Summary
(Sub)periosteal Ewing's sarcoma is a rare bone cancer originating outside the bone marrow. This report details three rare cases managed with neoadjuvant therapy and surgical excision.
Area of Science:
- Orthopedic Oncology
- Pediatric Oncology
- Skeletal Tumors
Background:
- Ewing's sarcoma is a malignant small round-cell tumor originating from mesenchymal cells.
- Typically, it arises within the medullary cavity of bone.
- Rarely, Ewing's sarcoma can originate in soft tissues or have a (sub)periosteal location.
Purpose of the Study:
- To report on three exceptionally rare cases of (sub)periosteal Ewing's sarcoma.
- To highlight the management of these rare tumors.
Main Methods:
- Review of three patient cases with (sub)periosteal Ewing's sarcoma.
- Treatment included neoadjuvant chemotherapy, radiation therapy, and wide surgical excision.
Main Results:
- Successful management of three rare (sub)periosteal Ewing's sarcoma cases.
- Demonstration of treatment efficacy with combined neoadjuvant therapy and surgery.
Conclusions:
- (Sub)periosteal Ewing's sarcoma is an extremely rare variant of a common pediatric bone tumor.
- Multimodal treatment including neoadjuvant chemotherapy, radiation, and wide excision can be effective for this rare presentation.
