Abstract
BACKGROUND: Synovial sarcoma (SS) of the spine is a rare malignant soft-tissue tumor, and there are few reported cases. The aim of this paper is to report a rare case of spinal SS involving the paraspinal muscles, and to review all such cases reported in the literature. CASE DESCRIPTION: In this paper, we report a rare case of spinal SS involving the paraspinal muscles in a 12-year-old girl. The patient underwent surgical excision of the mass with adjuvant radiation and chemotherapy. At the 1-year follow-up, there was no evidence of local tumor recurrence, and the patient's symptoms had improved. In addition, we identified and reviewed 33 reported cases of SS involving the spine. CONCLUSION: Due to the limited number of reported cases in the literature, it is difficult to predict the outcomes of spinal SS. Further, different treatment modalities have been used to treat spinal SS. However, most of the reported cases had poor outcomes. Therefore, prospective multi-center studies are needed to further investigate the treatment strategies and outcomes for patients with spinal SS.
