ABSCESSES

Skin abscesses are fairly common. They affect people of all ages. They are caused when an infection causes pus and infected material to collect in the skin. The infection may spread locally or throughout the body.

What are Abscesses?

A localized collection of pus in any part of the body that is the result of an infection. Abscesses can form in almost every part of the body.

Abscesses occur when an area of tissue becomes infected and the body is able to "wall off" the infection and keep it from spreading. White blood cells, the body's defense against some types of infection, migrate through the walls of the blood vessels into the area of the infection and collect within the damaged tissue. During this process "pus" forms which is an accumulation of fluid, living and dead white blood cells, dead (necrotic) tissue, and bacteria or other foreign invaders or materials.

Skin abscesses may follow a bacterial infection, commonly an infection with staphylococcus. They can develop after a minor wound, injury, or as a complication of folliculitis or boils. The abscess can prevent deeper tissues from functioning properly. The infection may spread locally or throughout the body. The spread of infection through the bloodstream may cause severe complications.

How are Abscesses Diagnosed?

Often, a sample of fluid will be obtained from the abscess. It will be cultured to determine the organism causing the abscess.

How are Abscesses Treated?

Treatment varies, but often requires antibiotics. See the individual types of abscesses.
