title: Pigmentary abnormalities of the nails with emphasis on systemic diseases.
abstract: The nails can change colors for many reasons. White bands called leukonychia are especially common. The shape of the white band, that is, concave or convex, indicates the site of injury. Color changes in the nails may also be a sign of a variety of cutaneous or systemic disorders.
