 In this case report, we described a case of parotid metastasis from EGFR mutation-positive non-small-cell lung cancer. A 71-year-old woman was referred to our department for the evaluation of swelling in the right parotid region. Fine-needle aspiration cytology and MR imaging findings suggested the possibility of benign tumors such as myoepithelial tumors or pleomorphic adenomas. Subsequent histological evaluation of the pulmonary nodule led to a diagnosis of pulmonary adenocarcinoma. The parotid lesion was excised for histological diagnosis, and the final diagnosis revealed metastasis from EGFR mutation-positive non-small cell lung cancer.
