[Surgical treatment for metastatic lesions from renal cell carcinoma]

We report our experience on operations for solitary metastasis from renal cell carcinoma. Two cases had bone metastasis, and 2 cases brain metastasis. In 3 cases, the symptoms from the metastasis had remained absent for several months after the operation. One case was cancer-free for 2 years. Surgical treatment was useful for the solitary metastasis from the renal cell carcinoma. We examined both the primary lesion and metastatic lesion histopathologically. Pathological findings revealed grade-up and change of cell subtype in metastasis.
