Diffuse alveolar hemorrhage in limited cutaneous systemic sclerosis with positive perinuclear antineutrophil cytoplasmic antibodies.

Abstract

A 54-year-old woman with limited cutaneous systemic sclerosis (SSc) developed repeated diffuse alveolar hemorrhage with positive perinuclear antineutrophil cytoplasmic antibodies (pANCA). Reports of diffuse alveolar hemorrhage in SSc have been rarely described only in the diffuse clinical variant. To our knowledge, this is the first report of pANCA positive diffuse alveolar hemorrhage in the limited form of SSc. Diffuse alveolar hemorrhage is a rare, but potentially life threatening cause of respiratory distress in the limited form of SSc that should be recognized and treated effectively.
