| Definition: | Skin abscess is a collection of pus and infected material in or on the skin.
|
| Alternative Names: | Abscess - skin; Cutaneous abscess; Subcutaneous abscess
|
| Causes, incidence, and risk factors: | Skin abscesses are fairly common. They are caused when a localized infection causes pus and infected material to collect in the skin or subcutaneous tissue. Skin abscesses may follow a bacterial infection, commonly an infection with staphylococcus (staph aureus is most common). They can develop after a minor wound, injury, or as a complication of folliculitis or boils (furuncles, carbuncles). Skin abscesses may occur anywhere on the body. They affect people of all ages.
The abscess can obstruct and impinge on the functioning of deeper tissues. The infection may spread locally or systemically. The spread of infection through the bloodstream may cause severe complications.
