Dermal melanocytosis of the helix.
A 2-year-old Japanese boy had a congenital gray-blue macule involving the right helix along with a few melanotic spots on both sclerae. Histopathology showed dermal melanocytosis. Q-switched alexandrite laser treatment induced a good cosmetic response. This patient shows the overlap between Ota and Ito nevi, and we suggest dermal melanocytosis is better used as a generic term for these unusual pigmentations.
