Case Discussion

The presence of bilateral calcified pleural plaques is fairly specific for the diagnosis of asbestos exposure. Patients with asbestos exposure are at a 5-fold greater risk of developing lung cancer. There is a synergistic effect between asbestos exposure and smoking with a 55-fold increase in risk for lung cancer. Mesotheliomas are malignancies of the pleura that are associated with condition and are rarely found in people without asbestos exposure. Historically, occupations with high risk of exposure to asbestos include shipyard workers, auto mechanics, construction workers and other construction trades.
