作者对９例增生型、１０例硬化型、２例混合型外阴营养不良及６例外阴癌进行了电镜观察。结果表明：６例外阴癌均由具有二种或二种以上分化特征的癌细胞组成，认为外阴癌可能起源于具有多潜能分化的鳞状上皮基底细胞。外阴癌的癌细胞间及外阴营养不良的上皮细胞间均可见淋巴细胞浸润，并对癌细胞及上皮细胞质膜有不同程度的破坏，淋巴细胞对癌细胞的破坏作用系机体的保护机理，而外阴营养不良上皮间淋巴细胞出现的意义还有待进一步研究。
The authors observed 9 cases of hyperplastic, 10 cases of sclerosis, 2 cases of mixed vulvar dystrophy and 6 cases of vulvar cancer were observed by electron microscopy. The results showed that all 6 cases of vulvar cancer were composed of cancer cells with two or more differentiated features, suggesting that vulvar cancer may originate from multipotent squamous cell differentiation basal cells. Vulva cancer cells and vulvar dysplasia of epithelial cells were seen in lymphocytes infiltration, and cancer cells and epithelial plasma membrane damage in varying degrees, the destruction of lymphocytes on the role of cancer cells, the body’s protective mechanism, and the vulva Malnutrition, the significance of epithelial lymphocytes remains to be further studied.
