摘要

本文报告一例23周龄胎儿的先天性室管膜瘤。肿瘤血管丰富,包含典型的室管膜玫瑰花结。肿瘤细胞与gfap -抗血清无反应。它们与神经元特异性烯醇化酶和波形蛋白反应弱,与s -100蛋白抗血清表现出较强的抗原性。从一些肿瘤细胞中可记录到细胞角蛋白抗原。肿瘤足够成熟,可归类为室管膜瘤。免疫组化结果提示肿瘤细胞可能起源于外胚层。

[Congenital ependymoma. Case report and immunohistochemical studies].

Reported in this paper is a congenital ependymoma in an 23-week old foetus. The neoplasm was well vascularised and contained typical ependymal rosettes. The tumour cells did not react with GFAP-antiserum. They reacted weakly with neuron-specific enolase and vimentin and exhibited strong antigenicity with S-100-protein-antiserum. Cytokeratin antigen was recordable from some tumour cells. The tumour was sufficiently mature for classification as ependymoma. Immunohistochemical findings suggested possible ectodermal origin of the tumour cells.
