[Bronchial asthma, eosinophilia and lung infiltrates (Churg-Strauss syndrome)].

In a patient suffering from bronchial asthma of several years' standing, recently worsening physical condition, marked eosinophilia and pulmonary infiltrates, the clinical diagnosis of Churg-Strauss syndrome (CSS) was confirmed histologically. The patient improved impressively after the initiation of immunosuppressive therapy, in contrast to the often lethal course of this disease. Therefore, the possibility of CSS should be considered in every case of bronchial asthma with progressive worsening of the physical condition or in presence of leukocytosis with significant eosinophilia.
