Abstract: Papillary thyroid carcinoma metastasizing to the kidney are extremely rare events, which may easily be misdiagnosed as renal cell carcinoma. The diagnosis needs to be based on immunohistochemical examination. We described a case of renal tumor to be proved renal metastatic carcinoma from thyroid origin by pathological examination. Computed tomography (CT) scan shows metastasis nodules in lungs. Following total thyroidectomy, he underwent iodine-131 ( 131Ⅰ), thyroid hormone and sorafenib to treat thyroid remnant tumor and metastases. Partial nephrectomy was conducted to remove the left renal metastatic carcinoma for preserving normal renal function. Follow-up revealed that partial pulmonary nodule gradually shrunk, and no new metastasis appeared.
