Morphological findings of deep cutaneous fungal infections.

Cutaneous fungal infections used to be rare in most developed countries. However, they have become more common due to immunosuppression and globalization. In this report, we summarize the histopathologic findings of the main cutaneous fungal infections that are commonly seen in daily practice, including eumycetoma, sporotrichosis, histoplasmosis, cryptococcosis, coccidioidomycosis, aspergillosis, zygomycosis, phaeohyphomycosis, alternariosis, blastomycosis, paracoccidioidomycosis, lobomycosis, and chromoblastomycosis. We also include protothecosis (despite the fact that the infectious agent of this disease is algal and not fungal) and rhinosporidiosis (despite being caused by mesomycetozoea, which are not fungi).
