Abstract
Introduction
Renal Ewing sarcoma is an aggressive and rare malignancy affecting children and adolescents. Limited data on its management contribute to uncertainties in treatment.
Case description
We present two pediatric cases of renal Ewing sarcoma. Both cases emphasize the significance of accurate diagnosis, multimodal treatment, and longterm follow-up in achieving favorable outcomes. Accurate diagnosis of renal Ewing sarcoma is crucial for effective management. Multimodal treatment involving neoadjuvant chemotherapy, surgical resection and staging with lymph node sampling, and chemotherapy continuation has shown promising results in our cases. Long-term follow-up is essential for monitoring disease progression and ensuring optimal outcomes.
Practical Implications
There is limited data published about these renal tumors, especially in the pediatric population, and most studies lack longterm follow-up, with uncertain management due to limited data. This data will add to the newer, multimodal approach and form the basis for future meta-analysis to help formulate guidelines for upcoming international meetings. Continued research efforts are necessary to optimize strategies and improve the prognosis for pediatric patients with renal Ewing sarcoma.
