The nomenclature and histologic criteria for atypical nevi remains controversial though there is general agreement on the following features:

Architectural disorder with asymmetry Intraepidermal melanocytes extend beyond the main dermal component Subepidermal fibroplasia Lentiginous melanocytic hyperplasia with spindled or epithelioid melanocytes Nevus cell nests are of variable size and bridge adjacent rete ridges Variable degrees of melanocyte atypia.
