Description

Renal cell carcinoma (RCC) is rarely associated with mediastinal and hilar lymph node metastasis without lung metastasis. We report a 42-year-old man with metastatic RCC who subsequently underwent surgery for lymph node metastasis. Initially, a right nephrectomy had been performed for RCC. At follow-up five years later, a left lower mediastinal tumor of 2.5 cm was identified on surveillance computed tomography (CT). This tumor was surgically excised. The pathological diagnosis was lymph node metastasis from RCC. However, follow-up chest CT several months later revealed right hilar lymph node enlargement without evidence of systemic metastasis. The hilar lymph node was then removed by thoracotomy. The pathological diagnosis was also lymph node metastasis from RCC. Now, at two years after his last surgery, the patient is doing well. This case suggests that even with isolated mediastinal and hilar lymph node metastasis from RCC, favorable outcomes are possible with surgical resection.
