作者对31例恶性与非恶性人类喉组织标本进行了光镜与扫描电镜检查结果对比,12例鳞状细胞癌,两种检查结果一致,其余19例中有9例光镜检查疑有恶变,需要再取活检以确诊。对此9例的第一次活检标本作扫描电镜检查,除4例不能肯定外,其余5例中有2例确诊为恶性,3例为非恶性病变,第二次活检结果证实上述结论。在扫描电镜下,非恶性病变的喉粘膜细胞,有许多同方向或螺纹状排列的微型突起(microridge)形成
The author of 31 cases of malignant and non-malignant human laryngeal tissue specimens by light microscopy and scanning electron microscopy results, 12 cases of squamous cell carcinoma, the two test results are consistent, the remaining 19 cases, 9 cases of suspected microscopic examination of malignant transformation, Need to take biopsy to confirm. Of the 9 cases of the first biopsy specimens for scanning electron microscopy, in addition to 4 cases can not be sure, the remaining 5 cases were diagnosed as malignant in 2 cases, 3 cases of non-malignant lesions, the second biopsy confirmed the above conclusion. Under the scanning electron microscope, non-malignant laryngeal mucosal cells, there are many with the same direction or thread-like microridge formation
