Summary
A rare low-grade fibromyxoid sarcoma in a 58-year-old woman caused back and leg pain. Treatment involved surgery and Cyber Knife therapy, with diagnosis confirmed by histology and immunohistology.
Area of Science:
- Oncology
- Surgical Pathology
- Radiation Oncology
Background:
- Low-grade fibromyxoid sarcoma (LGFMS) is a rare soft tissue tumor.
- Spinal involvement by LGFMS is uncommon, presenting diagnostic challenges.
Observation:
- A 58-year-old woman presented with low back pain radiating to the right leg.
- Imaging revealed a paravertebral mass with extension into the L4 neural foramen.
Findings:
- Histopathology showed a bland spindle cell sarcoma with characteristic giant collagen rosettes.
- Immunohistological findings supported the diagnosis of LGFMS.
- The tumor was primarily located in the right paravertebral area with neural foramen extension.
Implications:
- This case highlights the importance of considering LGFMS in the differential diagnosis of spinal tumors.
- Multimodal treatment including surgical debulking and Cyber Knife therapy may be effective.
- Further research into optimal management strategies for spinal LGFMS is warranted.
