Distant metastasis of Papillary Thyroid Cancer (PTC) to the kidney(s), while rare, has been observed, with approximately 30 cases described in the literature. We present the case of a 28-year-old male who was diagnosed with metastatic PTC following resection of a solitary renal mass. Pathological analysis of the thyroid gland following subsequent thyroidectomy revealed positive regional lymph nodes consistent with metastatic PTC, however, no evidence of malignancy was identified in the thyroid gland. To our knowledge, this is the only known case of metastatic PTC involving the kidney in which no primary lesion was found in the thyroid gland.
甲状腺乳头状癌（PTC）远处转移至肾脏虽罕见，但已有相关报道，文献中描述了约30例病例。我们报告一例28岁男性病例，该患者在切除孤立性肾肿块后被诊断为转移性PTC。随后甲状腺切除术后甲状腺的病理分析显示区域淋巴结阳性，符合转移性PTC，但甲状腺内未发现恶性证据。据我们所知，这是唯一一例已知的转移性PTC累及肾脏且甲状腺内未发现原发灶的病例。
