[Necrotizing fasciitis caused by group A streptococci].

The number of serious infections from group A streptococci has increased, and there have simultaneously been several cases of necrotizing fasciitis. This is an uncommon, but well-defined entity characterized by extensive necrosis of subcutaneous tissue and fascia, combined with signs of septicaemia. It is often accompanied by multi-organ failure. The mainstay of management is early diagnosis and prompt surgical intervention. It is mandatory that a surgeon, an infectious disease specialist and an anaesthesiologist collaborate on the therapy as a whole.
