title: [Pediatric Ewing sarcoma of the rib: role of neoadjuvant chemotherapy in tumoral shrinking and sterilization. A case report].
abstract: Ewing sarcoma is a rare tumor, which represents, nevertheless, the most common primary chest wall tumor in children. The management and prognosis of these tumors have markedly improved with the use of multimodal therapy including adjuvant chemotherapy, surgery and/or irradiation. A good response to chemotherapy often avoids the need for extensive local treatment without sacrificing local control or long-term survival. Here, we report a new case of a bulky rib Ewing sarcoma, well managed by neoadjuvant chemotherapy resulting in significantly tumor shrinking that allowed complete resection. At the histological examination of the specimen, there was only inflammatory and fibrosis tissues without viable tumoral tissue.
