Ewing sarcoma (ES) is a tumor of neuroectodermal origin. ES mainly affects children and adolescents and is rare in head and neck region. A 3-year-old boy was referred for investigation of swelling in the maxilla. According to his mother, 8 days prior to our consultation, the patient was evaluated by a doctor who prescribed amoxicillin-clavulanate. However, the lesion did not regress and increased over time. Intraoral examination revealed a mass in the right posterior region of the maxilla, extending to the hard palate and tuber. Indefinite limits, softened consistency, and painful symptoms were observed. Panoramic radiography revealed bone destruction with ill-defined limits in the right maxilla. The diagnostic hypotheses included lymphoma and sarcoma. A biopsy was performed, and microscopic evaluation showed a malignant neoplasm composed by small, round, and blue cells. Immunohistochemistry staining was positive for CD99. Clinical and immunohistochemical features favored the diagnosis of ES. The patient was referred for oncological treatment.
