EWING'S SARCOMA IN THE PREMAXILLA OF A PEDIATRIC PATIENT: A CASE REPORT

Abstract

In August 2019, a 5-year-old female pediatric patient was diagnosed with primary non-metastatic Ewing sarcoma. She began chemotherapy treatment in September 2019, ending in November 2019. Subsequently, she was referred to a head and neck specialist, where a tumor was observed in the upper anterior alveolar edge. A biopsy was performed which confirmed Ewing´s sarcoma and showed an infiltrate in the entire premaxilla without posterior or midface involvement. Surgery for tumor resection was performed in March 2020, with a conclusive biopsy of small and round cell malignant neoplasm, consistent with Ewing´s sarcoma, the surgical margins were compromised, thus requiring complementary radiotherapy treatment. The rehabilitation was performed with a polypropylene obturator prosthesis in the premaxilla region. The patient returned for a check-up, without complaints, and was able to express herself in an intelligible manner, with her stomatognathic functions in balance.
