A case of onychomycosis caused by a terbinafine-susceptible Fusarium solani in Vietnam

Fusarium spp. are the common onychomycosis pathogens in non-dermatophyte molds, and are considered resistant to many antifungal agents. We reported onychomycosis of the fingernail caused by Fusarium solani in Vietnam. The minimum inhib-itory concentration of terbinafine against the tested isolate was 1�g/ml, which was the lowest of all antimycotic agents. The patient was successfully treated with a daily dose of 250mg terbinafine for two months, and no recurrence occurred after a one-year follow-up. Antifungal susceptibility testing is recommended in Fusarium onychomycosis. � 2022 The Authors. Published by Tehran University of Medical Sciences.
