Sclerosing epithelioid fibrosarcoma of the lumbar spine: a case report and review of the literature.

Sclerosing epithelioid fibrosarcoma (SEF) is a rare soft tissue tumour subtype, and those arising from the spine are even rarer. To the best of our knowledge, only 3 cases with the spine as the primary site of SEF have been previously reported. We report a 61-year-old female who presented with backache and bilateral leg numbness for 3 years, worsened over the last three months. Pathological fracture of the L1 vertebra was detected, and soft tissue density in the spinal canal and left vertebral body margin was also seen on contrast CT. She underwent tumour resection via a posterior approach, decompression, bone grafting, fusion, and internal fixation. Histology confirmed the diagnosis of SEF.
