[Invasive zygomycosis: notably in diabetes mellitus and iron overload].

The incidence of invasive zygomycosis, a severe and often life-threatening infection, is increasing. The most common manifestations are pulmonary infection (following anti-cancer chemotherapy or haematopoietic stem-cell transplant) and invasive rhinocerebral infection (in patients with diabetes mellitus or iron overload). Iron metabolism plays an important role in the pathogenesis of infection in these high-risk populations. Rapid diagnosis, reversal of the underlying predisposition and timely surgical debridement are the underlying principles of therapy for this disease.
