ABSTRACT
Melanonychia refers to a black-brown-grey pigmentation of the nail plate. It is caused by the presence of melanin and commonly appears as a longitudinal band (longitudinal melanonychia). Differential diagnosis encompasses benign and malignant conditions. Nail dermatoscopy (onychoscopy) is a reliable diagnostic tool that provides useful information about nail pigmentations. In this article, the causes, clinical and dermatoscopic features of melanonychia have been reviewed through an algorithm.
Keywords: Melanonychia; dermatoscopy; onychoscopy; nail diseases; melanoma
