title: Asbestos exposure. An update on pleuropulmonary hazards.
abstract: Asbestos exposure is causally related to the development of asbestosis, bronchogenic carcinoma, malignant mesothelioma, and nonmalignant pleural disorders. Clinical and roentgenographic manifestations of asbestosis mimic other diffuse fibrotic lung diseases. However, a concomitant finding of pleural plaques strongly suggests the diagnosis. The manifestations of bronchogenic carcinoma related to asbestos exposure are varied and do not differ from those unrelated to asbestos exposure. Malignant mesothelioma signals previous asbestos exposure. Nonmalignant pleural disorders may not cause any symptoms but should alert the physician to other concurrent or potential asbestos-related diseases. To diagnose asbestos-related diseases, physicians should bear in mind the long latent period and should take a careful, comprehensive occupational and environmental history. Cigarette smoking markedly increases the risk for development of bronchogenic carcinoma in asbestos workers and increases the mortality due to asbestosis.
