Different types of melanocytic nevi do exist in relation to their epidemiology, evolution, morphology, genetics, and their associated melanoma risk. The introduction of dermoscopy has opened a new morphologic dimension of melanocytic nevi; this along with recent progresses in our understanding of the molecular pathways involved in the formation of nevi opened new ways to classify nevi.
