Silvery grey hair: clue to diagnose immunodeficiency.

Silvery hair is a common presentation of rare group of autosomal recessive disorders called Silvery hair syndromes including Griscelli syndrome (GS), Chediak-Higashi syndrome, and Elejalde syndrome. GS is characterized by a silvery grey sheen to hair, large clumped melanosomes in hair shaft, partial albinism, and variable cellular immunodeficiency. We report two cases of GS with classical clinical features and confirmatory findings by microscopic skin and hair examination.
