Eosinophilic lung diseases are a group of heterogeneous disorders characterized by blood eosinophilia and pulmonary infiltrates. These conditions are very rare in Pediatric sunset.
A 12-year-old nonsmoking asthmatic girl was admitted for general malaise and dry fatiguing cough. Diagnostic course reveled marked hypereosinophilia and chest radiography indicated multifocal and circumscribed bilateral pulmonary areas of consolidation. Bronchoscopy excluded the presence of neoplastic cells but marked hypereosinophilia was found in bronchoalveolar lavage. The increased number of eosinophils in blood and in bronchoalveolar lavage, the radiological findings were suggestive of Chronic idiopathic eosinophilic pneumonia.
Chronic idiopathic eosinophilic pneumonia is a rare disease, especially in Pediatrics. Often misdiagnosed, the treatment is based on corticosteroid administration, but there is no consensus on the right management of the disease.
