摘要
本文对33例光镜诊断为脑转移瘤的病例进行了电镜观察,对两者诊断作了比较。发现电镜观察诊断作了修改或补充的达26例,占79％。归纳起来,电镜观察能起到以下作用:(1)区分脑原发瘤或转移瘤;(2)区分转移瘤的组织类型;(3)为寻找原发瘤提供线索;(4)确定瘤细胞组成中的异质性。以上结果对临床诊断及处理都有一定价值。
33 cases of metastatic tumors of brain werestudied by light and electron microscopy. 26 casesthe original diagnosis made by light microscopywere revised or supplemented after electronmicroscopic examination. The main roles playedby electron microcopy are: (a) distinguishing primarytumors from metastatic tumors; (b) determininghistological type of metastatic tumors; (c) supplyingsome clues for the discovery of the primarytumors; (d) determining the heterogeneity of tumorcells. In addition, we observed the stromal reactionof metastatic tumors including fibrotic andinflammatory reaction.
