title: Procarbazine-induced interstitial pneumonitis with a normal chest x-ray: a case report.
abstract: Pulmonary toxicity due to cytotoxic drugs is well described in the literature. This is most commonly described in association with bleomycin, busulfan, and methotrexate. This report presents a case of interstitial pneumonitis with a normal chest x-ray that is most certainly due to procarbazine. In addition, the role of gallium-67 citrate scintigraphy in early diagnosis is discussed. This is especially important since discontinuation of the drug before radiographic manifestations of pulmonary toxicity become evident may prevent permanent pulmonary injury and its sequelae.
