title: [A case of severe pneumoconiosis with synchronous triple lung cancer].
abstract: A 70-year-old man who had worked in a stonepit for about fifty years was admitted to our hospital for detailed examination of the signs of pneumoconiosis (3/3, q) and a nodular shadow in the right upper lung field. Under a clinical diagnosis of lung cancer complicated with pneumoconiosis, right upper lobectomy with a right S6 resection was performed. Pathological examination revealed moderately differentiated adenocarcinoma of the right S2, well-differentiated adenocarcinoma of the right S6, and a squamous cell carcinoma of the right S1 which was not detected by chest CT. In addition to the difficulty of diagnosing lung cancer in a patient with severe pneumoconiosis, treatment for lung cancer may be limited by the poor pulmonary function that results from pneumoconiosis. Although the labor administration's decision that lung cancer patients with concomitant pneumoconiosis deserve compensation can be evaluated as a good one, the study of the relationship between pneumoconiosis and lung cancer needs further study through follow-up examination of pneumoconiosis cases.
