title: [A case of lung metastasis of thyroid cancer with endobronchial polypoid growth].
abstract: A case of a 73-year-old woman, complaining of exertional dyspnea and hemoptysis, is reported. About twenty years earlier, she had been diagnosed as having a thyroid carcinoma and had undergone a partial thyroidectomy. Bronchoscopic findings showed an endobronchial polypoid tumor which obstructed the intermediate bronchus almost completely. The polyp was about 3cm in length and protruded from the entrance of the middle lobe bronchus. The histologic findings revealed it to be a metastasis of the papillary thyroid carcinoma. After a polypectomy, the hypoxemia and dyspnea showed remarkable improvement.
