[A case of pulmonary hemosiderosis associated with rhumatoid arthritis with LE cells (author's transl)].

In a three and a half old girl, we have noticed the apparition: first, of on idiopathic pulmonary hemosiderosis; then, five months later, of a rheumatoid arthritis with LE cells and antinuclear antibodies of very difficult detection. The meaning of this articular involvement is discussed: rheumatoid arthritis with LE cells, or rheumatoid arthritis marking the beginning of a systemic lupud erythematosus. The literature concerning the association of an hemosiderosis and a connectivite is reviewed.
