It's an infection of the hair follicles of the vulva and/or vaginal lips.
It's generally caused by a bacterial infection, often exacerbated by wearing tight underwear or by hair removal methods that damage the follicle. When the hair cannot emerge properly from the skin, the area becomes inflamed and can become infected by bacteria such as Staphylococcus aureus or fungi. The infection can spread to other follicles and affect a larger area, resulting in a buildup of pus in the genital area, known as a vulvar abscess.
It presents with pain in the genital area, mainly in the pubic region and labia majora. It may be accompanied by redness and warmth of the affected skin. In more severe cases, fever and pus drainage may occur.
Diagnosis is clinical, through questioning of symptoms and examination of the affected area. It may be necessary to perform a general blood test to study the infection.
Treatment includes topical cleansers with antibacterial or antifungal products. In more severe cases, oral antibiotics may be used, and surgical drainage of the abscess may even be necessary.
