A case of renal cell carcinoma presenting with paraneoplastic syndrome is reported. A 69-year-old man with uncontrolled diabetes was incidentally found to have a left thoracic tumor and a right renal tumor. He had intermittent fever of 39℃ or more and laboratory data showed diabetes and high C-reactive protein level. A radical nephrectomy was performed, but the neoplastic syndrome did not improve. After a second surgery consisting of complete resection of solitary bone metastasis the symptoms resolved immediately. At 6 months postoperatively, he had no reoccurence. Generally prognosis of patients with bone metastasis from renal cell carcinoma has been said to be poor, but surgical control of bone metastasis may be a key factor for the prognosis of patient with metastatic RCC in the era of targeted therapy.
