Skin and soft-tissue infections
Please click on the specific skin and soft-tissue infections below for further information.
|Anatomic Layers of the Skin||Condition||Definition†||Image|
|Epidermis||Impetigo||Superficial pyogenic infection of the skin which usually begins as vesicles with a very thin, fragile roof consisting only of stratum corneum.|
|Dermis||Erysipelas||Infection of the upper dermis including the superficial lymphatics which typically presents as an indurated, "peau d’orange" lesion with a raised border that is demarcated from uninvolved skin.|
|Folliculitis||Inflammation and/or infection of the hair follicle in which suppuration presents in the epidermis.|
|Infection of the hair follicle in which suppuration extends through the dermis into the subcutaneous tissue. Each lesion consists of a deep-seated inflammatory nodule and an overlying pustule through which hair emerges.|
|Carbuncle||Infection of several adjacent hair follicles, producing a coalescent inflammatory mass with pus draining from multiple follicular orifices.|
|Cellulitis||Acute spreading infection of the deeper dermis and the subcutaneous tissue which lacks sharp demarcation from uninvolved skin.|
|Rapidly progressive infection of deep fascia associated with bullae and necrosis of underlying skin.|
|Rapidly progressive toxemic infection of injured muscle, producing marked edema, crepitus, and brown bullae, characterized by extensive gaseous dissection of muscle and fascial planes on radiography.|

A [[cutaneous abscess]] could occur at multiple locations.
Patients who require hospitalization for ICU admission, operating room surgical intervention, or death have one of the following six risk factors upon presentation:
- abnormal cross-sectional imaging result
- systemic inflammatory response syndrome
- previous infection at the same location
- infection involving the hand
- age >65 years
