Griscelli et al described this syndrome in 1978. Since then, only in approximately 60 cases have been reported, most from the Turkish, and Mediterranean population. In microscopic examination, si...

Polarized light microscopy of hair shafts aids in the differential diagnosis of Chédiak-Higashi and Griscelli-Prunieras syndromes.

PURPOSE To study and compare the appearance of hairs from patients with Chédiak-Higashi and Griscelli-Prunieras syndromes under light and polarized light microscopy. METHOD Hairs from 2 Chédiak-Higashi and 2 Griscelli-Prunieras patients were obtained and examined under normal and polarized light microscopy. RESULTS Under light microscopy, hairs from Chédiak-Higashi patients presented evenly...

Paediatric Dermatology Column: Case Report Silvery hair syndromes: report of familial cases of Griscelli syndrome in three siblings

Silvery hair is a rare clinical feature, common in a group of rare syndromes, which usually present in the paediatric age group termed together as "silvery hair syndromes". We report a consanguineous family in which three out of four siblings had silvery hair and neurological deficits and were diagnosed to have Griscelli syndrome.

Griscelli syndrome type 2: a novel mutation in RAB27A gene with different clinical features in 2 siblings: a diagnostic conundrum

Griscelli syndrome type 2 (GS2) is a rare autosomal recessive disease caused by mutations in the RAB27A gene. It is characterized by cutaneous hypopigmentation, immunodeficiency, and hemophagocytic lymphohistiocytosis. We describe 2 brothers who had GS2 with clinically diverse manifestations. The elder brother presented with a purely neurological picture, whereas the younger one presented with ...
