Repeating saw tooth pattern of rete pegs characteristic of junctional melanocytic nevi, representing rete elongations Alternating hyporeflective and hyperreflective vertical extensions from the base of the epidermis Intradermal nevi typically lack the junctional saw tooth appearance but possess hyporeflective nest clusters in the dermis Unlike morpheaform nests these clusters do not possess hyperreflective compressed […]
