title: [Pulmonary abscess and Pyoderma gangrenosum].
abstract: BACKGROUND
  Pyoderma gangrenosum is the ulcerative form of neutrophilic dermatoses. The most frequent extracutaneous localizations are the lungs, joints, and digestive tract.
  
  
  METHODS
  We report a case of Pyoderma gangrenosum, which presented first as an aseptic lung abscess. The first cutaneous lesions occurred 9 months later, with skin ulcerations on the thorax and on surgical scars. The histological diagnosis was made on skin biopsies. There was no associated abnormality except for IgA monoclonal gammapathy. Clinical improvement was noted with immunosuppressive treatment.
  
  
  CONCLUSIONS
  This infrequent case report underlines that lung abscesses may be of non-infectious origin, that in Pyoderma gangrenosum, skin lesions may be come several months after extracutaneous manifestations, among which lungs abcesses are the most frequent.
