Secondary tumour to the kidney is quite frequent. Even if, theoretically, all solid tumours may give rise to renal metastasis, secondary lesions to the kidney occur more commonly in patients with lung and breast cancer, melanoma and lymphoma. Only 15 cases of renal metastasis arising from a follicular thyroid carcinoma have been reported in the literature. Rarely, metastases to the kidney present as primary renal tumours and may be treated surgically for that mistaken diagnosis. Nevertheless, in patients with solitary late distant metastasis of thyroid cancer, complete surgical resection may be proposed, followed by 131I ablation in order to offer a better chance of prolonged survival. We describe a case of a renal mass undergoing radical surgery and revealing itself as a solitary metastasis from follicular carcinoma of the thyroid, appearing 10 years after total thyroidectomy and 131I ablation therapy.
肾脏的继发性肿瘤相当常见。即使从理论上讲，所有实体瘤都可能引发肾转移，但肾继发性病变在肺癌、乳腺癌、黑色素瘤和淋巴瘤患者中更为常见。文献中仅报道了15例由滤泡状甲状腺癌引起的肾转移病例。肾转移瘤很少以原发性肾肿瘤的形式出现，可能会因误诊而接受手术治疗。然而，对于甲状腺癌孤立性晚期远处转移的患者，可考虑进行完整的手术切除，随后进行碘-131消融，以提高延长生存期的机会。我们描述了一例接受根治性手术的肾肿块病例，结果显示为甲状腺滤泡状癌的孤立性转移，发生在甲状腺全切除和碘-131消融治疗10年后。
