Abstract
A 75-year-old woman was referred to our hospital because of an abnormal shadow on a chest roentgenogram, and was diagnosed with lung cancer. Right upper lobectomy was performed, and the histopathological analysis showed that the cancer was papillary adenocarcinoma. Three years and 7 months after the first lung surgery, she underwent partial resection of two tumors in the left lung. The two tumors were pathologically diagnosed as small cell carcinoma with intrapulmonary metastasis and squamous cell carcinoma. Four years and 4 months after the first surgery, she again underwent partial resection of a tumor in the right lung. The tumor was pathologically diagnosed as squamous cell carcinoma. All three surgical treatments were successful, and the patient has been free from relapse and surviving for over 2 years since the last surgery.
