A case of extraskeletal Ewing's sarcoma arising in right lumbar region with involvement of epidural space is described in a 16 years old girl. The diagnosis of Ewing's sarcoma was done from cytochemical and electron microscopic studies which showed intra-cellular glycogen granules whereas cytologic and immunological analysis eliminated lymphoid malignancies. This case emphasized the interest of these techniques, adjunctive to routine light microscopic examination for the pursuit of a specific diagnosis in the small round cell neoplasm.
一名16岁女孩被诊断出右腰区发生骨外尤文肉瘤并累及硬膜外间隙。通过细胞化学和电子显微镜研究确诊为尤文肉瘤，研究显示细胞内存在糖原颗粒，而细胞学和免疫学分析排除了淋巴系统恶性肿瘤。该病例强调了这些技术在常规光学显微镜检查辅助下，对于明确小圆细胞肿瘤特定诊断的重要性。
