The term refers to a bacterial infection of the skin, often manifesting as pustules, crusts, erosions, sometimes deeper ulceration, with redness, pain, and possibly systemic signs (fever, malaise). It can be superficial (impetigo, folliculitis) or deeper (cellulitis, ecthyma) or part of more complex disease (e.g. pyoderma gangrenosum in autoimmune disorders).
