Maxillary Ewing′s sarcoma: A report of innocuous lesion with nocuous pathology

Abstract

Ewing′s sarcoma represents a highly lethal and a rare malignancy, which predominately prevails in the long bones and skeleton. Its occurrence in the oral cavity has been estimated to be 1-2% of the overall reported cases. The common presentation of this malignancy overlaps with that of other malignant lesions affecting the jaws. Early diagnosis and treatment initiation improves the overall prognosis, even though the estimated survival rate is 5 years in approximately 4-7% of the patients following therapy. Treatment in concordance to other bone malignancies such as osteosarcoma and chondrosarcoma has been tried and is known to improve and prolong the survival rate. Here, we report a case of this rare malignancy occurring in the jaws with an unusual presentation as a common dental problem of an unhealed and infected extraction socket.
