Rhabdomyosarcoma of the urinary bladder in an adult: Case report and review of the literature.

Rhabdomyosarcomas with bladder involvement in adults is an extremely rare tumor with approximately 35 cases reported. Because of its rarity in adults the exact treatment modalities are not entirely clear. Treatment is based on Children's Oncology Group in RMS. There is no significant difference in stage, lymph node status, gender, and site between adults and children. The 5 year survival for pediatric RMS is 66% and for adults 22%. It is clear that our understanding and treatment of pediatric RMS is much greater than that of adult patients and the possible reason for these differences are discussed.
