Faisalabad histiocytosis mimics Rosai-Dorfman disease: brothers with lymphadenopathy, intrauterine fractures, short stature, and sensorineural deafness.

| Abstract |
Rosai-Dorfman disease (RDD) is a rare, sporadic histiocytic disorder characterized by painless but protracted lymphadenopathy. Its etiology remains unclear. The observation of congenital disease and reports of familial cases with seven pairs of siblings including three sets of identical twins suggests a genetic predisposition in some patients with this condition. We now report two brothers of consanguineous Palestinian parents, whose lymphadenopathy, lymph node histology, and polyclonal hypergammaglobulinemia indicated RDD. The presence of intrauterine fractures, short stature, and sensorineural hearing impairment suggested a rare familial form of the disorder. Moynihan et al. recently described a Pakistani family with a familial histiocytic disorder highly reminiscent of the brothers reported here, whose lymph node morphology was apparently consistent with RDD as well. The presence of sensorineural deafness, short stature, and joint contractures, however, suggested a separate, rare autosomal recessive syndrome referred to as Faisalabad histiocytosis, after the family's place of origin. We believe that the brothers described here represent a second family with Faisalabad histiocytosis, which mimics RDD histologically.
