Renal cell carcinoma in childhood.

Renal cell carcinoma is extremely infrequent in children. We report a case of renal cell carcinoma in a 13-year-old male. Presenting manifestations were loin pain, fever, and weight loss. A palpable abdominal mass was found. Imaging studies showed a solid mass into the right kidney. Nephrectomy was performed and pathological examination demonstrated characteristic findings of renal cell carcinoma. This report emphasizes that renal cell carcinoma should be included in the differential diagnosis of renal masses in children.
