title: Synchronous primary lung carcinoma and lung metastasis from extrathoracic carcinoma.
abstract: We present the cases of 2 patients in whom primary lung cancer was found unexpectedly when pulmonary resection was performed for metastatic lung cancer. The possibility of combined primary and metastatic carcinoma should be considered in patients with a diagnosis of multiple pulmonary metastases from extrathoracic tumor.
