Giant cell interstitial pneumonia in two hard metal workers: the role of bronchoalveolar lavage in diagnosis.
Two cases of hard metal lung disease and pathological findings of giant cell interstitial pneumonia are reported. The cases worked in different factories manufacturing hard metal parts from tungsten carbide and cobalt. Pathological specimens were obtained by percutaneous thoracoscopy and transbronchial lung biopsy. X-ray microanalysis detected only tungsten carbide in the lung specimen of one case. Bronchoalveolar lavage showed diagnostic bizarre macrophages in the lavage fluid.
