Women with pruritus vulvae and papules often have itching sensation in vagina, outside labia majora, pubic mound, clitoris, labia minora and perineum, which can spread to the vicinity of anus. This is a local itching. Itching is often unbearable, especially at night. If the vulva pimple grows on the labia majora, it may be caused by local infection. If it grows under the labia minora, it may be a papillary cyst. There are usually these reasons that cause female vulvar pruritus accompanied by papules: 1, bad hygiene habits: not paying attention to local cleaning of vulva, long-term stimulation of sebum, sweat, menstrual blood and vaginal secretions, or soaking in urine and feces can all cause vulvar pruritus. Menstrual sanitary napkins, usually wearing airtight chemical fiber underwear, will cause itching, redness and pimples of vulva due to local long-term damp and heat stagnation. 2. Many women are willing to wear some tight underwear, which leads to sweating, bacterial growth, itching, redness and pimples in the vulva. 3, special infection: Candida vaginitis and trichomonal vaginitis are the most common causes of vulvar itching. Crabs and scabies can also cause vulvar itching, redness and papules. 4, vulvar squamous epithelial cell hyperplasia: itching as the main symptom, accompanied by vulvar skin whitening. 5. Drug allergy or chemical stimulation: soap, condoms, benzalkonium bromide, etc. Contact or allergic dermatitis may be caused by direct stimulation or allergy, resulting in pruritus, redness and pimples of vulva. 6. Other skin lesions: abrasions, warts, herpes, tumors, etc. Can cause pruritus, redness, and small papules of vulva.
