Subcutaneous gluteal abscess from Trichosporon asahii in an immunocompetent adult.

Fungal infections have been drastically increasing in incidence in recent years, preferentially affecting immunocompromised hosts and causing potentially fatal outcomes. One of the emerging fatal fungal pathogens is Trichosporon asahii, a non-Candida yeast that has been increasingly reported in recent years. Previous literature has described T. asahii as primarily affecting immunocompromised hosts, specifically those who are neutropenic, and causing fatal disseminated infections. Herein, we describe a case of an isolated subcutaneous abscess with T. asahii in an immunocompetent host without overlying skin manifestations or predisposing factors that resulted in complete mycotic cure when treated with voriconazole and terbinafine.
