Surgical Resection with Boyd Technique for Metastatic Ewing Sarcoma of the Bone Plus Docetaxel/Gemcitabine, Associated with Improved Outcomes in Tumor Activity

Ewing sarcoma is a malignant bone tumor that mainly affects children, adolescents and young adults with more than 1.5 cases per million worldwide. Approximately 20-25% of patients present metastatic disease at the diagnosis, that is often resistant to intensive therapy.We present the case of a 19-year-old male with history of epilepsy who started his condition with weight loss, increased volume, pain, swelling after receiving surgical treatment due to a left distal femur fracture, showing tomographic evidence of a 50-cm tumor with multiple lung lesions, so disarticulation was performed with the Boyd technique, obtaining histopathological result of Ewing’s Sarcoma, and was subsequently sent to the medical oncology service for follow-up and adjuvant treatment with significant clinical and radiological improvement in pulmonary metastatic activity.
