Histiocytosis X, a proliferation of histiocytes of indefinite etiology, is classified into localized (eosinophilic granuloma) and diffuse, acute (Letterer-Siwe) or chronic (Hand-Schüller-Christian) varieties. The cause of such a proliferation remains unknown.1 Inflammatory, allergic, or neoplastic origins are suggested, but as yet remain unproved.2,3These three forms, although clinically different, overlap each other, and various combinations or "transitional" forms producing bizarre manifestations have been described.This report deals with a fulminant disseminated histiocytosis with predominant pulmonary pathology, which appeared in a young woman. Such a combination is exceptional. To our knowledge only one similar case has been reported in the literature.4
