女阴癌是常见的一种妇科恶性肿瘤,虽然女阴癌比宫颈癌、子宫内膜癌、卵巢癌等少见得多,但是由于它症状不典型,无特异型,患者和医务人员又常忽视已出现的症状和体征,往往耽误诊断和治疗,以致影响妇女的健康和生命。为此要做到女阴癌的早期发现、早期诊断和早期治疗,必须强调要重视女阴癌前病变。女阴癌前病变是指女阴上皮非典型增生。与宫颈上皮内瘤样病变一样,女阴也有女阴上皮内瘤样病变(vulvar intraepithelial neoplasia,VIN),这是一组女阴疾病,多见于绝经后妇女,但近年来年轻妇女患病者逐渐增多。根据细胞非典型增生的不同程度,VIN 可分为三级:即VIN Ⅰ级指女阴非典型增生Ⅰ级,VINⅡ级为女阴非典型增生Ⅱ级,VINⅢ级指女阴非典型增生Ⅲ级及原位癌。女阴非典型增生和宫颈非典型增生一样,可以自然消失,也可发展为原位癌或浸润癌,然而其发展不如宫颈癌那样明显。妇女患女阴非典型增生之前常有女阴营养障碍或称女阴白色病变等病史。女阴白色病变是常见的女阴良性病变,是由于不同的刺激使女阴产生萎缩性或增生性变化,导致局部或广泛的色素减退,形成白色病
Female cancer is a common gynecological cancer, although female cancer is more rare than cervical cancer, endometrial cancer, ovarian cancer, but because of its atypical symptoms, non-specific, patients and medical staff often overlooked The symptoms and signs that have appeared are often delayed diagnosis and treatment, affecting women’s health and life. To do this to find the early detection of female cancer, early diagnosis and early treatment, must emphasize the importance of female precancerous lesions. Female precancerous lesions refer to the atypical hyperplasia of the vulva. Vulvar intraepithelial neoplasia (VIN), like that of cervical intraepithelial neoplasia, is a group of women’s diseases of the vulva that are more common in postmenopausal women, but the number of young women in recent years has gradually decreased increase. According to the different degree of cell atypical hyperplasia, VIN can be divided into three levels: the VIN Ⅰ level refers to the atypical hyperplasia of the female genital grade Ⅰ, VIN Ⅱ grade female atypia hyperplasia grade Ⅱ, VIN Ⅲ grade refers to the female atypia hyperplasia grade Ⅲ And carcinoma in situ. Atypical hyperplasia and cervical dysplasia, like cervical, can disappear naturally, but also the development of carcinoma in situ or invasive cancer, but its development is not as obvious as cervical cancer. Women suffering from atypical hyperplasia of female vaginitis often female dystrophy or female vaginitis and other medical history. Female vaginal lesion is a common female Yin benign lesions is due to different stimuli female vaginal produce atrophy or proliferative changes, leading to local or widespread hypopigmentation, the formation of white disease
