Destructive radiolucent lesion involving right maxillary alveolus: Report of a rare case

Abstract

Ewing′s sarcoma/primitive neuroectodermal tumor (ES/PNET) usually arises in the long bones of extremities. It is uncommon to find ES in the head and neck region, particularly in gnathic bones. It comprises 6-8% of all primary bone malignancies. Only 1% of cases is reported with jaw involvement and has mandibular predilection. Even with early intervention, patients with metastasis have approximately 20% chance of 5-year survival. Here, we report a rare case of ES involving right maxillary alveolus.
