[Penicillamine-induced bronchiolitis obliterans diagnosed by transbronchial lung biopsy].
A 57-year-old woman had been treated with penicillamine (200 mg/day) for degenerative arthritis initially misdiagnosed as rheumatoid arthritis since 2003. She presented with dyspnea and was admitted to our hospital in 2004. Pulmonary function tests revealed mixed pattern of dysfunction with severe airway obstruction. Chest computed tomography showed mosaic ground-glass opacities. Bronchoalveolar lavage fluid (BALF) demonstrated increase in total cells and lymphocytes. Since specimens of transbronchial lung biopsy (TBLB) showed lymphocytic infiltration in membranous bronchiole and occlusion of the membranous bronchiole lumen, bronchiolitis obliterans was diagnosed by TBLB. After penicillamine, which had been administered for 7 months, was stopped, she was successfully treated with steroid and macrolides.
