title: A solitary metastatic lung tumor from thyroid papillary carcinoma diagnosed by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA): report of a case.
abstract: A solitary metastatic tumor from thyroid papillary carcinoma is rarely diagnosed preoperatively. A 61-year-old woman was referred to us for investigation of a solitary nodule in the right lung field on a chest X-ray, several years after a right hemithyroidectomy for thyroid carcinoma. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) of a tumor in the right lower lobe, adjacent to the inferior pulmonary vein, revealed metastasis of thyroid papillary carcinoma. Immunohistochemical examination of histological cores obtained from the EBUS-TBNA proved extremely helpful in confirming the diagnosis. We performed right lower lobectomy with lymph node sampling, and the final pathological diagnosis was papillary carcinoma without lymph node metastasis.
