A Rare Cause of Necrotizing Fasciitis: Psoas Abscess

Necrotizing fasciitis always carries very high mortality and morbidity rates. It can be due to group A beta-haemolytic streptococci, which are traditionally described as the flesh-eating bacteria. More commonly, it is related to a mixed growth of bacteria that can be secondary to trauma or surgery. Secondary necrotizing fasciitis due to concomitant soft tissue infection is uncommon. We reported a fatal case of necrotizing fasciitis which was caused by a coexisting psoas abscess. A search for concomitant soft tissue infection is warranted in patients presenting with necrotizing fasciitis. This article also reviewed the clinical tools that may help to make an early diagnosis of the disease.
