A case of pulmonary toxicity after chlorozotocin (DCNU) is described. This patient developed shortness of breath, nonproductive cough, and interstitial infiltrates after his third dose of DCNU. This was documented on pulmonary function tests which showed a reduction in vital capacity and pulmonary diffusion capacity. Similar findings have been reported in restrictive pulmonary disease associated with other nitrosoureas. This is the first case reported of pulmonary toxicity induced by DCNU.
