Chronic eosinophilic pneumonia is a rare condition of unknown origin. It was not until 1969 when Carrington et al defined it as a disease separate from the group of diseases associated with lung disease and eosinophilia. We describe a case of a young woman who presented with a chronic cough followed by a fever. Additional tests showed peripheral eosinophilia in bronchoalveolar lavage with 60%eosinophils. Chest x-rays showed bilateral infiltration in the upper lobes. Corticosteroid therapy improved the picture, the patient still remains asymptomatic.
