ABSTRACT
Tumors of the kidney account for fewer than 8% of childhood neoplasms. Although the great majority of these are embryonal (mostly Wilms) tumors, other malignancies also may be seen. Both the primary lesion and the eects of therapy have implications for the treating pediatric nephrologists. A clinicopathologic classication of renal tumors in children shown in Table 50.1 provides a framework for discussion in this chapter. It is likely that emerging genetic and molecular data may be instrumental in therapeutic and prognostic classication of these malignancies in the future.
