Mucormycosis (previously called zygomycosis) is a serious but rare fungal infection caused by a group of molds called mucormycetes. Rhinocerebral mucormycosis is the most common clinical form. FINDINGS: To cause disease, fungal spores need to evade the innate immune system and germinate, leading to angioinvasion and tissue destruction. Fungi of the basal lineage order Mucorales are able to cause infections in animals and humans. Diabetic or immunocompromised patients most commonly present with ©2000-2021 ITHAKA.
