Vulvar leukoplakia includes vulvar leukoplakia, vulvar leukoplakia, or vulvar dystrophy, which was previously thought to be a vascular dystrophy, but with further understanding of the disease, it has not been found to be any of the above alterations, but rather, it is a condition whereby the vulvar skin and mucosal tissues undergo pigmentary changes and degeneration. Because the vulvar skin and mucosa of patients with sclerosing moss and squamous epithelial hyperplasia are often white, they are called vulvar leukoplakia, which is a vulvar intraepithelial non-tumor-like lesion. Sclerosing moss and squamous epithelial cell hyperplasia in different years due to its clinical, pathological understanding of different and several changes in its name, the earliest had been called vulvar leukoplakia, leukoplakia vulvovaginitis, vulvar dryness, proliferative or atrophic vulvovaginitis, neuromuscular dermatitis, sclerosing and atrophic tundra and so on. Because of the confusion over the name of the disease, the International Society for the Study of Vulvar Diseases (ISSVD) referred to them collectively as “chronic vulvar dystrophy” in 1975. In recent years, the understanding of vulvar intraepithelial non-tumor-like lesions has been deepening, and in fact, no clear vascular and neurotrophic disorders have been found in vulvar lesions, therefore, in 1987, the International Society for the Study of Vulvovaginal Diseases (ISSVD) and the International Society of Gynecologic Pathologists (ISGYP) jointly discussed and formulated the new classification of vulvar dermatosis. Because of the outpatient clinic patients, may not have time to explain more than once, write a few patient notes as follows: 1, diet should be light, avoid spicy, seafood, etc., regular life, loose clothing. 2, medication, external drugs such as interferon twice a day, dexamethasone ointment once a night, the Chinese medicine gynecology Shu Ling once a night sitz bath. 3, generally after the use of drugs every half a month to review, if there is a situation at any time to follow-up.
