Triple lung cancers in a patient with silicosis.
A case of pulmonary silicosis associated with triple lung cancers is presented. Two of the three tumors were unexpected clinically. The discussion deals with the diagnostic difficulty in radiological differentiation between the pneumoconiotic mass lesion and superimposed tumor shadows, as well as the possible causal relationship between the two conditions. From the practical point of view, elderly patients with pneumoconiosis should be carefully monitored for the development of lung cancer.
