title: Pigeon fanciers lung: a case report.
abstract: BACKGROUND
  Pigeon fanciers lung, a form of hypersensitivity pneumonitis, is an unusual but important occupational and recreational cause of severe and debilitating breathlessness.
  
  
  METHODS
  We report the case of a 61-year-old Caucasian man suffering with severe breathlessness due to pigeon fanciers lung. He had previously raced and bred pigeons for 25 years but had discontinued the pursuit a decade ago.
  
  
  CONCLUSIONS
  Pigeon fanciers lung can be associated with severe debilitating dyspnoea and patients may present many years after exposure to avian antigens. Physicians should be encouraged to take a detailed occupational and recreational history in any patient presenting with unexplained breathlessness.
