Onychomycosis caused by Pichia guilliermondii: a case report and mini-review

Abstract Onychomycosis has been reported to be mainly caused by dermatophytes. Recently, more attention has been paid to yeast for its increasing morbidity, especially the candida specices. Here we reported a fingernail infection caused by Pichia guilliermondii, the sexual reproduction period of Candida guilliermondii. Itraconazole was used for three courses, and the patient achieved improvement without any significant side-effects. This might be the first onychomycosis case of Candida guilliermondii.
