Abstract:
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.
