Anatomic Layers of the Skin Condition Definition Image
x100% Epidermis Impetigo Superficial pyogenic infection of the skin which usually begins as vesicles with a very thin, fragile roof consisting only of stratum corneum. Impetigo elbow.jpg
x100% 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. Facial erysipelas.jpg
Folliculitis Inflammation and/or infection of the hair follicle in which suppuration presents in the epidermis. Folliculitis.jpg
Furuncle
(Boil)
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. Furuncle.jpg
Carbuncle Infection of several adjacent hair follicles, producing a coalescent inflammatory mass with pus draining from multiple follicular orifices. Carbuncle on buttok.JPG
Cellulitis Acute spreading infection of the deeper dermis and the subcutaneous tissue which lacks sharp demarcation from uninvolved skin. Cellulitis4.jpg
x100% Subcutaneous
Tissue
Necrotizing
Fasciitis
Rapidly progressive infection of deep fascia associated with bullae and necrosis of underlying skin. Necrotizing fasciitis left leg.JPEG
x100% Muscle Myonecrosis
(Gas Gangrene)
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. Gas gangrene.jpg
