Necrotizing fasciitis in infancy: an uncommon setting and a prognostic disadvantage.

Necrotizing fasciitis is a potentially fatal, progressive soft tissue infection that typically occurs in adults, and only rarely occurs in infants. Although adults in whom necrotizing fasciitis develops are commonly diabetic, malnourished, or otherwise immunocompromised, infants in whom the disease develops are typically healthy and without clear predisposing factors. Herein, however, the authors report the case of an infant with compromised immunity secondary to the manifestations and treatment of panhypopituitarism, in whom postoperative necrotizing fasciitis developed after bilateral inguinal herniorrhaphy. The diagnosis, pathological mechanism, and treatment of necrotizing fasciitis are reviewed and the distinguishing features in infants are highlighted. The combination of a low incidence and very high mortality rate associated with necrotizing fasciitis in this subgroup strengthens the need for hypercritical suspicion. Early diagnosis and the prompt initiation of surgical treatment are the most essential means to improve on the prognosis for necrotizing fasciitis in infants.
