Renal medulla carcinoma in a white adolescent.

R enal medulla carcinoma is a recently described rare, aggressive tumor of the kidney occurring in patients younger than those in whom renal cell carcinoma occurs. To our knowledge, renal medulla carcinoma has been reported only in individuals of African descent carrying the sickle cell trait or afflicted by hemoglobin SC disease [1, 2]. We report what is, to our knowledge, the first case of renal medulla carcinoma occurring in a white child without a history of sickle cell disease or trait.
