Hidradenitis suppurativa (chronic collections of pus)

Description Inflammation, swell...

Description

Inflammation, swelling and infection of the armpit, groin, buttocks or under the breast. Tender bumps develop and can turn into a collection of pus (abscess). The area is painful, warm to touch and can drain foul smelling yellow fluid. The inflammation begins after the sweat glands in the affected area become clogged allowing bacteria to infect the skin and sweat glands. Hydradenitis suppurativa usually begins after puberty and can be recurrent. If the condition is not treated chronic scarring and a surrounding skin infection can occur called cellulitis. Sometimes cellulitis can be life threatening.

Symptoms

Redness and swelling of the affected area. The skin is warm to touch and can feel hard. The area is very tender and can restrict movement. Small red bumps and black heads can be seen as well. Foul smelling yellow fluid can leak from the swollen areas.

Tests

Treatment

Very mild cases can be treated with warm compresses. Most cases require oral antibiotics. If a surrounding skin infection has occurred (cellulitis) intravenous antibiotics may be needed. If an abscess has developed the area may need to be opened and drained. If the same area becomes involved multiple times a surgeon may need to remove the damaged skin and sweat glands.
