PASCUAL SAMANIEGO, M. et al. Synchronous metastases of the spermatic cord from papillary renal cell carcinoma. Actas Urol Esp [online]. 2007, vol.31, n.4, pp.404-410. ISSN 0210-4806.

Papillary renal cell carcinoma has been related with higher survival rate and lower metastatic cancer mortality rate than clear renal cell carcinoma. We present an aggressive case related to unusual features for this histological type, like a tumor size higher than ten cm, great perirrenal fat and suprarenal gland infiltration, tumoral thrombosis of the infrahepatic cava vein, retroperitoneal adenopatic tumoral infiltration, high nuclear grade and synchronous solitary distant organ metastases of the right spermatic cord, finding three previous cases in the literature with this last feature. Prognostic implication of the papillary renal cell carcinoma type is unclear in cases like this, so probably we need better molecular and cytogenetic studies to get a correct classification of this histological type.
