Anaerobic bacteremia and necrotizing fasciitis in a patient with Crohn's disease.

Crohn's disease is a chronic, granulomatous disease that affects the gut that is frequently treated with immunosuppressive therapy. Infectious complications are common and are usually related to the transmural nature of the inflammation, frequently manifesting as abscesses or perianal sepsis. Necrotizing fasciitis has not been reported in Crohn's disease. A case of a fatal necrotizing fasciitis in a patient with Crohn's disease after gut biopsies and corticosteroid therapy is reported.
