A rare case of onychomycosis caused by Emericella quadrilineata (Aspergillus tetrazonus).

Onychomycosis is a common chronic nail disorder where dermatophytes are the predominant pathogens. However, non‑dermatophytic moulds like Aspergillus can also be implicated as the causative agents. Herein, we report a rare case of onychomycosis due to Emericella quadrilineata (Aspergillus tetrazonus) in an apparently immunocompetent host.
