title: Eosinophilic granuloma of the temporal bone.
abstract: Otological involvement in Histiocytosis X, although infrequent, may be present in any of the forms of this entity. The otologist must keep Histiocytosis X in mind in the differential diagnosis of cases presenting with post-aural swelling, non purulent otorrhea and absence of fever and pain in children under three-years old. Some aspects of clinical presentation and treatment are discussed.
