[Drug-induced lung diseases].

Drug-induced interstitial pneumonias are systematically considered in the differential diagnosis of the interstitial pneumonias. The presentation may be acute, sub-acute or chronic, with the same drug possibly leading to either acute or subacute/chronic interstitial lung disease (e.g. amiodarone). There is no definite diagnostic criterion, the final diagnosis relying on the clinical and imaging features, the chronology of pulmonary manifestations, and the prevalence of reported cases with the suspected drug.
