title: Metanephric stromal tumor: a rare benign pediatric renal mass.
abstract: We report a rare case and description of a benign pediatric renal mass. To our knowledge, this tumor has never been described in urologic published reports. It is possible that the identification of this renal tumor could spare a child the toxic adjuvant chemotherapy that would be administered if confused with histologically similar tumors such as clear cell sarcoma of the kidney.
