BEDOYA, Gisel A et al. Primary extra-osseous Ewing sarcoma of the dorsal spine with spinal cord compression at diagnosis: Case report. Arch. argent. pediatr. [online]. 2019, vol.117, n.1, pp.e41-e46. ISSN 0325-0075.  http://dx.doi.org/10.5546/aap.2019.e41.

Extraosseous primitive neuroectodermal tumors are very rare neoplasms. Only a few cases have been published in the literature. This report is about a 9-year-old female patient whose clinical manifestations showed spinal cord compression, so different diagnosis should be considered, including oncology disease. The patient showed a mass of the dorsal spine with spinal cord compression. She was diagnosed with Ewing Sarcoma after surgical intervention and pathology study. It is necessary to highlight the importance of the present case due to the low incidence of the extraosseous Ewing Sarcoma, and its infrequent location at the dorsal spine and the spinal cord compression as initial presentation of pediatric cancer, as well as the poor information related to the best therapeutic strategy to treat this disease at this location.
