How is vulvar eczema dermatitis diagnosed?

Vulvar eczema is a common disease among women, which usually causes uncomfortable itching in the genitals and sometimes white scales. It is very similar to dermatitis and sometimes misdiagnosis may occur, thus delaying the effect of treatment and causing greater pain. Usually, in the process of diagnosing the disease, the following methods can be used for identification.

Differential diagnosis of vulvar eczema

1. Acute eczema needs to be differentiated from vulvar contact dermatitis.

2. Chronic eczema needs to be differentiated from neurodermatitis vulvar pruritus.

3. Keratotic eczema should be differentiated from psoriasis. Psoriasis has non-exudative lesions with clear borders and is covered with silvery-white scales.

4. Differentiation from female leukoplakia Female leukoplakia is seen in women over 40 years old. The lesions mainly affect the clitoris, labia minora and labia majora mucosa, which are grayish-white spots with hyperkeratosis and severe itching.

5. Differentiate from eczema infection. Eczema infection usually has clear boundaries and circular edges. Small pustular lesions can be seen, showing erythema, exudate and crusting. The crust is yellow and greasy, and there is bright red erosion under the crust. In the folds of the skin, eczema infections often form fissures.

Vulvar eczema prevention measures

Vulvar eczema is more likely to recur. The key is to prevent, find the cause, remove possible pathogenic factors, avoid using drugs and lotions that are irritating to the vulva skin, keep the vulva dry as much as possible, and avoid contact with allergens: such as hot water, scratching, friction and stimulation, etc., fasting spicy food, drinking alcohol, strong tea and coffee, etc.

Local treatment is the main method, and cold wet compresses with saline are used in the acute phase. Apply zinc oxide ointment when erythema, blisters and exudation are not obvious. If there is no exudate or pustules, 1% phenolic glycerin lotion can be used for external washing. If there is obvious exudation, 3% boric acid solution and 1:8000-1:5000 potassium manganate solution can be used for cold wet compress. If erosion occurs, it is advisable to use compound copper sulfate solution for external washing to prevent corrosion and astringency.

In case of secondary bacterial and fungal infection, corresponding antibacterial and antifungal ointments such as 0.5% neomycin ointment, 2% oxytetracycline and zinc oxide ointment can be used for smearing. 0.1% ethacridine (Rivanol) solution can be used for wet compresses. In the scab period, in addition to wet compresses, triamcinolone acetate (triamcinolone) cream, fluocinolone acetonide cream, etc. can be applied to astringe and relieve itching and keep the area dry.

For friends who have vulvar itching, it is best to go to the hospital for examination in time. Once vulvar eczema is found, medication should be carried out in time. The genitals should be kept as clean as possible. The underwear should be loose and breathable to avoid bacterial growth due to long-term moisture, which aggravates the condition.
