[Drug-induced pulmonary lesions].

The problem of the drug induced pulmonary toxicity (cytotoxic and non-cytotoxic drugs) is discussed. This domain of modern pathology is in continuous development, although yet insufficiently delineated. The essential pathogenic mechanisms are presented as well as the main histopathological lesions (i.e., interstitial pneumonia and pulmonary fibrosis). The usual lesional aspects specific to certain drugs are also reviewed. For the principal chemical substances in this category, the clinical and radiological aspects are given, also the various treatment indicated, the evolution and the prognosis of the drugs induced pulmonary disease.
