Summary
This case report details extraskeletal Ewing's sarcoma in the masseter muscle. Aggressive, multimodal treatment including chemotherapy, surgery, and radiation offers the best prognosis for these rare tumors.
Area of Science:
- Oncology
- Surgical Oncology
- Head and Neck Surgery
Background:
- Extraskeletal Ewing's sarcoma (EES) is a rare malignant bone tumor.
- EES commonly affects the trunk and extremities, but rarely occurs in the head and neck region.
Observation:
- A case of EES originating in the masseter muscle with mandibular invasion is presented.
- The patient underwent induction chemotherapy, salvage surgery, and free flap reconstruction.
Findings:
- Ewing's sarcoma of the masseter muscle is rare and challenging to diagnose and manage.
- Aggressive, multi-modal treatment including chemotherapy, surgical resection, and irradiation is crucial for optimal outcomes.
Implications:
- This case underscores the importance of considering rare diagnoses in head and neck masses.
- Advanced reconstructive techniques are vital for restoring function and aesthetics after extensive tumor resection.
- Multidisciplinary management is key for improving prognosis in extraskeletal Ewing's sarcoma.
