神经鞘肿瘤可以从神经的许旺细胞或从神经束膜细胞发生.前者称之为神经鞘瘤(或许旺细胞瘤),后者称之为神经纤维瘤.以往把两种肿瘤不加区别是不恰当的.有关两种肿瘤的发生部位及组织学结构的差别早有论述.本文仅对一例典型的神经鞘瘤进行电镜观察,结合文献,讨论其超微结构上的特点及与神经纤维瘤的鉴别要点.患者陈某,女,58岁.上腹部包块两年余.在胃小弯处手术切除一卵圆形肿物,约11.5×9×7cm,灰红色,表面光滑,包膜完整.切面实性,灰白色,质硬.光镜观察:有典型的AntoniA和AntoniB两种不同的组织结构.前
Skeletal nerve tumors can occur from the Schwann cells or from the perineurium cells, the former known as schwannoma (or blastocyst), the latter known as neurofibroma. In the past the two tumors without distinction is Inappropriate .Two kinds of tumor occurrence and histological differences have long been discussed.In this paper, only a typical schwannoma observed electron microscopy, combined with the literature to discuss the characteristics of its ultrastructure and neurofibromatosis The identification of the main points of patients Chen, female, aged 58. Upper abdominal mass more than two years in the small curvature of the lesion surgery an oval tumor, about 11.5 × 9 × 7cm, gray-red, smooth surface, capsule Complete. Cut solid, gray, hard. Light microscopy: there are two typical AntoniA and AntoniB organizational structure.
