Papillary adenocarcinoma of the renal pelvis in a child: case report and brief review of the literature.

Tumors of the renal pelvis are not common in adults and are extremely rare in children. Forty-eight cases of adenocarcinoma of the renal pelvis have been reported, with only one patient under 32 years of age. We report the youngest patient (an 11 year old boy) diagnosed with this tumor and discuss our approach to therapy. We also review the literature with respect to the characteristics and histogenesis of this rare neoplasm.
