Abstract:
The dysplastic nevus is a rare form of melanocytic nevus in Korean people. During the past 5 years the authors experienced 5 cases in the St. Mary's Hospital and Kang Nam St. Mary's Hospital. The criteria and the histologic findings of dysplastic nevi are debated in the western literature. Clinically, all cases were greater than 5 mm in size with ill defined irregular borders and irregularly distributed pigmentation. Histopathologically, all cases showed numerous discrete individual nests of melanocytes located in the dermoepidermal junction and the papillary dermis and were characterized by extension of dermoepidermal component of the nevus at the "shoulder" beyond the dermal component of the nevus. There was no cytologic atypia of nevus cells in all cases. Our cases lacked personal or family history of malignant melanoma. Therefore, we believe our cases are nonfamilial, sporadic and benign nevi with no prognostic significance. A brief review of the literature and a discussion on the term "dysplastic" and clinicopathologic correlation are made.
