[Two cases of renal cell carcinoma detected by metastasis to another organ].
Two cases of rare metastases from renal cell carcinoma are reported. The first case was in a 44-year-old man presenting with left exophthalmos. Radiological examination revealed left renal tumor with metastases to paraaortic lymph nodes, left orbit, bone and lungs. Radical nephrectomy was performed. Pathological diagnosis was renal cell carcinoma, pT3aN2M1. The patient died of widespread pulmonary metastasis 5 months postoperatively. The second case was in a 59-year-old man with a complaint of tongue tumor. Histopathology of the enucleated tumor was suggestive of metastatic renal cell carcinoma. Computed tomographic scan revealed left renal tumor with regional lymph node metastasis. No other metastasis was found. Radical nephrectomy confirmed the pathological diagnosis of renal cell carcinoma, pT3bN1M1. He has been treated with interferon-alpha and has been free of recurrence for 10 months postoperatively.
