Unna nevus of the scalp: Unusual clinical presentation

Abstract

The term "dermal melanocytic nevi" includes a group of clinically and histopathologically distinct subtypes, including Miescher’s nevus, flat nevus, and Unna’s nevus. Flat nevi are the most common clinical type. Miescher’s and Unna’s nevi have different clinical and histopathological features, making them easily distinguishable. We present a case of an Unna’s nevus in the posterior of the scalp with unusual localization.
