title: Nocardiosis after corticosteroid therapy for malignant thymoma.
abstract: BACKGROUND
  Nocardia asteroides is an opportunistic infection caused by an aerobic actinomycete, which, in the immunocompromised host, can be associated with severe invasive disease with a predilection for the brain.
  
  
  RESULTS
  The authors describe a 62-year-old man with a malignant thymoma that was clinically responsive to oral prednisone. N. asteroides sepsis subsequently developed, leading to his death.
  
  
  CONCLUSIONS
  Nocardiosis should be considered a potential pathogen in this immunocompromised setting.
