What is the disease that causes vulvar itching and whitening?

If a woman's genitals are not well cared for, a series of problems will arise, which will not only affect her physical health, but also affect the normal sexual life of the couple. For example, some women, in addition to symptoms of vulvar itching, may also have white spots on the vulva, and sometimes even feel a tingling sensation in the vulva. So, what is the disease of vulvar itching and whitening?

Vulvar leukoplakia is also called chronic vulvar dystrophy or vulvar leukoplakia. The so-called vulvar leukoplakia actually refers to a disease of tissue degeneration and pigment changes caused by local nerve and vascular nutrition disorders in the vulva. Clinically, diseases in which the skin and mucous membranes of the vulva become white, coarse, or atrophic are collectively referred to as "vulvar leukoplakia." There are many factors that cause vulvar infection and inflammatory irritation, such as poor hygiene habits, not often using pH 4 weak acid formula feminine care solution to clean the vulva, wearing synthetic underwear, unclean sanitary products, bathing in a bathhouse, swimming in a bathhouse, etc., which lead to vaginal inflammation. If it is not treated in time, the inflammatory secretions will infiltrate the perineum, and long-term infection and irritation will damage the skin and mucous membranes, causing redness, swelling, ulcers and degeneration, which will gradually develop into vulvar leukoplakia.

Those who show atypical cell hyperplasia in clinical pathological examination fall into the category of "vulvar itch", "vulvar pain" and "vulvar pain" in traditional Chinese medicine, which is mostly caused by damp heat in the liver meridian invading the vulva, or blood deficiency and liver hyperactivity, liver-kidney yin deficiency, kidney yang deficiency, etc., which are unable to nourish the vulva due to essence and blood. Vulvar itching, sometimes with burning and pain. Vulvar leukoplakia, also known as vulvar white lesions, is a chronic female vulvar malnutrition disease. It includes primary vulvar atrophy, atrophic lichen sclerosus, vulvar leukoplakia, leukoplakia vaginitis, and vulvar dryness. Clinicians usually refer to vulvar diseases in which the skin and mucous tissue become white, coarse, and atrophic as vulvar leukoplakia.

In traditional Chinese medicine, this disease is called Yin moss, Yin sore, Yin erosion, and Yin pain. It is a precancerous lesion. Benign keratotic lesions in the vulva are called white keratosis. White keratosis that does not heal for a long time may further develop into vulvar leukoplakia. The cause of the disease is unclear, but it may be related to systemic factors, such as diabetes and endocrine disorders. The local environment of the vulva, such as moisture, heat and other physical stimulation, can induce vulvar leukoplakia. Histopathology shows proliferative lesions of the mucosal epithelium or epidermis. Under normal circumstances, the vulvar mucosa has no granular layer and stratum corneum. If white keratosis or vulvar leukoplakia occurs, the granular layer will be thickened. If it occurs in the transitional area of ​​the skin and mucosa of the labia majora, there will be obvious hyperkeratosis, thickening of the granular layer, and hypertrophy of the spinous layer. About 80% of the lesions are benign white keratosis, and there is no acanthocyte atypia in the spinous cell layer, and generally no dyskeratinized cells. Under the epidermis is chronic inflammatory cell infiltration. In vulvar leukoplakia, early metamorphosis can be seen, that is, some spinous cells appear amorphous, the nuclear size is inconsistent, the cell size is also inconsistent, the spinous cells are arranged disorderly, there are dyskeratotic cells in the superficial layer of spinous cells, called malignant dyskeratotic cells, there are varying degrees of inflammatory cell infiltration in the dermis, and there is no pure degeneration of collagen fibers in the superficial dermis.
