Nevi Features

• 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 collagen between adjacent structures

• Nests can appear as though they are stretched horizontally opposed to the more ovoid basal cell aggregations
