Abstract
The eosinophilic lung diseases are a group of pulmonary disorders characterized by
an increase in blood and/or lung eosinophils. These disorders can be primary pulmonary
disorders or the secondary manifestation of other systemic or pulmonary conditions,
infection, drug reaction, or malignancy. The approach to a patient with eosinophilic
lung disease involves a thorough history and physical examination, review of exposures
and appropriate testing, often including bronchoscopy or lung biopsy, to establish
a specific etiology and determine therapy. Eosinophilic lung disease can be suspected
based on either the finding of pulmonary disease with blood eosinophilia, pulmonary
disease with bronchoalveolar lavage eosinophilia, or pulmonary disease with lung tissue
eosinophilia on lung biopsy.
