RESUMEN
Background: Synovial sarcoma is a soft tissue tumor with a high degree of local and metastatic invasion. Case report: We report a 26 years old smoker woman with a history of a synovial tumor excised from the right thigh, who required a hip prosthesis for a pathological fracture due to metastases. Two years after, a lung metastasis in the left upper lobe was excised and treated with chemo and radiotherapy. Two years later a new lung nodule was found and excised. Pathology confirmed that they were metastases of the primary tumor. Three months after this last excision, the patient is asymptomatic.
