title: Ewing sarcoma of the jaws.
abstract: Three cases of Ewing sarcoma in the jaw bones are presented. The first patient is a 43-year-old woman with a rapidly growing tumor in the hard palate. The second patient is a 9-year-old girl with tumor in the left mandibular ramus and body. In both patients, the tumors were excised with significant safe margins. However, postoperative histopathologic evaluation revealed the presence of tumor cells in bony margins, necessitating a second surgery. The third patient is a 9-year-old boy with tumor in the right mandibular ramus and body. In patients 1 and 2, chemotherapy failed to control the tumor; however, in patient 3, chemotherapy resulted in significant shrinkage of the tumor and no further growth.
