Metastatic carcinoma to the thyroid gland rarely is encountered in clinical practice; however, autopsy series have shown that it is not a rare occurrence. A case of adenocarcinoma of the colon with metastases to the thyroid is reported. A review of the literature reveals that melanoma, breast, renal, and lung carcinomas are the most frequent tumors to metastasize to the thyroid. Metastatic disease must be considered in the differential diagnosis of cold nodules on radionuclide thyroid scans, particularly in patients with a known primary.
甲状腺转移性癌在临床实践中很少见；然而，尸检系列研究表明这种情况并非罕见。本文报告了一例结肠癌转移至甲状腺的病例。文献回顾显示，黑色素瘤、乳腺癌、肾癌和肺癌是最常转移至甲状腺的肿瘤。在对放射性核素甲状腺扫描显示的冷结节进行鉴别诊断时，必须考虑转移性疾病，尤其是在已知有原发肿瘤的患者中。
