Löffler's syndrome secondary to crack cocaine.

Eosinophilic pulmonary infiltration is an uncommon presentation from cocaine abuse. We present a patient with migratory pulmonary infiltrates and eosinophilia consistent with Löffler's syndrome. Our review uncovered two other similar patients. The importance of early recognition is stressed in our report. Either abstinence from cocaine usage and/or steroids result in resolution of this illness.
