Childhood Ewing Sarcoma of the Orbit.
In the span of the last 48 years, only 33 cases of children with orbital Ewing sarcoma have been reported. This study is to present 3 cases that were admitted to Children's Cancer Hospital Egypt 57357, during the period from 2009 to 2013. We have 2 cases treated using the hospital standard Ewing sarcoma treatment protocol, to completion, whereas the third discontinued treatment. All tumors have confirmed CD99 positivity, although translocation (11;22) was positive in 1 patient and negative in the third. With earlier diagnosis and adequate surgical resection and integration of chemotherapy and radiotherapy 1 patient survived for about 4 years, whereas the other 2 cases died due to disease progression or recurrence.
