Pediatric Renal Adenocarcinoma: A Review of Our Series

Abstract

To report our experience with pediatric renal adenocarcinoma. We conducted a retrospective review of renal adenocarcinoma cases from 1971 to 2006. We treated 154 patients with renal tumor, 4 (2.6%) of whom had adenocarcinoma. The mean age of presentation was 8.5 years (range, 2-15 years). Three patients were female and 1 was male. The most common histologic subtype was clear cell carcinoma. Three patients were diagnosed as stage IIIB and one as stage II, according to Robson's classification. All patients were treated with radical nephroureterectomy. One patient died of disease and the other 3 are currently disease-free. Adenocarcinoma is an uncommon histopathologic type of pediatric renal tumor. In patients with hematuria and abdominal or flank pain, we should consider this tumor as a possible diagnosis.
