Summary of the key points

Necrotising fasciitis is a rare, and potentially fatal subcutaneous infection. Risk factors include diabetes mellitus, peripheral vascular disease, chronic renal failure and immunosuppression.

Streptococcus pyogenes is the most common bacteria isolated. The disease manifests as three main clinical types: A, B and C. These range from a dramatic fulminant presentation to a more subtle and insidious development.

Prompt radical surgical debridement is the definitive management. All patients should receive broad‐spectrum intravenous antibiotics. Intensive care support and meticulous wound care with subsequent reconstruction are key in ensuring a good outcome.
