Overview
Faisalabad histiocytosis is a familial histiocytic disorder . It is a type of histiocytosis - lymphadenopathy plus syndrome.
Historical Perspective
Moynihan et al. described Faisalabad histiocytosis in a Pakistani family. It was named after the family's place of origin.
Pathophysiology
Faisalabad histiocytosis has an autosomal recessive pattern of inheritance.
Genetics
Homozygosity for splice site mutations in the gene SLC29A3 were identified in the patients.
Differentiating from other diseases
The histological features of Faisalabad histiocytosis resemble those of Rosai-Dorfman disease (RDD). RDD can be differentiated from Faisalabad histiocytosis by the presence of massive painless cervical lymphadenopathy, fever, elevated erythrocyte sedimentation rate and presence of polyclonal hypergammaglobulinemia.[1]
