Hidradenitis suppurativa is a cyst of the sacrococcygeal intergluteal fissure skin, which is often incised and drained when symptoms are evident, and recurrences can be treated by surgical excision and can be completely cured. Hidradenitis suppurativa cysts are usually small holes or cavities located above or near the gluteal crease, where hair or clothing friction causes localized skin depressions and hair penetration into the skin. The initial stage is often asymptomatic, but patients are infected with localized redness, pain and swelling, and even pus and oozing. After perfecting ultrasound, pelvic magnetic resonance and other related examinations, patients should be treated with surgical incision and drainage or surgical excision according to the severity of the condition, and antibiotics such as cephalosporin or amoxicillin should be selected for anti-infection treatment if necessary. Patients should use medication under the guidance of the doctor, avoid self-medication and delay the condition.
