Disease Etiology
There are many different fungal species that can be invasive, but the most common are the Zygomycetes (Muror, Rhizopus, and Rhizomucor) and Aspergillus species.
Histology
Histologic evaluation is necessary to determine the species of invasion, which can influence treatment decisions with respect to antifungal coverage. Mucor and Rhizopus are both characterized by non-septate fungal hyphae with 90-degree angle branching. Aspergillus also has non-septate hyphae, but typically has 45-degree angle branching.
