Pulmonary damage due to paraquat poisoning through skin absorption.

A case of recovery from acute respiratory insufficiency due to paraquat is described. A 57-year-old farmer developed breathlessness, high fever and interstitial infiltrates in the upper and middle lung fields few days after percutaneous paraquat poisoning with rapid evolution to pulmonary fibrosis. Anti-inflammatory drugs and antioxidants, were administered to the patient, though with a delay, with some improvement; the patient survived despite residual lung fibrosis. Paraquat lung, as confirmed by this paper, is not invariably fatal.
