Even without treatment, skin abscesses rarely result in death, as they will naturally break through the skin. [3] Other types of abscess are more dangerous. Brain abscesses may be fatal if untreated. When treated, the mortality rate reduces to 5–10%, but is higher if the abscess ruptures. [38]
Skin involvement in subcutaneous tissue infections includes: cutaneous and subcutaneous abscesses, [37] breast abscess, decubitus ulcers, infected pilonidal cyst or sinus, Meleney's ulcer infected diabetic (vascular or trophic) ulcers, bite wound, [38] anaerobic cellulitis and gas gangrene, bacterial synergistic gangrene, and burn wound ...
A skin infection is an infection of the skin in humans and other animals, that can also affect the associated soft tissues such as loose connective tissue and mucous membranes. [ citation needed ] They comprise a category of infections termed skin and skin structure infections (SSSIs), or skin and soft tissue infections (SSTIs), [ 1 ] and acute ...
[4] [needs update] Uncomplicated SSSIs included "simple abscesses, impetiginous lesions, furuncles, and cellulitis." [ 4 ] Complicated SSSIs included "infections either involving deeper soft tissue or requiring significant surgical intervention, such as infected ulcers, burns, and major abscesses or a significant underlying disease state that ...
Pilonidal disease is a type of skin infection which typically occurs as a cyst between the cheeks of the buttocks and often at the upper end. [1] [3] Symptoms may include pain, swelling, and redness. [1] There may also be drainage of fluid, but rarely a fever. [1] [2]
A boil, also called a furuncle, is a deep folliculitis, which is an infection of the hair follicle.It is most commonly caused by infection by the bacterium Staphylococcus aureus, resulting in a painful swollen area on the skin caused by an accumulation of pus and dead tissue. [1]
The wound may be small or it may be an abscess constantly feeding bacteria into the lymphatic system. After infection, lymph nodes enlarge. Ear, skin, nose, and eye infections can spread into the lymphatic system. Red streaks in the skin along the direction of regional lymph nodes indicate lymphatic involvement.
Skin aspiration of nonpurulent cellulitis, usually caused by streptococcal organisms, is rarely helpful for diagnosis, and blood cultures are positive in fewer than 5% of all cases. [16] It is important to evaluate for co-existent abscess, as this finding usually requires surgical drainage as opposed to antibiotic therapy alone.
