鼻咽部上皮组织类型较多,有假复层纤毛柱状上皮,复层鳞形上皮及介于二者之间的移行上皮;在固有层中尚有腺组织。这些上皮组织细胞癌变后,形成的癌细胞类型也多。因而增加了鼻咽癌病理分型的复杂性。虽然不少学者在研究鼻咽癌微细结构的同时,也对鼻咽部上皮组织作了电镜观察,但目前文献中仅有鼻咽部上皮组织的组织学资料,未查到专门的电镜观察资料。为了研究鼻咽癌的微细结构及鼻咽癌微细结构与病理分型的关系,我们对鼻咽部上皮组织(包括腺组织)作了电镜观察,以便借鉴于鼻咽部正常上皮细胞微细结构的特点,来判断癌细胞的来源及分化程度。
Nasopharyngeal epithelial tissue types are more, with pseudostratified ciliated columnar epithelium, stratified squamous epithelium and between the transitional epithelium between the two; there are still in the lamina propria glandular tissue. After these epithelial cells have become cancerous, many types of cancer cells are formed. Thus increasing the complexity of the pathological type of NPC. Although many scholars in the study of the fine structure of nasopharyngeal carcinoma, but also on the nasopharyngeal epithelial tissue made by electron microscopy, but the current literature only the histological data of nasopharyngeal epithelial tissue, did not find a special electron microscopy observations . In order to study the microstructure of nasopharyngeal carcinoma and the relationship between the microstructure of nasopharyngeal carcinoma and the pathological classification of nasopharyngeal carcinoma, we examined the epithelial tissues of the nasopharyngeal tissues (including glandular tissue) by electron microscopy in order to learn from the normal structure of nasopharyngeal epithelial cells Characteristics, to determine the source of cancer cells and the degree of differentiation.
