Synovial sarcoma is a highly malignant soft-tissue tumor of mesenchymal origin that accounts for approximately 5.8% to 10% of all soft-tissue sarcomas1,2. Nearly 90% of these tumors are discovered in an extremity, with the majority involving the lower limbs1-3. Synovial sarcoma within the lumbar spine has been mentioned in only a handful of reports in the English-language literature4-9, typically as part of a case series or as the subject of study for various imaging modalities. Occurrence in the pediatric population at this location is even rarer. The purpose of the present report is to describe the case of a fourteen-year-old girl with lumbar synovial sarcoma and to document the treatment algorithm that was used. The patient was informed that data concerning the case would be submitted for publication, and she consented.
