Acute eosinophilic pneumonia following artenimol-piperaquine exposure

Abstract

Acute eosinophilic pneumonia (AEP) has been reported following chloroquine or mefloquine exposure, both structurally related to piperaquine. We report a case of AEP with typical CT scan patterns, hypereosinophilia in blood (9.8 109/l), and bronchoalveolar lavage (78% of 600 000 cells/ml), 10 days after artenimol-piperaquine exposure in a 26-year-old man.
