Abstract
Onychomycosis is an uncommon disease in pediatric patients with dermatophytes and Candida spp. being the main causative agents. Kodamaea ohmeri has recently emerged as a human pathogen, including an onychomycosis causative agent. Here, we report the first case of childhood onychomycosis caused by K. ohmeri in Vietnam, presenting clinically as a white superficial onychomycosis. Fungal identification was confirmed by sequencing of the ITS1-2 region. Antifungal susceptibility testing revealed low minimum inhibitory concentrations for all tested agents, except fluconazole and caspofungin. The patient was treated with 2 % ketoconazole cream one month, resulting in complete resolution of the nail damage with no relapse observed after six months.
