Information for Patients


Hidradenitis Suppurativa

Also called: Acne inversa, Suppurative hidradenitis

Hidradenitis suppurativa (HS) is a chronic skin disease. It can occur in one or multiple areas of your body. HS usually develops in your armpits, groin, and anal area. It causes long-term skin inflammation and can be painful.

Symptoms include

  • Blackheads and red, tender bumps, called abscesses. The abscesses get bigger, break open, and leak pus
  • Tunnels that form under the skin between abscesses
  • Scarring

No one knows what causes HS. It is more common in women, African Americans, and people who have had acne. It usually starts after the teenage years. Treatments include antibiotics, anti-inflammatory medicines, and sometimes surgery. Losing weight or wearing looser clothing may help some patients avoid skin irritation.

Hidradenitis suppurativa Hidradenitis suppurativa, also known as acne inversa, is a chronic skin disease characterized by recurrent boil-like lumps (nodules) under the skin. The nodules become inflamed and painful. They tend to break open (rupture), causing abscesses that drain fluid and pus. As the abscesses heal, they produce significant scarring of the skin.The signs and symptoms of hidradenitis suppurativa appear after puberty, usually in a person's teens or twenties. Nodules are most likely to form in the armpits and groin. They may also develop around the anus, on the buttocks, or under the breasts. In some cases, nodules appear in other areas, such as the nape of the neck, waist, and inner thighs.The recurrent nodules and abscesses cause chronic pain and can lead to self-consciousness, social isolation, and depression. Rarely, nodules on the buttocks can develop into a type of skin cancer called squamous cell carcinoma.
