Abstract |
Metastatic carcinomas to the thyroid gland are rare, and thyroid involvement by secondary carcinomas commonly results from direct the extension of malignant cells from adjacent organs such as the larynx or the trachea. The common primary sites of thyroid metastasis are kidney, breast, lung, and lymphoid tissue. Among head and neck cancers, nasopharyngeal carcinoma has a relatively high incidence of distant metastases to other sites and commonly involving sites are bone, lung, and liver.
Recently, we experienced a case of a 43-year-old male who had been presented with neck mass for 3 months. He was diagnosed non-keratinizing nasopharyngeal carcinoma in 1993. And, thyroid metastasis of nasopharyngeal carcinoma was confirmed by total thyroidectomy. So we report this rare case with the review of literatures. |
