title: A chronic eosinophilic pneumonia case with long exposure to isocyanates.
abstract: Chronic eosinophilic pneumonia (CEP) is a disease with unknown etiology, characterized by peripheral blood eosinophilia and abnormal eosinophil accumulation in the lungs. A 43-year-old male with 30 years history of exposure to isocyanates was admitted with the complaint of sputum, cough, progressive dyspnoea, and weight loss. Physical examination revealed bilaterally decreased breath sounds and extensive rales. On laboratory analysis; leukocytosis (12.3 10(3)/proportional variant L), hypereosinophilia (30%), elevated CRP and RF (1000 IU/ml), and IgE levels (1160 IU/ml) in the serum were observed. Chest radiograph and computed tomography on admission showed reticulonodular pattern at both lung fields. Pulmonary function tests assumed a restrictive pattern and a low diffusing capacity. Bronchoalveolar lavage revealed a marked eosinophilia (50%). Transbronchial lung biopsy indicated eosinophilic pneumonia. In this case we aimed to describe a rare case of CEP probably caused by exposure to isocyanate.
