Summary
A primary mediastinal myxoid liposarcoma was successfully removed via sternal resection. Reconstruction using a methylmethacrylate sandwich technique allowed for a two-year disease-free survival, despite initial inflammation.
Area of Science:
- Thoracic surgery
- Surgical oncology
- Orthopedic reconstruction
Background:
- Primary mediastinal myxoid liposarcoma (PML) is a rare tumor.
- Complete surgical resection is the primary treatment modality.
- Sternal involvement necessitates complex reconstruction strategies.
Observation:
- A 34-year-old patient presented with a grade I myxoid liposarcoma involving the sternum.
- Sternal resection was performed for complete tumor extirpation.
- Methylmethacrylate sandwich technique was employed for sternal reconstruction.
Findings:
- Postoperative persistent inflammation required partial removal of the methylmethacrylate device.
- Two-year follow-up revealed no evidence of local recurrence.
- No distant metastases were detected at the two-year mark.
Implications:
- Sternal resection and methylmethacrylate reconstruction can achieve oncological control for mediastinal liposarcoma.
- Management of postoperative complications, such as inflammation, is crucial for successful outcomes.
- Long-term surveillance is essential to monitor for recurrence in these rare tumors.
