Dermoscopic patterns of acral melanocytic lesions in skin of color

Abstract

Acral lentiginous melanoma (ALM) is a rare but aggressive subtype of melanoma often associated with poor prognosis. Although overall incidence is rare, ALM accounts for a larger proportion of melanomas among black, Asian, and Hispanic individuals than among white individuals. Similarly, the proportion of acral melanocytic nevi tends to be greater in ethnic skin despite a lower overall nevi count. Dermoscopy can help differentiate between benign and malignant acral melanocytic lesions. Herein, we discuss the population trends of acral melanocytic lesions in patients with skin of color. We also examine the diagnostic challenges of acral lesions and review the dermoscopic patterns unique to acral volar skin.
