Primary Ewing Sarcoma of Frontotemporal Bone in Geriatric Patient.

Abstract

Ewing sarcoma is a rare primary malignant bone tumor, which mainly affects children and adolescents. Calvarial bone involvement and its appearance in elderly patients are extremely rare. We presented a 68-year-old female patient with headache and right frontotemporal swelling. Imaging studies showed a right frontotemporal mass expanding to the Sylvian fissure. The patient underwent total resection of the mass, and pathologic evaluation ensured the diagnosis of primary Ewing sarcoma. The patient had adjuvant radiotherapy and chemotherapy after surgery. Prognosis and efficiency of treatment for primary Ewing sarcoma of skull are unclear in elderly patients because of the sarcoma's rare appearance. Therefore more clinical evaluation is necessary. This case is the oldest patient presented in the literature.
