Ewing's sarcoma of the mandible.
Ewing's sarcoma of the mandible occurs rarely; there have been less than 50 reported cases in the past 30 years and none of these have been in the otolaryngologic literature. They usually present in the second decade of life with pain and swelling of the soft tissue overlying the mandible. The diagnosis can only be made by an adequate mandibular biopsy, although x-rays and clinical presentation are helpful. Current treatment consists of radiation therapy and sequential adjuvant chemotherapy.
