This case report details the progress of a patient with severe disseminated gonococcal infection with associated necrotising fasciitis. His admission was punctuated by multiple surgical debridements and a prolonged intensive care stay due to multiple organ failure. An extended course of azithromycin-based antimicrobial therapy achieved a cure and the patient was eventually discharged home after 8 weeks. To our knowledge this is the first such case of histologically and microbiologically confirmed gonococcal necrotising fasciitis.
