Perineal abscess may be caused by vulvar folliculitis and vestibulitis, which usually require surgical treatment. 1. Vulvar folliculitis: this disease is mainly caused by bacterial infection, which starts as a pimple and can develop into a pimple-like pustule or even a boil, causing a perineal abscess. If the abscess is large or a boil is formed, surgical incision and drainage is needed to drain the pus. 2. Vestibular adenitis: this disease is caused by bacterial infection, which will lead to edema and obstruction of the opening of the gland duct, and the secretion can not be discharged in time to form a vestibular adenoid abscess, causing perineal abscess, with severe pain, and a fluctuating sensation can be touched locally. Surgical incision and drainage are needed as soon as possible, and drainage strips are placed. If the complication of vestibular gland cyst, the cyst is large, feasible cystostomy. It is recommended to consult the doctor for timely treatment, and can usually be cured after active treatment.
