[Parasitic eosinophilic lungs]

The eosinophilic lung is a term used to identify a heterogeneous group of parasitic diseases leading to common manifestations including alveolar or tissular pulmonary eosinophilia and, classically, radiological visible lesions of the lung. The different clinical presentations--Löffler's syndrome, larva migrans syndrome and tropical pulmonary eosinophilia are analyzed in this article and the particular features of the different causal parasites are discussed. Positive and differential diagnostic procedures in patients with pulmonary eosinophilia due to mycoses, drugs, vasculitis or an unknown cause are detailed.
