Abstract
Paratesticular rhabdomyosarcoma is a rare but aggressive malignancy in children and adolescents. Prognosis is related to initial tumor resectability as well as staging of the disease based on tumor invasiveness, tumor bulk, nodal disease and metastases. We report the unusual presentation of paratesticular rhabdomyosarcoma with metastatic extension through the inguinal canal and encasement of the abdominal aorta. These features portend a poor prognosis given their association with a greater stage of disease and unresectable nature at presentation. Delayed surgical resection follows a regimen of chemotherapy and radiation therapy in such cases of extensive disease. Encasement of the abdominal aorta has been shown to increase presurgical risk for intraoperative vascular injury when related to other malignancies, but its role in relation to metastatic paratesticular rhabdomyosarcoma has not been investigated. Also, rhabdomyosarcoma should be considered in the differential diagnoses of tumors that demonstrate encasement of the abdominal aorta.
