Renal tumor metastasis from thyroid follicular carcinoma is very rare. Here, we present a 64-year-old woman with metastatic thyroid follicular carcinoma presenting as a primary renal tumor. The renal tumor was removed and revealed the origin of thyroid follicular carcinoma. Six months after the treatment of renal tumor, the patient was readmitted for the enlarged thyroid gland. The follicular carcinoma was revealed in the resected thyroid gland. The serum thyroglobulin level and thyroid function tests were consistently normal. Although with metastasis to the kidney, thyroid follicular carcinoma is thought to have a good prognosis.
甲状腺滤泡癌的肾转移非常罕见。在此，我们报告一名64岁女性，其转移性甲状腺滤泡癌表现为原发性肾肿瘤。切除肾肿瘤后发现其起源于甲状腺滤泡癌。肾肿瘤治疗6个月后，患者因甲状腺肿大再次入院。切除的甲状腺中发现了滤泡癌。血清甲状腺球蛋白水平和甲状腺功能检查一直正常。尽管发生了肾转移，但甲状腺滤泡癌被认为预后良好。
