We read the article by Mehta et al.1 with great interest as we were intrigued to hear about a new approach to the management of necrotising fasciitis. However, upon reading it is clear that the authors have made an incorrect diagnosis, which makes the conclusions of their article invalid and may encourage others to pursue a potentially dangerous treatment course. The patient described in the case report has group A Streptococcal toxic shock syndrome, which is very commonly associated with hypotensive episodes, renal failure and necrotic skin,2 and is well known to be treated with antibiotics and systemic support rather than surgery. This falls under the category of necrotising soft tissue infections but, unlike necrotising fasciitis, is limited to the skin. In contrast, necrotising fasciitis causes full thickness tissue death extending down to the fascia, and has little or no response to antibiotic treatment. Whilst the diagnosis is initially a clinical one, confirmation of full thickness tissue necrosis, and turbid ‘‘dishwater’’ fluid in the fascial plane must be made operatively to confirm necrotising fasciitis.3 This fundamental confusion between necrotising fasciitis and other more superficial necrotising soft tissue infections may encourage clinicians unfamiliar
with true necrotising fasciitis to trial medical management, which could result in a fatal delay in surgical intervention. Early involvement of clinicians experienced in the management of complex necrotising soft tissue infections is critical, and prompt surgical exploration remains the gold standard for suspected necrotising fasciitis.
