Vulvar white lesions
Introduction
Introduction to white lesions of the vulva The white lesion of the vulva is also called white lesion of the vulva, leukoplakia or vulvar malnutrition. The so-called vulvar leukoplakia actually refers to diseases of tissue degeneration and pigmentation caused by local nerve and vascular dysfunction of the vulva. Clinically, the skin and mucous membranes of the vulva are often whitened and thickened or atrophic diseases, collectively referred to as "vulvar leukoplakia". It is divided into proliferative type, sclerosing moss type and mixed type. basic knowledge The proportion of illness: 0.002% Susceptible people: women Mode of infection: non-infectious Complications: genital itching
Cause
Causes of white lesions of the vulva
Pussy infection and inflammatory irritation (50%)
This is the main cause of leukoplakia, causing many factors of vulvar infection and inflammatory irritation. For example, the usual hygienic habits are not good, the female care solution which is not commonly used in the pH4 weak acid formula is used to clean the vulva, wearing chemical fiber underwear, sanitary products are not clean, bathing in the bath Swimming in the bathing area leads to vaginal inflammation. If it can not be treated in time, the inflammatory secretion infiltrates into the perineum. The long-term infection and stimulation will damage the skin and mucous membranes, causing redness, ulceration and degeneration, which will gradually develop into vulvar leukoplakia.
Endocrine disorders (15%)
Endocrine diseases are caused by endocrine disorders caused by endocrine glands and tissues themselves, or endocrine disorders due to genetic, enzyme defects and immune functions. By measuring the thymine (h3)-labeled thymine, it is believed that there is a protein hormone in the dermis that inhibits epidermal cell division and growth only acts on the epidermis, which is called tissue-specific protein hormone, called statin, which causes local connective tissue hyperplasia and A disorder between the stimulation of epidermal metabolism leads to leukoplakia.
Genetic factors (15%)
The genetically induced vulvar leukoplakia is mainly atrophic, and the patients are mainly young girls. Clinically, patients under the age of 15 should first pay attention to genetic factors, and inquire about the presence or absence of vulvar leukoplakia in their parents' families.
Other factors (10%)
Such as diabetes, vitiligo, vulva eczema, genital itching, etc., such as misuse of drugs, improper treatment, may also lead to or aggravate the formation and development of leukoplakia.
Prevention
Vulvar white lesion prevention
1. Pay attention to menstrual hygiene, and change the menstrual pad during the menstrual period.
2. Keep the vulva clean and dry, do not use hot water to wash, do not scrub with soap.
3. The underwear should be loose, breathable, and suitable for cotton products.
4. Avoid alcohol and spicy food, do not eat seafood and other foods that are extremely susceptible to allergies.
5. Avoid using drugs, abuse drugs, avoid scratching and local friction.
6. If there is damage or infection in the local area, use 1:5000 potassium permanganate solution (add trace potassium permanganate powder in warm water to make it light red, not too thick), dip twice a day. 20-30 minutes each time.
7. Seek medical attention for mold or trichomoniasis. If you have both couples treated at the same time, do not apply "anti-itch water" treatment.
8. Long-term treatment should be done blood sugar check.
Complication
Vulvar white lesion complications Complications, genital itching
Concurrent genital itching and so on.
Symptom
Vulvar white lesion symptoms Common symptoms Sexual intercourse difficulty vulvar itching scaly eczema Diabetes
The genital itching is the main symptom. The itching time is from 2 to 3 months from onset to treatment, and it can be up to 20 years. The severity of itching is not divided into seasons and day and night, such as trichomoniasis or fungal vaginitis. There will be more things, local burning sensation, tingling and itching caused by skin and mucous membrane damage or infection, localized to varying degrees of skin and mucous membrane hypopigmentation, often edema, cleft palate and scattered superficial ulcers.
First, proliferative malnutrition
Generally occurring in women aged 30 to 60 years, the main symptoms are genital itching, the pain is increased after scratching, the range of lesions is different, mainly affecting the labia majora, interlabial space, clitoris foreskin and posterior joint, mostly symmetry The lesions are thickened like leather, with wrinkles in the ridges, or scaly, eczema-like changes, dark red or pink on the surface, white plaques with clear boundaries, and generally no atrophy or adhesion.
Second, hardened mossy malnutrition
Can be seen at any age, more common in women around 40 years old, the main symptoms are itching in the lesion area, but generally far less proliferative lesions, late sexual intercourse difficulties, lesions involving the vulva skin, mucosa and anal skin around the skin, in addition to skin or mucous membranes Whitening, thinning, dry and easy to split, and lose elasticity, the clitoris shrinks more, and adheres to the foreskin, the labia minora disappears flat, the late skin is thin and wrinkled like cigarette paper, the vaginal opening is narrow and narrow, only the fingertips.
Young girls suffering from this disease often feel genital and perianal discomfort after urinating or stool, and there are keyhole-like yellow-yellow plaque-like or white lesions in the vulva and perianal area. Generally, when puberty, the lesions disappear more on their own.
Third, mixed malnutrition
Mainly manifested as the adjacent part of the pubic vaginal leucorrhea, or with focal skin thickening or bulging in its range.
Examine
Examination of white lesions of the vulva
Multi-point biopsy to send pathological examination to determine the nature of the lesion, to rule out early canceration, biopsy should be carried out in the presence of cleft palate, ulcer, bulge, induration or rough, in order to obtain appropriate materials, can be first coated with 1% toluidine blue (toluidine blue) In the lesion area, after whitening, the color is eluted with 1% acetic acid. Any non-decolorizing area indicates that there is a naked nucleus in the area, suggesting that there is a possibility of atypical hyperplasia or even canceration, such as local damage. If the area is too wide, it should be treated for several days. After the skin lesions are mostly healed, the biopsy site is selected to improve the diagnostic accuracy.
Diagnosis
Diagnosis and diagnosis of white lesions of the vulva
diagnosis
If the above symptoms and signs are included, the chronic inflammation caused by diabetes and mold should be ruled out. For further diagnosis, biopsy should be performed. Biopsy should be taken in the presence of cleft palate, ulcer, bulge, induration or rough, or more materials can be taken. To improve the diagnostic accuracy.
Differential diagnosis
It should be differentiated from sclerosing moss, chronic dermatitis, neurodermatitis, leukoplakia, lichen planus, diabetic vulvitis, vulvar papilloma, vitiligo, vulvar cancer, etc., which can whiten vulvar skin.
