Melanonychia is characterised by brown to black discolouration of a finger or toenail. Longitudinal melanonychia describes a pigmented band and is due to melanin within the nail plate. Longitudinal melanonychia is most often benign and arises from a pigmented melanocytic naevus (a mole) or a lentigo (a freckle).
What vitamin deficiency causes vertical lines in fingernails?
