Ewing's sarcoma of mandible.

Ewing's sarcoma is a highly malignant tumour which develops from the medullary tissue of bones. It accounts for four to five per cent of all primary bone tumours (Ackerman et al., 1968; Dahlin, 1978) and usually presents as a solitary lesion in patients below the age of 30 years. It is most commonly situated in a long bone of the upper and lower extremities, pelvis, ribs and vertebrae. We describe the clinico-pathological features and management of a 19 year old male patient who developed Ewing's sarcoma of the mandible, an uncommon site of origin. It is hoped that the improvement in prognosis of this tumour observed in other sites due to aggressive chemotherapy will also pertain for Ewing's sarcoma within the mandible. This case illustrates the difficulties of management at this anatomic site.
