Renal carcinoma, the third most common urological cancer, induces presence of metastases in 75% of cases. The most affected sites for metastasis are the lungs, the lymphatic system, bones, the liver, adrenal glands and the brain with sometimes a cancer free period of several years prior to evolutionary recurrence of the disease. The aim of this literature review is to report on secondary uncommon renal localizations by underlining their clinical significance, as well as main characteristics, in order to provide guidelines for effective patient diagnosis and therapeutic management.
