Three cases of malignant tumor metastasis to primary renal cell carcinoma (RCC) are described. We review the literature on this subject and emphasize the possible mechanisms of this observation in 46 patients described in the English literature. RCC is the most common tumor recipient of metastasis while carcinoma of the bronchus is most consistently the metastatic donor. This phenomenon is not as infrequent as previously thought and may be present in up to 15 per cent of patients with simultaneous RCC and second neoplastic disease.
本文描述了3例原发性肾细胞癌（RCC）发生恶性肿瘤转移的病例。我们回顾了关于该主题的文献，并着重阐述了英文文献中所描述的46例患者出现这一现象的可能机制。肾细胞癌是最常见的转移瘤接受者，而支气管癌则一直是最常见的转移瘤供体。这种现象并不像之前认为的那样罕见，在同时患有肾细胞癌和第二种肿瘤疾病的患者中，其发生率可能高达15%。
