Ewing's sarcoma is a part of a rare group of malignant neoplasms, whose pathological morphological features are small round cells. Extraskeletal Ewing's sarcoma is a more uncommon primary tumor. Herein, we report the case of a 66-year-old man who complained of chest tightness. Subsequent chest CT scans revealed an irregular and uneven density mass on the right side of the anterior mediastinum with invasion of the superior vena cava, pericardium and right lung. The patient's clinical symptoms were improved after performing excision of the mediastinal lesions under cardiopulmonary bypass. Based on histological and immunohistochemical findings, the tumor was diagnosed as extraskeletal Ewing's sarcoma.
尤因肉瘤是一组罕见的恶性肿瘤的一部分，其病理形态学特征为小圆细胞。骨外尤因肉瘤是一种更罕见的原发性肿瘤。在此，我们报告一例66岁男性患者，其主诉为胸闷。随后的胸部CT扫描显示前纵隔右侧有一个密度不均匀的不规则肿块，侵犯上腔静脉、心包和右肺。在体外循环下切除纵隔病变后，患者的临床症状有所改善。根据组织学和免疫组化结果，该肿瘤被诊断为骨外尤因肉瘤。
