File Epidermis Impetigo High contagious superficial skin infection that affects the epidermis. It is classified as bullous and non-bullous, being the latter the most common presentation of impetigo.
  • Bullous: small vesicles that enlarge to a bullae, commonly associated with S. aureus infection.
  • Non-bullous: characteristic "honey-crust" lesions, can be caused by S. aureus or Streptococi.
Ecthyma Severe form of impetigo with ulceration of the pidermis and formation of crust. The legs, thighs and buttocks are the most common affected areas. 2
Dermis Folliculitis Inflammation of a hair follicle.
Furuncle Infection of a hair follicle, also known as boil.
Carbuncle Collection of furuncles with a larger area of involvement and may extend to the subcutaneous tissue.
Erysipelas Superficial skin infection with a clear line of demarcation between involved and uninvolved tissue and raised lesions above the level of the surrounding skin; affects the epidermis and upper dermis.
Cellulitis Diffuse skin infection that involves the deeper dermis and the subcutaneous tissue. It is classified as non-purulent and purulent cellulitis.
  • Non-purulent: with no purulent drainage or exudate and no associated abscess.
  • Purulent: associated with purulent drainage or exudate in the absence of a drainable abscess.
Subcutaneous tissue
Necrotizing fasciitis
Muscle Myonecrosis
