Emergence of the Molds Other than Aspergillusin Immunocompromised Patients

Immunocompromised patients are at high risk for invasive fungal infections (IFIs); although Aspergillusremains the most common IFI caused by molds, other fungi, such as Mucorales, dematiaceous molds, and Fusariumspp, are being seen with increasing frequency. Presentations can vary, but sinopulmonary and disseminated infections are common. Our understanding of the pathogenesis of these infections is rudimentary. Fungal cultures and histopathology remain the backbone of diagnostics, as no good serologic markers are available. Polymerase chain reaction tests are being developed but currently remain investigational. Management of these infections is usually multidisciplinary, requiring surgical debridement along with antifungal therapy.
