LAUSR

Silvery hair syndrome is a rare, autosomal‐recessive entity characterized by silvery gray hair, eyebrows, and eyelashes and may be associated or not with immunologic or neurologic alterations. Two main types have been recognized: Chediak‐Higashi syndrome and Griscelli syndrome. Hair shaft examination under light microscopy has been a useful tool to differentiate Chediak‐Higashi syndrome from Griscelli syndrome, although distribution of melanin varies according to hair color related to ethnicity. The objective was to compare the pattern of melanin in the skin and with the pattern of melanin distribution in the hair shaft.
