[Recurrent hemoptysis in a 29-year old woman].

A 29-year old woman was admitted with recurrent hemoptysis. Due to the combination of hemoptysis, alveolar infiltrates and anemia a diffuse alveolar hemorrhage syndrome was suspected. After exclusion of underlying diseases and due to the typical histology we confirmed the diagnosis of an idiopathic pulmonary hemosiderosis. In consequence of an acute progression of the disease with pulmonary hemorrhage and severe anemia an empiric therapy with corticosteroids and azathioprine was initiated, resulting in a distinct recovery.
