We have analyzed, with immunohistochemical staining techniques 26 meningiomas of CNS. Vimentin intermediate filaments was present in all cases in the cytoplasm of tumoral cells. Single epithelium cytokeratin was positive in only 19% cases, same that was obtained with S-100 protein. Whereas 69% of cases expressed epithelial membrane antigen. No case was stained positively with Actin, Desmin and GFAP. The results obtained for others authors are analyzed.
我们采用免疫组织化学染色技术分析了26例中枢神经系统脑膜瘤。波形蛋白中间丝存在于所有病例肿瘤细胞的细胞质中。单克隆上皮细胞角蛋白仅在19%的病例中呈阳性，S-100蛋白检测结果相同。而69%的病例表达上皮膜抗原。没有病例肌动蛋白、结蛋白和胶质纤维酸性蛋白呈阳性染色。对其他作者获得的结果进行了分析。
