Melanocytic Nevi – Melanoacanthoma

August 14th, 2011

Melanoacanthoma is a benign melanocytic nevus that I occasionally encounter in both my The Woodlands dermatology and Conroe dermatology offices.  The appearance of a Melanoacanthoma is very similar to a pigmented seborrheic keratosis, which is a black scaly plaque that seems to be “stuck on” the skin.  Histologically, Melanoacanthomas have features of both a seborrheic keratosis and a nevus, thus the overlap in its clinical features.  As Melanoacanthomas are benign, no treatment is necessary unless cosmetically desired and this can best be accomplished through shave removal.
