Background:

Ewing's sarcoma is a rare bone cancer typically affecting adolescents and young adults.
Extra-skeletal Ewing's sarcoma (ES) is an even rarer variant, with limited documented cases in the oral cavity.

Observation:

A 1.5x1.5cm soft tissue mass was identified in the right mandibular vestibule.
Radiographic imaging showed no mandibular bone involvement.
Microscopic examination revealed a malignant small round cell tumor with CD99 immunoreactivity, characteristic of Ewing's sarcoma.

Findings:

The patient underwent successful enucleation surgery under local anesthesia.
Histopathological confirmation of extra-skeletal Ewing's sarcoma of the oral soft tissue was achieved.
Post-operative follow-up at 13 months showed the patient to be symptom-free.

Implications:

This case highlights the importance of considering rare diagnoses like extra-skeletal Ewing's sarcoma in oral masses.
Early detection and surgical intervention can lead to favorable outcomes.
Further research into ES of the oral cavity may improve diagnostic and treatment strategies.
