Genitourinary rhabdomyosarcoma: unusual diagnosis presenting within hours of delivery.

Genitourinary rhabdomyosarcoma of the newborn is extremely rare. We present a case report of a newborn delivered with a palpable abdominal mass revealing rhabdomyosarcoma on biopsy. Prenatal care was normal. The child was treated with multimodal therapy including extensive chemotherapy, surgical excision, and radiation therapy. Surgical excision included cystoprostatectomy, ureterostomy, abdominoperineal resection and colostomy placement. He continued to progress and eventually succumbed to his disease.
