Necrotizing Fasciitis in Hematological Patients: Enterobacteriaceae Predominance and Limited Utility of Laboratory Risk Indicator for Necrotizing Fasciitis Score.

Immune suppression is a recognized risk factor for necrotizing fasciitis. In patients with hematological malignancies, a profoundly immunocompromised group, the predominant causative organisms are Gram negative. Clinical presentation and outcomes in these patients are similar to the immunocompetent. The Laboratory Risk Indicator for Necrotizing Fasciitis score is not reliable for risk stratification of the disease.
