Abstract
Primary Ewing's sarcoma arising from frontal bone is rare. We report a case of 17-year-old
boy with painless swelling in the frontoparietal region. Computed tomography showed
destruction of bone and an enhancing extradural mass. The patient underwent wide excision
combined with radio and chemotherapy. Histopathology revealed it to be round cell
sarcoma, and immunohistochemistry confirmed it to be Ewing's sarcoma.
