title: Ewings' sarcoma of the mandible.
abstract: Ewings' sarcoma involving the facial bones is rare although it is the second most frequent bone malignancy. For the diagnosis a biopsy is needed. Currently the treatment is the combination of chemotherapy and radiotherapy with surgery indicated in only a few instances. We report a case of Ewing's sarcoma of the mandible and describe its clinicopathologic features and the treatment of this disease.
