Ewing's sarcoma is an uncommon malignancy primarily affecting bone tissue and usually occurs in adolescents and young adults. This paper reports a rare case of extra-skeletal Ewing's sarcoma of the oral cavity soft tissue. In the clinical examination, a mass of 1.5×1.5cm in diameter was observed in the right mandibular vestibule. Radiographic examination revealed no involvement of mandible. Microscopically, the tumor was composed of malignant small round cell tumor that exhibited immunoreactivity for CD99. Enucleation surgery under local anesthesia was performed for the patient and prognosis was excellent. The patient remained symptom-free after 13 months of follow-up.

Background: GALOP investigators developed a prospective cooperative protocol for localized Ewing sarcoma (ES) incorporating interval-compressed chemotherapy (VDC/IE, vincristine, doxorubicin, cyclophosphamide/ifosfamide and etoposide). After completing conventional treatment, patients were randomized to 1 year of metronomic chemotherapy (vinblastine and cyclophosphamide).
Methods: Phase III randomized prospective trial.

Background: Several studies have shown that the intensity of treatment in Ewing sarcoma has an impact on outcome. The present trial tested the non-inferiority of intensive, shorter, induction chemotherapy (25 weeks total treatment time) compared to the standard treatment (37 weeks) in non-metastatic Ewing sarcoma (ES) at onset.
Procedure: This national, multicenter, parallel, randomized, controlled, open-label, non-inferiority, phase III trial was conducted in 14 specialized hospitals in Italy.
