Primary Ewing's sarcoma of the squamous part of temporal bone in a young girl treated with adjuvant volumetric arc therapy.

Ewing's sarcoma (ES)/peripheral primitive neuroectodermal tumors usually arise in the long bones of children and young adults. Primary ES of the cranium is unusual. Treatment involves multi-modality therapy incorporating surgery, radiotherapy and chemotherapy; outcomes are similar to those arising from long bones. We report a case of Primary ES of the squamous part of temporal bone with intracranial extension in a 9-year-old girl who was treated with surgery, chemotherapy followed by adjuvant radiotherapy by volumetric arc therapy. Post 1-year of treatment the girl is performing well in her classes.
