摘要

我们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。所有病例的肿瘤细胞的细胞质中均存在波形蛋白中间丝。单上皮细胞角蛋白阳性仅19%，与S-100蛋白阳性相同。而69%的病例表达上皮膜抗原。未见Actin、Desmin、GFAP阳性。对其他作者的所得结果进行了分析。

[Meningiomas: immunohistochemical analysis of 26 cases].

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.
