Causes of vulvar and perianal itching

I believe everyone is familiar with the disease of vulvar and perianal pruritus. Vulvar and perianal pruritus is a common gynecological disease. Although vulvar and perianal pruritus will not threaten the patient's life, the occurrence of vulvar and perianal pruritus can easily bring discomfort to female friends. Therefore, we recommend that female friends pay attention to this disease. In the following article, we will tell you the causes of vulvar and perianal pruritus.

1. Vaginal trichomoniasis: Itching of the vulva and vagina, foamy leucorrhea, often accompanied by a special odor, and eczematous changes in the vulva after scratching. A vaginal smear test can be used to distinguish it from the above conditions.

2. Fungal vaginitis: itching of the vulva and vagina, flushing of the vulva, dregs-like leucorrhea with an odor. Scratching may cause eczematous changes of the vulvar dermatitis.

3. Local skin uncleanness: Some women use toilet paper improperly, and the skin of the vulva is soaked by menstrual blood, vaginal secretions, and even urine, feces and sweat, which causes chronic inflammation of the local skin and causes vulva itching.

4. Drug allergy: Women with allergic constitutions may suffer from "fixed drug rash" caused by taking sulfonamides or other drugs. This rash often occurs at the junction of the skin and mucous membrane of the vulva. In addition to local itching, it may also be complicated by erosion and exudation. Vulvar itching may also occur if allergic reactions and contact dermatitis occur when using drugs for vaginal washing or vaginal insertion.

5. Skin diseases of the vulva: The skin lesions of tinea cruris often extend to the vulva, causing severe local itching. The local itching caused by vulvar eczema and neurodermatitis is more severe. The former is manifested as papules and blisters with unclear local skin boundaries and erosion exudate, while the latter often causes thickening of the skin with lichenification due to scratching. In addition to causing local itching, leukoplakia of the vulva is often accompanied by vulvar malnutrition and skin atrophy.

6. Viral infection: Genital warts mostly occur in the female vaginal wall, cervix and vulva, and may also cause foul-smelling leucorrhea. Molluscum contagiosum occurring in the vulva often presents as round papules with an umbilical-like depression in the center, and may also cause itching in the vulva. Genital herpes is often manifested by the appearance of bright, rice-sized blisters on the urethral opening and vaginal wall, accompanied by local itching.

7. Sexual allergy: This is an allergic reaction that occurs during sexual intercourse. There are people who are allergic to semen, condoms, and friction.
