Ewing sarcoma is classified as Ewing’s sarcoma of the bone tissue, extraskeletal Ewing’s sarcoma, peripheral primitive neuroendocrine tumor, malignant small cell tumor of the thoracopulmonary region (Askin) and non-typical Ewing’s sarcoma. Extraosseous Ewing’s sarcoma may be seen throughout the body, however only reported at 4% in the neck. In our case patient has a painless mass growing on his posterior neck for 3 months.On the magnetic resonance imaging, a well-defined, encapsulated, well-demarcated mass lesion between the perivertebral muscles and the subcutaneus fat tissue was detected. Tumor was surgically resected and diagnosis was pathologically Ewing’s sarcoma. 22q11 translocation was detected in the molecular examination. Extraosseous Ewing sarcomas are rarely seen soft tissue masses. Although imaging features are not sufficient to make a specific diagnosis, it is important take the biopsy from the appropriate place and staging the tumor. In addition, complete surgical resection has been shown to associated with better survival rates compared to other Ewing sarcoma family. For this reason, imaging has an important role in the guidance of surgery and resectability of the tumor. Young patients with a fast growing, palpable mass should be evaluated carefully. Although the tumor is thought to be morphologically benign in the first, ekstraosseous Ewing’s sarcoma must be considered in the differential diagnosis of head and neck soft tissue masses.
