Hidradenitis suppurativa (HS)
is an inflammatory condition of the hair follicle. Recurrent, inflamed nodules and cysts
form in the armpits and groin. These may also be found under the breasts, and around the nipples and anus. Less commonly other areas of the body can be affected.

The hair follicle becomes blocked causing inflammation. The blockage may lead to absesses, infection, or scarring. The sweat glands may also become inflammed.
Menstruation in women, weight gain, stress, hormonal changes, heat, and excesive perspiration may trigger the condition.
HS is more common in women than in men. Other factors that increase your chance of HS include:
- Family history
Current or history of smoking
Metabolic syndrome—a condition marked by elevated blood pressure, cholesterol, blood glucose, and body weight
Lipid disorders, including low HDL (good) cholesterol levels and/or high triglycerides
HS usually presents at puberty, but may occiur at any age after that. It may cause:
- Burning, itching, or painful lumps in the armpits, groin, under the breasts, around the nipples or anus, and other involved areas
- Pus leaking from openings in the lumps
There are 3 stages of the condition:
- Harley stage 1: single or multiple abscesses without sinus tracts or scarring
- Harley stage 2: recurrent single abscesses or multiple widely separated lesions with sinustract formation and scarring
- Harley stage 3: multiple interconnected tracts and abscesses are observed across the entire area with diffuse or near-diffuse involvement
You will be asked about your symptoms and medical history. A physical exam will be done.
In most cases, the doctor will be able to make a diagnosis by looking at the abscesses and nodules.
Sometimes cultures will be done of drainage. Occasionally other blood tests or ultrasond of the lesions is done.
The treatment with depend on the stage of the disease. Talk with your doctor about the best treatment plan for you. Options may include one or more of the following:
Home Care and Lifestyle Changes
You may be able to improve the condition by taking these steps:
- Use warm compresses to relieve discomfort and promote abscess drainage.
- Avoid shaving if your skin becomes irritated.
- Wear loose-fitting, nonsynthetic clothing.
- Use antibacterial soap.
- Try to avoid heat and humidity.
If you smoke, talk to your doctor about finding a program to help you
quit. It is also important to maintain a
and eat a healthful diet. If you need help losing weight, consider talking to a dietitian who can help you with meal planning.
Your doctor may prescribe one or more medications depending on the severity of your HS.
Your doctor may recommend oral or topical antibiotics.
Corticosteroids and Other Immunosuppresants
Corticosteroids may help improve symptoms. These can be taken by mouth, applied to the skin, or injected into the area.
Other medications called biologics, which decrease the bodies immune response, may be used in severe cases. These medications have many risks, so your doctor will carefully weigh the risks and benefits of using these.
Hormonal medications, such as oral contraceptives can be used in some cases. At other times, medications called retinoids may be used.
Small lesions can be treated in the doctor's office.
The sores may be cut open and allowed to drain. If your condition is severe, then a wide area may need to be removed. In these cases, a
may be needed.
Other procedure options include:
- Laser surgery—uses lasers to remove
- Cryosurgery—uses cold to freeze lesions
- Laser hair removal
There are no current guidelines to prevent HS.
