Ewing’s Sarcoma: About a clinical case

Abstract

Various pediatric solid tumors present as small round cell tumors that make their morphological diagnosis difficult. Among these are extraosseous Ewing's Sarcoma (ES). Extraosseous epidural ES are extremely rare, with only 32 cases reported in the literature in 2017. We describe the atypical presentation of the case of a 17-year-old male adolescent, who presented with an LOE in the lumbar region of the spine, with extraosseous epidural origin, whose histological characteristics call it SE, with an infrequent location in these neoplasms. Frequently, the time from the first symptom to the diagnosis of Ewing's sarcoma is long, with a median interval of 2 to 5 months, in this case we see an incidental finding after trauma, being a localized lesion, it was possible to diagnose for its subsequent surgical resolution, thus helping to reduce the chances of metastatic disease.
