Abstract

Background. Fluoropolymers have been widely used in various products, and inhalation of pyrolyzed fumes could cause lung injury. Case. A 55-year-old woman fell asleep with a pan on the stove. After two hours, she was admitted to our hospital with complaints of difficulty in breathing. She was found to have fever and hypoxia, and chest computed tomography scans showed diffuse ground-glass opacities in bilateral lungs. The number of neutrophils in bronchoalveolar lavage fluid was increased and transbronchial lung biopsy specimen showed mild pulmonary alveolitis. We made a diagnosis of lung injury due to inhalation of polymer fumes from a history of fluoropolymer coated pan use. The symptoms and diagnostic imaging findings rapidly diminished. She was discharged six days after admission. Conclusions. There is a possibility of polymer fume fever resulting from daily life activities.
