This article reports 41 cases of suspected pneumoconiosis needle (Tr-ucut ~ R needle biopsy approach and results. The 41 patients were selected from more than 350 patients with diffuse lung disease. The criteria for selection are: chest radiograph or lung function, or both, suggestive of diffuse lung disease; possible occupational history of pneumoconiosis and exposure to inorganic dust; no other lung disease outside of the lung. 41 cases were divided into three groups: asbestos group, 16 cases, the main exposure to asbestos, the dust exposure period of 0.6 to 30 years (an average of 13 years), the first dust to lung biopsy interval of 8 to 34 years (average 22 years); silicon dioxide Group, 13 cases, the main contact with quartz, dust exposure period of 5 to 42 years (average 20 years). Dust from the first time to the interval 14 to 49 years (average 26 years); mixed dust group, 12 cases, contact with quartz, coal, iron, asbestos and talc and other mixed dust, dust
