Alternative namesAbscess - skin; Cutaneous abscess; Subcutaneous abscess
DefinitionA skin abscess is a collection of pus and infected material in or on the skin.
Causes, incidence, and risk factors
Skin abscesses are fairly common. They are caused when an infection causes pus and infected material to collect in the skin. 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 . Skin abscesses may occur anywhere on the body. They affect people of all ages.
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.
Signs and testsYour doctor can diagnose the condition based on the appearance of the area. A culture or examination of any drainage from the lesion may help identify what organism is causing it.
The goal of treatment is to cure the infection. The doctor may cut and drain the abscess to clean the area and control the infection. Antibiotics such as dicloxacillin are given to control the infection.
Heat (such as warm compresses) may speed healing, reduce inflammation, and make the area feel better. Elevate the affected part to reduce swelling and inflammation.
Expectations (prognosis)Most skin abscesses can be cured with proper treatment.
Calling your health care providerCall for an appointment with your health care provider if any signs of skin infection occur -- including fever, pain, redness, swelling, or drainage of any kind.
Also call for an appointment with your health care provider if new symptoms develop during or after treatment of a skin abscess.
PreventionPrevent and watch for bacterial infections. Keep the skin around minor wounds clean and dry. Consult the health care provider if you develop signs of infection. Treat minor infections promptly.
