profound biological significance. The stroma in the reported lesions and in some lesions of melanocyte neoplasia is described in detail, and its biological significance is discussed. Three sets of cases are used in this comparative study to delineate the clinicopathological nature and the biology of the genital nevi. The 56 cases submitted in consultation constitute the primary series of our work (The Clark Cutaneous Pathology Laboratory Series). These are compared with a series of cases from the Pigmented Lesion Group of the University of Pennsylvania and Pathology Services, Inc, and another series of cases from the Genetic Epidemiology Branch of the National Cancer Institute. |
