A Case of Toenail Onychomycosis Caused by Trichosporon asahii / 대한피부과학회지

ABSTRACT

We report the first case of toenail onychomycosis caused by Trichosporon asahii in a 60-year old Korean man. The patient presented with a typical distal subungual onychomycosis. Direct microscopic examination of scrapings on the potassium hydroxide(KOH) preparation revealed fungal elements. On modified dermatophyte agar, the colony was white color and wrinkled, folded with furrows and convolutions and microscopic morphology showed long rectangular arthroconidia and lateral blastoconidia of trichosporon species. The fungus was identified as T. asahii using API 20C AUX (bioMerieux S.A., l'Etolile, France) kit.
