Ewing′s sarcoma of the jaws with sunray appearance in sonography

Abstract

Ewing′s sarcoma (ES) is an uncommon malignancy that occurs usually in childhood. In most of the reported cases, the occurrence of this tumor is more in the mandible than the maxilla. A case of Ewing′s sarcoma of the mandible along with the maxilla is discussed. A complete clinical, radiographic, biochemical and histological evaluation was done, ultrasonography revealed a sunray pattern; microscopically, the tumor was composed of monotonous small round cells that exhibited immune reactivity for CD99 and vimentin. The patient was subjected to multi-agent chemotherapy. This case elucidates the importance of professional knowledge of the relevant aspects of malignant lesions, such as ES. Although the prognosis remains poor, an increased rate of survival is now associated with early diagnosis and combined therapy.
