A Fatal Case of Primary Orbital Ewing's Sarcoma with Intracranial Extensions in a Six-year-old Girl.

Ewing's sarcoma (ES) is the second most common skeletal tumor seen in children and adolescents which typically involves the long bones and the axial skeleton. ES involving the orbits is extremely rare and can lead to serious consequences. Patients usually present with fever, localized bone pain which increases during the night time, and a visible mass, often with a preceding history of trauma. The diagnosis is confirmed with immunohistochemistry. Patient management involves a multidisciplinary approach with complete focal surgical excision of the tumor along with multiple chemotherapeutic agents and radiation therapy.
