Why do acne and pustules appear on the genitals?

Problems can easily occur in women's private parts, which are often called gynecological diseases. Gynecological diseases pose a great threat to women's health, and the appearance of some symptoms affects their normal life. Acne and pustules on the genitals are also accompanied by pain and cannot be touched, making female friends restless. So, why do acne and pustules appear on the genitals? What is the reason?

Furuncle is a purulent infection of hair follicles and the surrounding tissues deep inside the hair follicles. A carbuncle is formed when multiple adjacent hair follicles are infected, inflamed and fused.

Causes

Staphylococcus aureus is the most common pathogen. Recurrent furunculosis in the anogenital area may be secondary to anaerobic infection. 5% are sterile and caused by a foreign body reaction, such as a ruptured cyst. It is more common in teenagers. Susceptibility factors include long-term carriage of S. aureus, diabetes, obesity, poor hygiene habits, and immunodeficiency status.

Clinical manifestations

Initially, small red, swollen and painful nodules appear locally, which gradually swell and become cone-shaped. After a few days, the center of the nodule becomes soft due to tissue necrosis, and small yellow-white pus plugs appear; the area of ​​redness, swelling, and pain expands. After a few more days, the pus plug falls off, the pus is discharged, and the inflammation gradually disappears and heals.

There are generally no obvious systemic symptoms. However, if it occurs in an area rich in blood and the body's resistance is weakened, it can cause symptoms of toxic blood such as discomfort, chills, fever, headache and anorexia. If boils on the face, especially around the upper lip and nose in the so-called "danger triangle", are squeezed or pricked, the infection can easily enter the cavernous sinuses in the skull along the medial angular vein and ophthalmic vein, causing suppurative cavernous sinusitis, with progressive redness, swelling and nodules extending to the eyes and surrounding tissues, accompanied by pain and tenderness, headache, chills, high fever and even coma. The condition is very serious and the mortality rate is very high.

diagnosis

Mainly based on clinical manifestations. Gram stain and culture of the lesions can support the diagnosis. In cases of extensive furuncles and carbuncles, the white blood cell count in the blood increases.

treat

Early inflammatory nodules can be treated with hot compresses or physical therapy (thermal therapy, infrared or ultrashort wave), or with topical antibiotic ointments such as mupirocin ointment. When there is a pus head, apply carbolic acid on the top. When there is fluctuation, drainage should be performed as soon as possible. Immature boils should not be squeezed to avoid spreading the infection.

Antibiotics should be used systemically in the following four situations:

1. Folliculitis is located around the nose, in the nasal cavity or in the external auditory canal.

2. Large or recurrent furunculosis.

3. There is cellulitis around the lesions.

4. The skin lesions do not respond to local treatment.

Drugs that are sensitive to the pathogens, such as penicillin, cephalosporins, macrolides, and clindamycin, should be given.
