Metastasis of Laryngeal Carcinoma to the Thyroid Gland

Abstract

A rare case of metastasis of laryngeal carcinoma to the thyroid gland was reported. The patient was a 60-year-old male, who had received radiotherapy for glottic T2NO carcinoma 6 months earlier. He complained of cervical lymphnode swelling and of a thyroid tumor. On, fine needle aspirationcytology, the tumor was diagnosed as metastatic squamous cell carcinoma. Histological examination showed the same histological type as the previous laryngeal carcinoma, which was moderately differentiated squamous cell carcinoma. Although a total thyroidectomy and a modified neck dissection were performed, he died of lung metastasis 5 months after the operation.
