DEEP PENETRATING NEVUS

By Gary M. White, MD


The deep penetrating nevus (DPN) is characterized histologically by a wedge-shaped distribution of melanocytes that penetrate deep into the dermis.

Clinical

The deep penetrating nevus usually presents as a solitary, deeply pigmented lesion, 1.0 cm or less in size occurring in the first 4 decades of life.  Less than 5% are reported to develop after the age of 50 years. It may be bluish, resembling a blue nevus.   Preferred sites are the face, trunk or proximal extremities. There is one report of linear, multiple DPN on the scalp behind the ear [AD 2003;139;1608].

Treatment

Simple excision is appropriate.
