[A hemophagocytic syndrome revealing a Griscelli syndrome type 2].

Abstract

Griscelli syndrome type 2 is a rare autosomal recessive disorder, due to a mutation in RAB27A gene. It associates partial albinism, silver hair and immune deficiency. We report the case of a 6 year-old boy who was admitted to the Emergency department with severe sepsis complicated by hemophagocytic syndrome. Many clinical and biological criteria leads to the diagnosis of type 2 Griscelli syndrome: consanguineous family, recurrent infection, absence of psychomotor retardation, oculocutaneous albinism, silver hair, occurrence of hemophagocytic syndrome and especially the pathognomonic appearance on microscopic examination of the hair. The absence of giant organelles inclusion in all granulated cells eliminated Chediak-Higashi syndrome.
