摘要
本文对44例喉角化症进行临床病理分析,指出喉角化症的发病与过度使用嗓音及大量吸烟有密切关系。分析其病理特点:分为角化伴上皮(典型)增生;角化伴上皮非典型增生;原位癌;癌倾向四种类型。并证明喉角化症癌变的可能性较大。通过对8例正常鳞状上皮、非典型增生上皮和癌上皮的扫描电镜观察,看到上皮表面细胞形状、大小、边缘、细胞间连接等有显著不同。
The raper reports clinical rathologic analysis of 44 cases with the laryngealleukokeratosis. Of them, 8 cases were observed with scanning electronic micro-scope. It was showed that the occurrence of laryngeal keratosis was closelyrelated with over pronunciation and a large consumpation of cigerate and ac-cording to pathological characteristics. Laryngeal keratesis was divided into fo urtypes: keratinization with typical epitheliosis, keratinization with no typicalepitheliosis, preinvasive cancer, infiltrated cancer. The paper proves that canceriza-tion of laryngeal leukokeratosis was quite possible. We observed normal epitheliacells, laryngeal leukokeratosis and cancer cells with scanning electronic microscope.The shape. size, margin and cell connection of surface epithelium cells havesignificant defferentiation.
