title: Cigarettes-induced acute eosinophilic pneumonia: a case report.
abstract: BACKGROUND
  Idiopathic acute eosinophilic pneumonia is a rare disease. It presents with acute febrile illness, respiratory insufficiency, pulmonary infiltration and high eosinophil levels in Bronchoalveolar lavage fluid. Pathogenesis is not well understood, but may relate to the exposure to exogenous substances.
  
  
  METHODS
  We present a case of 20-year-old man, who developed idiopathic acute eosinophilic pneumonia after smoking cigarettes and required intubation with mechanical ventilation. His symptoms resolved quickly after corticosteroids therapy.
  
  
  CONCLUSIONS
  Acute eosinophilic pneumonia should be considered in the differential diagnosis of a patient with acute febrile respiratory illness, diffuse bilateral pulmonary infiltrates and recent modification in smoking habit.
