Dermoscopic features of common nevi: a review

Abstract

The differentiation between benign and worrisome melanocytic lesions may be challenging in the absence of the glaringly obvious clinical features that define a cutaneous malignancy. In such situations, dermoscopy may prove useful in further defining characteristics that are more indicative of a benign lesion, which can ultimately help avoid an unnecessary biopsy. Recognizing of the dermoscopic findings of benign nevi, taking into consideration the predominant pigment pattern and its organization, may aid in the evaluation of pigmented lesions. Benign nevi tend to exhibit symmetry, regularity in shape, and uniformity of dermoscopic structures. This article reviews the clinical and dermoscopic features of common acquired nevi (dermal, compound, and junctional), blue nevi, and congenital nevi.
