Except for benign pleural effusion, asbestos-related pulmonary complications, including asbestosis, malignant mesothelioma and bronchogenic carcinoma, usually occur more than 20 years after exposure. Pleural plaques and pleural thickening serve as markers for asbestos exposure, but they are not associated with an increased risk of malignancy. ⋯ A history of dyspnea, pleuritic chest pain, fatigue, weight loss and pleural effusion in a former asbestos worker is suggestive of mesothelioma. Cigarette smoking greatly increases the risk of lung cancer in asbestos workers.
