A Case of Fingernail Onychomycosis Caused by Fusarium proliferatum / 대한의진균학회지

ABSTRACT

Onychomycosis is a fungal nail infection caused mainly by dermatophytes. Non-dermatophytes such as yeasts, Acremonium, Aspergillus, and Fusarium species account for only 10% of onychomycosis, and Fusarium species are relatively common amongst these pathogens. However, the main Fusarium species pathogens are Fusarium solani and Fusarium oxysporum. Fusarium proliferatum is a rare pathogen in onychomycosis, and only a few cases have been reported worldwide. We report a case of a 68-year-old woman presenting with a white- to yellow-colored patch on her left third fingernail plate, which was diagnosed by fungus culture and sequencing as onychomycosis caused by Fusarium proliferatum.
