Synovial sarcoma of the nasal cavity and sinus are rare,comprise less than 0.1% of all soft tissue malignancies.Synovial sarcoma is a malignant mesenchymal tumor with variable epithelial differentiation,which is defined by the presence of a specific chromosomal translocation that generates SS18-SSX fusion oncogenes.The treatment include surgery,radiotherapy,chemotherapy.As the delicate anatomy of the nasal cavity and sinus limits the ability to obtain wide surgical margins.This maybe the reason why there is a higher local recurrence rate and worse disease-specific survival in head and neck sarcomas compared to other sites.
