title: [Pneumomediastinum complicating the anti-synthetase syndrome].
abstract: BACKGROUND
  Pneumomediastinum is a rare but classical complication of dermatomyositis. Its development is a serious matter and necessitates prompt recourse to aggressive treatment with corticosteroids combined with immuno-suppressants or intravenous human immunoglobulin.
  
  
  METHODS
  We report the case of a 63 year old woman presenting with pulmonary infiltration, in the presence of dermatomyositis, as a clinical manifestation of the anti-synthetase syndrome. The progress was rapidly unfavourable with pneumomediastinum and acute respiratory distress despite initial treatment with corticosteroids followed by human immunoglobulin and immunosuppressants.
  
  
  CONCLUSIONS
  The identification of cutaneous or muscular signs in the initial investigation of a pulmonary infiltrate should lead to a search for anti-synthetase antibodies in order to determine the optimal clinical management as quickly as possible.
