Dermoscopy of an acral congenital melanocytic nevus

Congenital melanocytic nevi carry a risk for malignant transformation into melanoma, therefore early detection of suspicious features is crucial to reduce mortality rates. Dermoscopy improves the early detection of melanoma while reducing the number of unnecessary excisions of benign pigmented skin lesions. Dermoscopically, congenital melanocytic nevi are often characterized by the presence of a cobblestone pattern, but to date, little is known about the dermoscopic features of acral congenital melanocytic nevi. We report an acral congenital melanocytic nevus typified by the presence of three different dermoscopic patterns that are commonly seen in acquired melanocytic nevi of palms and soles.
