Ewing’s sarcoma of the kidney : a rare tumor in children

الملخص EN

Ewing’s sarcoma of the kidney is a rare malignancy, especially in the pediatric population.

it belongs to what is called the Ewing sarcoma family tumors.

it is not common as a differential diagnosis in renal tumors during childhood, with a nonspecific presentation as abdominal pain and hematuria.

it is usually seen in late childhood and adolescent patients.

the radiological features are neither specific nor pathognomonic.

so, we rely on histopathology, immunohistochemistry and molecular/ cytogenetic studies for diagnosis.

once the diagnosis is established, multimodal chemotherapy is started according to the treatment protocols found in the literature and centers’ experiences in these cases.

reporting and publishing these rare tumors will help in understanding the course of the disease and its response to the treatment protocol.
