Renal cell carcinoma in childhood: report of one case

Renal cell carcinoma is extremely rare in children. A case is reported here of renal cell carcinoma in a seven-year-old boy whose clinical manifestations were fever and right loin pain. Imaging studies revealed a solid mass in the right kidney and a metastatic nodule over the middle lobe of the right lung. Right nephrectomy and middle lobectomy of the right lung were performed. Pathologic examination revealed a renal cell carcinoma with predominance of clear cells. Despite Stage IV, the patient is still alive without chemotherapy and radiotherapy. It should be emphasized that renal cell carcinoma should be included in the differential diagnosis of pediatric renal solid masses, particularly in older children and adolescents.
