A dual concept of nevogenesis: theoretical considerations based on dermoscopic features of melanocytic nevi

Abstract

The dermoscopic features of melanocytic nevi in children are clearly different from those in adults. While nevi in children show almost exclusively globular patterns, those in adults usually exhibit reticular patterns. These remarkable differences could be explained by a dual concept of nevogenesis, based on current clinico-epidemiologic, dermoscopic, histopathologic and genetic data.
