Clear cell renal cell carcinoma (ccRCC) is known to display synchronous and metachronous metastases to a diverse set of organs. Retrograde and contralateral metastases of ccRCC are rare, with few cases in the literature. The mechanism of spread in these cases is thought to be facilitated by either the direct extension of tumor into the renal and gonadal veins or by the vertebral venous plexus. Here, we present a rare case of contralateral and retrograde ccRCC metastasis with extensive venous involvement.
已知透明细胞肾细胞癌(ccRCC)会出现向多种器官的同时性和异时性转移。ccRCC的逆行性和对侧转移很少见,文献中仅有少数病例。这些病例的扩散机制被认为是肿瘤直接延伸至肾静脉和性腺静脉,或通过椎静脉丛促成的。在此,我们报告一例罕见的伴有广泛静脉受累的对侧和逆行性ccRCC转移病例。
