Giant Primary Epidural Extraskeletal Ewing Sarcoma in Cervical Spine of an Infant: Case Report and Review of the Literature.

Ewing sarcoma (ES) is a highly malignant tumor originating from bones, exceptionally long bones. ES arising from the epidural extramedullary space, primarily the cervical region, is highly unlikely. There have been only six cases of cervical epidural extraskeletal Ewing sarcoma (EEES) in children reported in the literature, all of whom were older than seven years old. Four of seven cases, including the one mentioned in this study, were male (57%). Herein, we report a 1.5-year-old girl who presented with quadriparesis without cognitive impairment and had initially undergone a metabolic disorder evaluation. The spine MRI revealed a mass in the C2-T6 region, and she underwent a biopsy of the tumor via laminectomy. Microscopic examination confirms a diagnosis of ES based on immunohistochemistry. This is the first literature that presents an infant with EEES.
