[Lethal paraquat poisoning caused by spraying in a vinyl greenhouse of causing pulmonary fibrosis with a hepatorenal dysfunction].

A 46-year-old man was hospitalized because of general fatigue. He died of respiratory failure caused by hepatorenal dysfunction. Histologic findings in the lungs were consistent with paraquat poisoning. However, he did not have a history of drinking paraquat, but did have an occupational history of spraying paraquat in a vinyl greenhouse. Retrospectively, chest X-ray films and CT scans showed findings typical of paraquat poisoning. We should inform farmers that paraquat can be toxic when used in vinyl greenhouses.
