Necrotizing fasciitis (NF) is uncommon and difficult to diagnose, and it cause progressive morbidity until the infectious process is diagnosed and treated medically and surgically. The literature addressed NF contains confusing information, inaccurate bacteriologic data, and antiquated antibiotic therapy.

This review is planned as a guide for the clinician in making an early diagnosis of NF and initiating effective medical and surgical therapy.
