Chronic Skin Disorder

Hidradenitis suppurativa is a chronic skin disorder affecting the hair follicles. The disease starts with sore red lumps (or boils), typically involving the armpits, breasts, lower abdomen, groin, and buttocks. These lesions appear suddenly, increase in size and then burst or rupture, usually under the surface of the skin. This causes severe pain. Sometimes they rupture to the surface of the skin, draining pus. In some people, they can result in tunnels under the skin that may or may not continue to drain. When the lumps heal, they can leave scars.

Hidradenitis suppurativa is found in about 1% of the population and is more common in women than men. The condition typically begins around puberty, but may also start later.

The cause of hidradenitis suppurativa is unknown. It may be partially caused by genetics since the condition often runs in families. The immune system is over active in people with hidradenitis, which contributes to the inflamed spots or lumps. The disease is not contagious and cannot be passed between people by skin-on-skin touching or touching the drainage from any lesions.

Symptoms, Diagnosis and Outlook

Hidradenitis suppurativa is usually a very painful condition. Some people with the disease will experience draining sores that require daily dressings. Others may also have inflammation and swelling in their joints.

The main symptom of hidradenitis suppurativa is painful, red bumps that occur repeatedly over time. Sometimes the areas itch or have an odor.

There are three stages of hidradenitis suppurativa:

  • Stage 1 includes blackheads and bumps with little scarring
  • Stage 2 includes multiple bumps with a few tunnels and scarring
  • Stage 3 includes multiple bumps and tunnels covering sections of the body, with more extensive tunnels and scarring

Diagnosis of hidradenitis suppurativa can usually be made based on your information about the breakouts and your clinician’s observation of the affected areas.

There is currently no cure for hidradenitis suppurativa. However, treatment can often decrease your symptoms and reduce the condition’s impact on your life.
