Abstract
BACKGROUND
Necrotising fasciitis (NF) is a severe, devastating soft tissue infection characterised by rapidly progressing tissue necrosis. This rare condition has a high mortality rate and poses diagnostic and management challenges to the clinician. There is usually a history of trauma, which maybe trivial. Some of the premorbid conditions associated with NF are diabetes and or immunocompromised state. It requires prompt recognition and early treatment with intravenous antibiotics and extensive surgical debridement.

CASE PRESENTATION
We describe a 74-year-old lady who presented to our emergency department following 3 days’ history of watery diarrhoea and feeling generally unwell. She had signs of severe sepsis and was started on broad-spectrum intravenous antibiotics and fluids for sepsis with unknown source. She was found to have an area of blackish discolouration on her thigh which was suspected as necrotising fasciitis (NF) and referred to the surgeons. She had no history of trauma or significant comorbidity. She underwent surgical exploration and debridement within few hours of arrival into the emergency department and subsequent further debridement with above-knee amputation of the affected limb. She eventually died after about 48 h of hospital stay despite an early diagnosis and prompt surgical debridement and a multidisciplinary approach.

CONCLUSIONS
Necrotising fasciitis has been previously reported in literature but we would like to highlight through this case the importance of looking for the source of sepsis by thorough clinical examination and the need to have a high threshold of suspicion for this rare condition and urgent involvement of a surgical team for debridement.
