Renal tumors (for the purposes of this article taken to broadly mean neoplastic lesions) should be distinguished from renal pseudotumors.
Whilst renal tumors can be broadly divided into primary and secondary (metastatic), benign and malignant, or adult and pediatric tumors, they are more formally and comprehensively classified according to the WHO classification of tumors of the kidney.
