This case highlights the importance of black yeast-like fungi as etiological agents of onychomycosis and identifies the isolate as resistant to fluconazole and the echinocandins.
Abstract
A 46-year-old woman from Colombia, without any medical comorbidities, presented with marked yellowish discoloration of both big toenails, suggestive of onychomycosis, and malalignment of the nail plate. Culture of nail scrapings grew dark-pigmented, mucoid, yeast-like colonies identified as Exophiala alcalophila by ITS sequencing. Broth microdilution identified the isolate as resistant to fluconazole and the echinocandins. The patient refused antifungal treatment. This case highlights the importance of black yeast-like fungi as etiological agents of onychomycosis.
We report 2 cases of chronic subcutaneous infection in immunocompetent persons caused by Fomitiporella spp. basidiomycetes. Both patients recovered after surgical excision without antifungal therapy. We confirmed the cause of infection using broad-range fungal PCR from formalin-fixed tissue, highlighting the value of m...
