Abstract
INTRODUCTION: Primary clavicle tumors are uncommon and account for <1 % of primary bone tumors. The majority of primary clavicle tumors are malignant. Approximately 1.4 % of all cases of Ewing's sarcoma occur in the clavicle. CASE PRESENTATION: Here, we report the case of a patient diagnosed with Ewing's sarcoma who received neoadjuvant chemotherapy and had an important reduction in the tumoral volume; second, the patient had undergone partial resection of the medial clavicle, first rib, and the sternum. DISCUSSION: The survival rate of patients with nonmetastatic lesions is 56-79 %. The clavicle is connected to major anatomical structures, which makes surgery challenging. Even if there is little morbidity after resection, these studies did not show the superiority of reconstruction. CONCLUSION: The location of Ewing's sarcoma in our patient indicated that the surgical approach was needed for large resection. The functional outcomes were excellent, with no signs of recurrence at the 2-year follow-up.
