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
