[Anatomic and clinical features of a case of synoviosarcoma]

An asymptomatic patient presented a pulmonary metastatis of a synovial sarcoma 15 years after resection of the primary tumor localized in the right groin area. The pathology findings demonstrated the non-specific variable nature of the biphasic epithelial and mesenchymatous feature of such tumors. No treatment was initiated and the patient has remained asymptomatic after five years follow-up. Lack of change in the radiological images led us to re-examine the prognosis and treatment in light of data in the literature.
