鼻咽癌的组织学分类名目繁多,如淋巴上皮癌、移行细胞癌、梭形细胞癌、单纯癌、多形性癌、透明细胞癌、结合细胞癌、基底细胞癌及中间癌等。鼻咽癌有如此多的名称说明根据光学显微镜的检查尚无满意分类。Muir及Shanmugaratnam(1967)观察到正常鼻咽腔的各种上皮——呼吸上皮、鳞状上皮或移行上皮均可在原位恶变。Svoboda等(1967)对三种不同类型的未分化癌进行了电子显微镜研究,发现多数细胞中具有鳞状分化(squanlous different Jation)特征。
There are many histological categories of NPC, such as lymphoid epithelial carcinoma, transitional cell carcinoma, spindle cell carcinoma, simple carcinoma, pleomorphic carcinoma, clear cell carcinoma, combined cell carcinoma, basal cell carcinoma and intermediate carcinoma. There are so many names for nasopharyngeal cancer that there is no satisfactory classification based on light microscopy. Muir and Shanmugaratnam (1967) observed that various epithelial-respiratory, squamous or migratory epithelia in the normal nasopharynx were malignant in situ. Svoboda et al. (1967) studied electron microscopy of three different types of undifferentiated carcinoma and found that most cells have the characteristics of squanlous different Jation.
