Vulvar leukoplakia, clinically known as vulvar dystrophy or vulvar precancer, is a disease caused by cellular lesions, and is commonly referred to as vulvar leukoplakia because more than 80% of patients experience varying degrees of localized skin whitening or whitening of the vulva. Due to the inability of the cells to absorb nutrients from the body, the resistance and recovery of the patient’s body are reduced. Years of the disease lead to various gynecological diseases, such as hardening, roughness, itching, ulceration and cracking of the skin surface, and in severe cases, atrophy or cancer of the vulva may also occur.
