Deep Penetrating Nevus
HistopathologyThe deep penetrating nevus (DPN) is mostly intradermal nevus, and a few are compound nevus. Under low magnification, the DPN shows a wedge-shaped growth pattern: The broad base parallel to the epidermis and the apex penetrate into the deep reticular dermis and fat (Fig. 1). At higher magnification, tumor cells are identified as melanocytes that mainly locate in the dermis, generally without involvement of the dermal papilla not affected (Fig. 2A).
