Rhabdomyosarcoma of the kidney: A case report.

Rhabdomyosarcoma is a mesenchymal malignancy. It can occur anywhere in the body, but is extremely rare in the kidney. Here, we report a rare case of rhabdomyosarcoma of the kidney in a 19-year-old female who presented with right lumbar pain. Abdominal computed tomography (CT) suggested a huge retroperitoneal mass (approximately 18 × 14 cm). Preoperative neoadjuvant chemotherapy was performed through two preoperative cycle. After admission to our department for further evaluation, enhanced abdominal CT showed a mass of the right kidney (9.6 cm × 7.1 cm). The mass was successfully removed by surgery and the patient achieved a complete recovery.
