Extraosseous Renal Ewing Sarcoma: The “Blue” Tumour in kidney
Introduction: Primary Ewing sarcoma (ES) is a distinctly rare tumour in the kidney and very limited cases were reported till date.
Case Presentation: Herein, we report a case of right renal ES in a young boy who presented with bleeding right renal tumour and underwent emergency right radical nephrectomy. Tumour cells are strongly positive for CD99 and FLI-1, thus confirming the diagnosis.
Conclusion: Therefore, this entity should always be one of the differential diagnosis while dealing renal masses in young population.
