[Idiopathic pulmonary hemosiderosis (2 clinical cases)].

The authors present two children with idiopathic pulmonary hemosiderosis, in whom the diagnosis was very difficult on the basis of evolution by stages, hypochromic anemia, hemoptoic sputum containing siderophages, cloudy pulmonary shadow and microscopical skin and lung examination that evidenced marked alterations of the elastic system and siderophages on pulmonary tissue preparations. All the clinical, hematologic and radiological signs were considerably improved by corticoid therapy. The necessity is stressed of such investigations in children with anemia.
