title: Primary Ewing's sarcoma of the kidney with caval involvement: a case report.
abstract: Ewing sarcoma, also referred to as primitive neuroectodermal tumor (PNET), is a malignancy, histologically characterized by Homer-Wright rosettes and small round cells, that presents most commonly in bone or soft tissue in the pediatric and adolescent populations. We report the case of a patient that presents with intermittent gross hematuria, abdominal mass and elevated blood pressure. After surgical excision of the renal mass, the rare finding of a primary renal Ewing's sarcoma was discovered. After surgery the patient was additionally treated with chemotherapy. After presenting this case, we briefly discuss the unique case of isolated renal Ewing's sarcoma, including incidence and treatment.
