Ewing's sarcoma of bone and soft tissues
1Division of Pathology, University of Texas M.D. Anderson Cancer Center, Houston 77030.
Summary
Ewing's sarcoma, a rare bone and soft tissue cancer, can occur in facial bones (2.5% of cases) and head/neck soft tissues (11% of extraskeletal sites). Combined treatment approaches have improved outcomes for this high-grade malignancy.
Area of Science:
- Oncology
- Pathology
- Skeletal Biology
Background:
- Ewing's sarcoma is a rare bone and soft tissue malignancy.
- It can originate within bone (intraosseous) or in soft tissues.
- Facial bone involvement is uncommon, representing 2.5% of all Ewing's sarcoma of bone.
Purpose of the Study:
- To highlight the occurrence and characteristics of Ewing's sarcoma in the facial bones and head and neck soft tissues.
- To emphasize the significance of extraskeletal Ewing's sarcoma in the head and neck region.
- To underscore the impact of multimodal treatment on managing this aggressive neoplasm.
Main Methods:
- Review of clinical and pathological data.
- Incidence rate analysis for facial bone and head/neck soft tissue Ewing's sarcoma.
- Evaluation of treatment modalities and their outcomes.
Main Results:
- Ewing's sarcoma in facial bones accounts for approximately 2.5% of all bone cases.
- The head and neck soft tissues represent 11% of extraskeletal Ewing's sarcoma sites.
- Combined modality treatment has shown efficacy in managing the high-grade malignancy.
Conclusions:
- Ewing's sarcoma has distinct intraosseous and soft-tissue presentations.
- The facial bones and head/neck soft tissues are specific sites for this rare sarcoma.
- Multimodal therapeutic strategies are crucial for improving outcomes in high-grade Ewing's sarcoma.
