Onychomycosis Caused by Alternaria alternata: A Rare Case Report

Öz

Onychomycosis is a fungal infection of the nail unit caused by dermatophytes, non-dermatophyte molds, or yeasts. Among non-dermatophyte molds, Alternaria alternata is a dematiaceous fungus that only rarely involves the nail apparatus. Herein, we report a case of A. alternata–associated onychomycosis affecting a single toenail. Diagnosis was established by direct microscopy and culture, supported by characteristic morphological features. The patient was initiated on oral and topical terbinafine and remains under follow-up, with treatment response currently being monitored. This case highlights the diagnostic challenges and therapeutic considerations associated with rare non-dermatophyte mold infections of the nail.
