近十年来 ,鼻咽癌病理学诊断研究取得了较大的进展。现将其中较新颖和实用的内容介绍如下。1　鼻咽的解剖组织学按国际抗癌联盟 ( UICC)规定 ,鼻咽壁分为顶后壁、两侧壁和下 (前 )壁四部分。多数早期鼻咽癌发生在侧壁咽隐窝 ,而不是以前认为的顶后壁。后鼻孔开口与鼻中隔后缘是 In the past decade, the pathological diagnosis of nasopharyngeal carcinoma has made great progress. Here are some of the more innovative and practical contents as follows. 1 Anatomical histology of the nasopharyngeal According to the provisions of the International Union Against Cancer (UICC), the nasopharyngeal wall is divided into four parts: the posterior wall, the two lateral walls, and the inferior (anterior) wall. Most of the early nasopharyngeal carcinomas occurred in the lateral pharyngeal crypts rather than the apical posterior wall previously thought. The opening of the posterior nostril and the posterior border of the septum are
