Griscelli syndrome: a case report of Reye's syndrome and atopic dermatitis history.

Griscelli syndrome (GS) is a rare autosomal recessive disorder that results in pigmentary dilution of the skin and the hair (silver hair), with the presence of large clumps of pigment in hair shafts, and an accumulation of melanosomes in melanocytes. Sixty cases of GS have been reported in the literature, but we could find no description of its oro-dental symptoms. Reye's syndrome (RS) is characterized by acute noninflammatory encephalopathy and renal and hepatic failure, while atopic dermatitis (AD) is a skin disorder with an immunologic basis. The aim of this paper is to describe the oro-dental and physical findings in a girl who had been diagnosed with GS at 3.5 years of age; she also had AD as well as a history of RS at infancy. We discuss the possible relationship between the three syndromes.
