    Abstract:
    Ewing's sarcoma/peripheral primitive neuroectodermal tumors (ES/pPNET) are a group of small round cell sarcomas that show varying degrees of neuroectodermal differentiation characterized by translocation involving the EWS gene. Uterine ES/pPNET is a rare entity. A 29-year-old Chinese female who presented with abdominal swelling and pain was diagnosed with a primary uterine ES/pPNET on the basis of clinicopathologic, immunohistochemical and fluorescence in situ hybridization (FISH) data. She was given a multimodal treatment, including neoadjuvant, 95% cytoreductive, chemotherapy and radiotherapy. The patient is currently alive with persistent disease after 18 months of follow-up. We emphasized the crucial role of molecular techniques in the differential diagnosis of small round cell tumors in this unusual location. Multimodal therapy may improve the outcomes of patients.
