Boils on the vulva. The first and most common cause of boils is due to folliculitis of the vulva, which leads to blockage of hair follicles and thus boils, and is treated mainly with topical antibiotic applications. Secondly, it is caused by an infection of the skin of the vulva. Again, it is a local allergic reaction due to mosquito bites, usually accompanied by local itching and a clear history of mosquito bites. It is caused by skin diseases of the vulva, such as sclerosing moss of the vulvar skin, hyperplasia of the vulvar lenticular epithelium, and, more rarely, malignant and benign tumors of the vulva. Finally, boils on the vulva may occur due to sexually transmitted diseases, usually due to a history of impure sexual intercourse. Treatment depends on the specific condition, but you need to pay attention to local hygiene, pay attention to sexual hygiene, and avoid sexual promiscuity.
