Metastatic cancer to the thyroid gland is uncommon. In this report we describe a patient with a malignant fibrous histiocytoma that metastasized to the thyroid, possibly to a preexisting thyroid nodule. A review of the literature reveals that breast and lung carcinoma are the most frequently identified sources of secondary thyroid carcinoma found at autopsy, while renal carcinoma comprises over 50% of secondary thyroid malignancies discovered clinically. A number of authors suggest that preexisting thyroid disease (i.e., multinodular goiter and thyroid nodules) may provide a nidus for metastases to the thyroid gland.
甲状腺转移性癌并不常见。在本报告中，我们描述了一名患有恶性纤维组织细胞瘤并转移至甲状腺的患者，可能转移至一个已存在的甲状腺结节。文献回顾显示，乳腺癌和肺癌是尸检时发现的继发性甲状腺癌最常见的原发部位，而肾癌占临床发现的继发性甲状腺恶性肿瘤的50%以上。许多作者认为，已存在的甲状腺疾病（即多结节性甲状腺肿和甲状腺结节）可能为转移至甲状腺提供病灶。
