In a series of 235 patients with testicular tumors 2 elderly patients (0.9%) had secondary testicular tumors: 1 from a renal cell carcinoma and 1 from an unclassified anaplastic neoplasm. The pathogenesis of intrascrotal metastases of renal carcinoma is demonstrated by angiography of the dilated spermatic vein. In a literature survey the incidence rate of secondary testicular tumors is found to range from 0.3 to 3.6%. 30 cases of intrascrotal secondaries of renal cell carcinoma have been identified in the literature.
在一组235例睾丸肿瘤患者中，有2例老年患者（0.9%）发生继发性睾丸肿瘤：1例源于肾细胞癌，1例源于未分类的间变性肿瘤。通过扩张的精索静脉血管造影证实了肾癌阴囊内转移的发病机制。在文献调查中，继发性睾丸肿瘤的发病率为0.3%至3.6%。文献中已鉴定出30例肾细胞癌阴囊内转移病例。
