Impetigo

Definitions of Skin/Soft Tissue Infections

  • Cellulitis (see Cellulitis, [[Cellulitis]]): skin infection of deeper dermis and subcutaneous fat (resulting from bacterial breach of the skin) characterized by erythema, warmth, and edema without an underlying suppurative focus
  • Erysipelas (see Erysipelas, [[Erysipelas]]): skin infection of upper dermis and superficial lymphatics (resulting from bacterial breach of the skin) characterized by erythema, warmth, and edema without an underlying suppurative focus
  • Impetigo: infection of superficial layers of the epidermis
  • Necrotizing Soft Tissue Infection (see Necrotizing Soft Tissue Infection, [[Necrotizing Soft Tissue Infection]]): all of these are characterized by fulminant tissue destruction, systemic toxicity, and high mortality rates
    • Necrotizing Cellulitis
      • Meleney’s Synergistic Gangrene
      • Clostridial Anaerobic Necrotizing Cellulitis
      • Non-Clostridial Anaerobic Necrotizing Cellulitis
    • Necrotizing Fasciitis: deep-seated infection of subcutaneous tissue (involving fascia and fat), which may spare the skin
      • Type I (Mixed Aerobic and Anaerobic Infection)
      • Type II (Monomicrobial Infection)
    • Necrotizing Myositis (Spontaneous Gangrenous Myositis)
  • Clostridial Myonecrosis (Gas Gangrene) (see Clostridial Myonecrosis, [[Clostridial Myonecrosis]]): life-threatening muscle infection which develops either contiguously from a site of trauma or via hematogenous spread from the gastrointestinal tract to the muscle
  • Furuncle (Boil) (see Skin Abscess, [[Skin Abscess]]): infection of hair follicle where purulent material extends through the dermis into the subcutaneous tissue, forming a small abscess
  • Carbuncle (see Skin Abscess, [[Skin Abscess]]): coalescence of several inflamed follicles into a single inflammatory mass with purulent drainage from multiple follicles
  • Skin Abscess (see Skin Abscess, [[Skin Abscess]]): collection of pus within dermis and deeper skin tissues
