In lung cancer, the mechanism of carcinogenesis has been elucidated, and several driver genes have been discovered [1]. Drugs that respond specifically to them have come to be used in clinical settings [1]. The epidermal growth factor receptor (EGFR) gene mutation is one of such driver genes. Non-small cell lung cancer (NSCLC) patients with control of bone metastases by EGFR tyrosine kinase inhibitors (EGFR-TKIs) have been reported [2]. NSCLC can metastasize to rare sites. We show herein a case with metastasis to thoracic spinous process from EGFR-mutated NSCLC....
