Anatomic and clinical features of synoviosarcoma: a case report

An asymptomatic patient presented a pulmonary metastatis of a synovial sarc oma 15 years after resection of the primary tumor localized in the right gr oin area. The pathology findings demonstrated the non-specific variable nat ure of the biphasic epithelial and mesenchymatous feature of such tumors. N o treatment was initiated and the patient has remained asymptomatic after f ive years follow up. Lack of change irt the radiological images led us to r e-examine the prognosis and treatment in light of data in the literature.
