title: Splenic and pulmonary metastases from renal cell carcinoma: report of a case.
abstract: We report herein the case of a patient in whom pulmonary and splenic metastases from renal cell carcinoma (RCC) were successfully treated by surgical excision. A 69-year-old man who underwent left nephrectomy for RCC 17 months before was suspected to have a pulmonary metastasis based on computed tomography (CT) findings. Partial resection of the left lower lobe was performed with thoracoscopic assistance. However, 4 months later, a splenic tumor, 6 cm in diameter, was detected by CT and ultrasonography, and a splenectomy was performed. Histologically, both resected specimens were diagnosed as metastasis from RCC. A second pulmonary metastasis of the left upper lobe was resected 4 years 8 months later. The patient was in good health when last seen 11 months after his last operation. Malignant neoplasms rarely metastasize to the spleen and most cases are found at autopsy, or feature multiple distant metastases. Only four other cases of splenic metastases from RCC have been reported. The prognosis associated with splenic metastasis is favorable when only a solitary lesion exists.
