Background: Extraosseous Ewing sarcoma (EES) is a rare case that accounts for 20% of Ewing sarcoma cases. EES is the second most prevalent pediatric malignancy after peripheral primitive neuroectodermal tumors. EES mostly arise from soft tissue and extra-skeletal. Computed tomography (CT) and magnetic resonance imaging (MRI) are primary modalities for determining tumor location, characteristics, type, and extent of tumors. In addition, for presurgical management, radio intervention with arterial embolization is needed as a preoperative. Case Description: We present a case of a 15-year-old boy diagnosed with EES. He had a “horn-like” tumor that grew progressively on his right ear over 5 months. Head CT scan and MRI were conducted to assess the extent. Embolization was performed before surgery. The surgery was conducted to excise the tumor radically. The histology pathology examination showed EES. Conclusion: EES rarely occurs in the head and neck. This may manifest as a solid mass with bleeding components that destroy the nearby bones, with exophytic mass. Imaging is important for early finding and detecting complications of EES.
