Abstract

Rhabdomyosarcoma is the most common sarcoma of children and adolescents. Rhabdomyosarcoma is a highly malignant soft tissue sarcoma that can arise in any site of the body containing striated muscle or its mesenchymal analogue. The common primary sites were head and neck including orbit, extremities, genitourinary tract, trunk, retroperitoneum, gastrointestinal tract, and thorax. There are basically three types of rhabdomyosarcoma: embryonal, alveolar, and pleomorphic; these categories may overlap histologically. Retroperitoneal rhabdomyosarcoma of embryonal type is rarely reported in an adult. Since we experienced a case of 25 X 20 X 12cm-sized retroperitoneal rhabdomyosarcoma of embryonal type, we report this with a review of literatures.
