Rhabdomyosarcoma, derived from the unsegmented undiffentiated mesoderm, accounts for approximately 5~10% of all solid tumors in children. It is the most common soft tissue sarcoma in children younger than 15 years. Survival for children with
rhabdomyosarcoma, like that for Wilms' tumor, has been greatly improved since the incorporation of chemotherapy into treatment program. With current miltidisciplinary regimens, the overall 2 year survival rate for children with rhabdomyosarcoma
approaches 70%.
A case of rhabdomyosarcoma with retroperitoneal metastasis is reported. A 20-year-old male was hospitalized because of scrotal mass, with was more enlarged after blunt trauma. At operation, paratesticular mass extending along the spermatic cord
was
removed. Pathologic finding of the tumor revealed rhabdomyosarcoma of embryonal type. Abdominal CT showed retroperitoneal metastasis. The patient has been treated with combined modality therapy for 16 months.
