Necrotizing fasciitis (NF) is a rapidly progressing soft tissue infection with a mortality rate as high as 30% to 50%. However, the incidence rate of NF after liposuction is extremely low. In the current case report, we describe a woman with NF who developed multiple organ dysfunction syndrome (MODS) after fat acquisition. The aim of this paper is to summarize the management of these patients. After debridement and drainage, correction of multiple organ failure, and plastic surgery, the patient’s organ and lower limb functions improved to a normal level. Early diagnosis, early operative treatment, and correction of systemic abnormalities are the keys to successful recovery of patients with NF complicated with MODS after liposuction.
