A case of histiocytosis X with spontaneous remission is described. The patient presented is an infant of six months, with cutaneous and bony lesions. No specific treatment was given, but the child was free of signs and symptoms two years later. The histological findings of eosinophils and fibrosis are probably of good prognostic import.
