本文报道９８例中枢神经系统小圆细胞肿瘤电镜诊断资料。常规透射电镜确诊７９例（８０．６％），加免疫组化后确诊１５例（１５．３％），但仍有４例（４．１％）不能确诊。确诊后的肿瘤类型包括胶母细胞瘤、少突胶质细胞瘤、室管膜瘤、髓母细胞瘤、神经母细胞瘤、松果体细胞瘤、原始神经外胚层瘤、恶性淋巴瘤、转移性未分化鳞癌和未分化腺癌、以及黑色素瘤。对上述肿瘤的主要超微结构特征进行了描述，并结合文献阐明了电镜检查对中枢神经系统小圆细胞肿瘤诊断和鉴别诊断有七个方面的作用。
This article reports 98 cases of central nervous system small cell tumor electron microscopy diagnosis data. Conventional transmission electron microscopy confirmed 79 cases (80.6%), plus immunohistochemical diagnosis of 15 cases (15.3%), but still 4 cases (4.1%) can not be confirmed. Tumor types after diagnosis include glioblastoma, oligodendroglioma, ependymoma, medulloblastoma, neuroblastoma, pinealoblastoma, primitive neuroectodermal tumor, malignant lymphoma, metastasis Undifferentiated squamous cell carcinoma and undifferentiated adenocarcinoma, as well as melanoma. The main ultrastructural features of these tumors were described, and combined with the literature elucidated the role of electron microscopy in the diagnosis and differential diagnosis of small cell tumors of the central nervous system in seven aspects.
