Labial dystrophy

The labia is the vulva, an important part of women, and has a very important impact on the health of women's private parts. Of course, the labia itself will also develop certain diseases due to various problems in the human body. For example, vulvar malnutrition is a common problem among women of all ages. Below we will introduce the specific symptoms of vulvar dystrophy in detail.

1. Hyperplastic malnutrition

It usually occurs in women aged 30 to 60. The main symptoms are unbearable itching of the vulva, which is aggravated by scratching. The range of lesions varies, mainly affecting the labia majora, interlabial groove, clitoral hood and posterior commissure. It is mostly symmetrical. The affected skin is thickened like leather, with raised wrinkles, or scales, eczema-like changes, and the surface color is mostly dark red or pink, mixed with clearly defined white patches, generally without atrophy or adhesion.

2. Lichen sclerosus dystrophy

It can be seen at any age, but is more common in women around 40 years old. The main symptom is itching in the lesion area, but it is generally much milder than proliferative lesions. In the late stage, sexual intercourse becomes difficult. The lesions involve the vulvar skin, mucous membranes and skin around the anus. In addition to the skin or mucous membranes turning white, thin, dry and easy to crack, they also lose elasticity. The clitoris often atrophies and adheres to the foreskin. The labia minora flattens and disappears. In the late stage, the skin is thin and wrinkled like cigarette paper, and the vaginal opening is contracted and narrow, only allowing for fingertips.

Young girls who suffer from this disease often feel discomfort in the vulva and perianal area after urinating or defecating, and keyhole-shaped, pearly yellow or white lesions appear in the vulva and perianal area. The lesions usually disappear on their own by the time they reach puberty.

3. Mixed malnutrition

The main manifestations are the areas adjacent to the thin whitish area of ​​the vulva, or accompanied by focal skin thickening or protrusions within its range.

If the above symptoms and signs are present, diabetes and chronic inflammation caused by fungi should also be ruled out. For further diagnosis, a biopsy should be performed. The biopsy should be taken from the areas with cracks, ulcers, protrusions, nodules or roughness. Samples can also be taken from multiple points. To improve the accuracy of diagnosis, the lesion area can be first painted with 1% toluidine blue, and then wiped and decolorized with acetic acid after it dries. Any area that does not decolorize indicates the presence of naked nuclei, indicating that there is a high possibility of finding atypical hyperplasia or cancer in the biopsy at this location. If the lesion area is large, it should be treated for several days first, and then the biopsy can be taken after most of the skin lesions have healed.
