Hidradenitis Suppurativa
Introduction
Hidradenitis suppurativa is a chronic skin inflammation marked by the presence of blackheads and one or more red, tender bumps (lesions). The lesions often enlarge, break open and drain pus. Scarring may result after several occurrences.
The cause of hidradenitis suppurativa isn't known. But it's considered a severe form of acne (acne inversa) because it occurs deep in the skin around oil (sebaceous) glands and hair follicles. The parts of the body affected — the groin and armpits, for example — are also the main locations of apocrine sweat glands.
Hidradenitis suppurativa tends to start after puberty, persist for years and worsen over time. There is no cure for hidradenitis suppurativa. But early diagnosis and treatment can help manage the symptoms and prevent new lesions from developing.
Signs And Symptoms
Hidradenitis suppurativa commonly occurs around hair follicles where many oil and sweat glands are found, such as the armpits, groin and anal area. It may also occur in areas where skin rubs together, such as the inner thighs, under the breasts or between the buttocks. Hidradenitis suppurativa can affect a single area or multiple areas of the body.
Signs and symptoms of hidradenitis suppurativa include:
- Small pitted areas of skin containing blackheads, often appearing in pairs or a "double-barrel" pattern.
- One or more red, tender bumps (lesions) that fill with pus. The bumps often enlarge, break open and drain pus. The drainage may have an unpleasant odor. Itching, burning and excessive sweating may accompany the bumps.
- Painful, pea-sized lumps that grow under the skin. These hard lumps, which may persist for years, can enlarge and become inflamed.
- Painful bumps or sores that continually leak fluid. These open wounds heal very slowly, if at all, often leading to scarring and the development of tunnels under the skin.
Causes
Hidradenitis suppurativa develops when the oil glands and hair follicle openings become blocked. When oils and other skin products become trapped, they push into surrounding tissue. Bacteria can then trigger infection and inflammation. It's not known why this occurs, but a number of factors — including hormones, genetics, cigarette smoking and excess weight — may all play a role.
Sometimes hidradenitis suppurativa occurs with other diseases, such as Crohn's disease, herpes simplex or Grave's disease.
Treatment
There is no cure for hidradenitis suppurativa. But early treatment can help manage the symptoms and prevent new lesions from developing.
Treatments depend on the extent of the affected areas and whether the sores are painful or infected. Mild cases can be treated with self-care measures, including warm compresses and regular washings with antibacterial soap. Moderate cases may require medications, such as those you rub on the affected areas (topical medications) or those you take by mouth (oral medications). Possible medications include:
- Antibiotics to treat infection. Antibiotics taken for a long time early in the disease may prevent future outbreaks or prevent the disease from worsening.
- Oral retinoid medications to stop oil gland functions and to prevent the plugging of the hair follicle.
- Nonsteroidal anti-inflammatory drugs to reduce pain and swelling.
- Corticosteroids or immunosuppressant drugs.
- Incision and drainage. Surgical drainage or removal of the lesions may be an option when the disease involves a single small area. However, this treatment won't prevent the disease from returning and is generally used for short-term relief.
- Uncovering the tunnels or tracts. Cutting away skin and flesh that cover any tunnels or tracts can increase healing of the lesions and minimize scarring. This doesn't prevent the disease from returning in the treated area or another area of the body, however.
- Surgical removal. Surgical treatment of recurrent or severe symptoms involves removal of all involved skin followed by direct closure with skin flaps or with skin grafting (removing skin from one area of your body and attaching it to another). Full surgical removal of the affected areas can treat the disease that is present but doesn't prevent the disease from occurring in other areas.
