Nails: Diagnostic clules to genodermatoses.

Abstract

Nails are cutaneous appendages mostly involved in mechanical functions. However, nails may reflect presence of various systemic disorders evidenced by alteration of their shape, size, color or texture. Genodermatoses are multisystem disorders with cutaneous involvement. Many of the genodermatoses present with nail changes and some of these may be the clinical pointers to the diagnosis. Diagnostic clues to various genodermatoses derived from nail findings have been discussed.
