- Abstract
A 43-year-old man with a dyspnea, and cough had been a welder for 20 years, and had raised pigeons for 30 years. A pre-diagnosis of hypersensitivity pneumonitis was proposed with multiple micronodular opacities in radiology, exposure to pigeons, and hypoxemia. However, it was ruled out with continuing lung symptoms though avoidance of pigeons, no alveolitis in the bronchial lavage, corticosteroid insensitivity, and normal diffusion lung capacity. A diagnosis of welder's lung disease was made with the occupational environment consisting of iron dust particles, compatible chest radiology, and positive staining for ferritin (Prussian blue stain) of the macrophages in the bronchial lavage. His hypoxemia was thought to improve after bronchial washing. He was recommended to quit his job and quit smoking, as well as feeding pigeons, since these factors potentially had an effect and predispose lung fibrosis, asthma, and cancer.
