A Case of Onychomycosis Caused by Fusarium verticillioides / 대한의진균학회지

ABSTRACT

Onychomycosis is caused by dermatophytes usually, but some species of non-dermatophytic molds and yeasts are also associated with invasion of nails. Fusarium (F.) verticillioides is a non-dermatophytic mold, which are common soil saprophytes. Onychomycosis due to Fusarium species almost always involves great toe nails and occurs infection easily in the presence of trauma, onychodystrophy and prior onychomycosis. We report a first case of onychomycosis caused by Fusarium verticillioides in a 48-year-old man. He presented with proximal white superficial onychomycosis for 3 months. Fungal culture showed whitish cottony colonies and microscopic examination of colonies showed microconidia in a chain from monophialide. We diagnosed onychomycosis caused by Fusarium verticillioides and treated by itraconazole 200 mg daily and 5% amorolfine nail lacquer for 3 months.
