Abstract
A case of 72-year-old man with double primary synchronous lung cancers was reported.
Clinical symptoms were cough, bloody sputum, and chest pain. Radiological findings of chest were abnormal shadows such as atelectasis of right lower lobe and an irregular coin lesion of left lower lobe. The results of cytological study of sputum, and histological study of specimen from tumor of right bronchial tree by bronchofiber-scopy were consistent with squamous cell carcinoma. Moreover, the specimen obtained from tumor of left lower lobe by percutaneous needle biopsy revealed small cell carcinoma cytologically and histologically. From these findings we confirmed the patient had double primary lung cancers.
The literature was reviewed.
