First report of subcutaneous phaeohyphomycosis caused by Ochroconis tshawytschae in an immunocompetent patient

Abstract

We report the first case and clinical course of a case of human subcutaneous phaeohyphomycosis caused by Ochroconis tshawytschae, a rare fish pathogen. The diagnosis was based upon histopathological and mycological examinations of clinical samples. Identification of the etiologic agent was assessed on its phenotypic characteristics and subsequently, confirmed by molecular data. In vitro antifungal susceptibility of the isolate was investigated and a comparison was prepared of all of its features to those of its two most relevant related species, O. gallopava and O. humicola. © 2012 ISHAM.
