Incidence of melanoma and outcomes of longitudinal melanonychia in a cohort of cases referred to a London dermatology department

Abstract

Longitudinal melanonychia is a pigmented longitudinal band on the nail plate and may occur due to melanocyte activation, nail matrix nevus, lentigo or subungual melanoma.¹ In a racially diverse community, melanonychia is a relatively common presenting complaint. However, despite this, little is known about the incidence of melanoma in longitudinal melanonychia, as well as variations in management approaches.
