We report two cases of perindopril-associated pneumonitis with typical
drug-induced clinical features, In the first case, biopsies showed gr
anulomatous sarcoid-like lesions; in the second, bronchial wall eosino
phil infiltration was reported with increased blood eosinophil count.
In these two cases, improvement was obtained by withdrawal of the drug
and was completed with steroids. All other causes were ruled out. Ang
iotensin-converting enzyme inhibitor (ACEI)-induced pneumonitis is sti
ll rare but has to be recognized as a real side-effect.
