Abstract
Ewing¡¯s sarcoma is an uncommon malignant neoplasm of the long bone and it has a poor prognosis due to its early metastasis and aggressive local spread. It is mostly found before the age of 30 and it is rare in extraskeletal sites. Extraskeletal Ewing¡¯s sarcoma has been reported to occur in various sites including the larynx, scalp, nasal fossa, neck, chest wall, lung, pelvis, perineum, arm, finger, leg and toe, but it is extremely rare as a primary epidural tumor of the spine. We experienced a case of extraosseous epidural Ewing¡¯s sarcoma arising in the lumbar spinal canal at L3-L5 level in a 9-year-old boy. Following total laminectomy from L3 to L5 with a lumbar vertebrae and mass excision, he received chemotherapy with complete remission.
