We herein report a case of hard metal lung disease that was successfully treated with inhaled corticosteroids. A 46-year-old man was admitted to our hospital due to coughing and an abnormal shadow on a chest radiograph. He had worked as a hard metal tool sharpener for five years. Chest computed tomography scans showed centrilobular micronodules and areas of ground-glass opacity in the bilateral lung fields. Video-associated lung biopsy specimens revealed bronchocentric interstitial pneumonia and cellular bronchiolitis. A high-energy dispersion X-ray microanalysis detected tungsten. The patient was diagnosed with hard metal lung disease. Inhaled corticosteroid therapy (800 μg of ciclesonide hydrofluoroalkane daily) resolved the patient's symptoms, elevated KL-6 level, abnormal areas of chest opacity and obstructive, restrictive and diffusion impairments.
