Necrotizing soft tissue infections (STIs) are serious complications that may arise from pressure ulcers. However, there are few studies on this important issue. In addition, diagnostic criteria for necrotizing STIs developing from pressure ulcers and infected pressure ulcers are not well established. ⋯ Necrotizing STIs arising from pressure ulcers are generally caused by mixed pathogens and exhibit symptoms that are milder than those of necrotizing fasciitis caused by group A Streptococcus.
