[Diffuse alveolar hemorrhage as the only manifestation of antiphospholipid syndrome]. / Rozlane krwawienie pecherzykowe jako jedyna manifestacja zespolu antyfosfolipidowego.

The antiphospholipid syndrome is characterized by the presence of antiphospholipid antibodies and the association of protean clinical manifestations as a result of both venous and arterial thrombosis. While pulmonary embolism (secondary to deep vein thrombosis) is common and well-known disturbance in antiphospholipid syndrome, recently there are growing number of case reports describing nonthrombotic lung pathologies in APS. We present here a young male with antiphospholipid syndrome, whose the only manifestation was diffuse alveolar hemorrhage.
