Abstract

ES has poor prognosis because of uncontrolled metastatic potential making early diagnosis and intervention critical for survival of the patient. This paper reports a rare case of ES involving mandible in an 8-year-old girl with clinical, radiological, histopathological and immunohistochemical features.
