title: [Diffuse alveolar damage after inhalation of zinc oxide fumes].
abstract: A 57-year-old man with a 37-year occupational history of welding was admitted for high fever and dyspnea after inhalation of zinc oxide fumes during a period of welding without a protective mask. Chest radiography and CT showed bilateral diffuse ground-glass opacities, and blood gas analysis revealed that PaO2 was 48.1 torr in room air. A transbronchial lung biopsy was done, and revealed diffuse alveolar damage. We diagnosed the case as chemical pneumonia due to the inhalation of zinc oxide, and prescribed prednisolone 40 mg per day. As a result, his symptoms improved within several days. The inhalation of zinc oxide fume usually causes metal fume fever, but chemical pneumonia is also reported on rare occasions. As far as our examination of the literature has disclosed, this is the first report of diffuse alveolar damage after inhalation of zinc oxide fume.
