A patient with asbestos-induced lung cancer complicated by silicosis.

A 76-year-old male died of lung cancer. At first, he was diagnosed as a silicosis, because he had worked for 30 years as a caster in shipyard and large opacities detected by chest x-ray and CT scanning. After the operation of lung cancer, numerous asbestos bodies were observed in the operated lung tissues. The detailed occupational inquiry revealed his asbestos use as a caster in shipyard. Early stage of asbestosis was suspected by chest CT scanning, but not definitely diagnosed in premortal examinations. Asbestosis, pleural plaques, silicosis and large cell carcinoma of the lung were histopathologically confirmed at the autopsy. A patient with asbestos-induced lung cancer complicated by silicosis was rarely published in the literature.
