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

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.

Phaeohyphomycosis caused by a plant pathogen, Corynespora cassiicola.

We report a case of subcutaneous phaeohyphomycosis caused by Corynespora cassiicola. Molecular identification of this pathogen on grasses confirms that it may be involved in human infection, as previously reported once in pre-molecular literature. In vitro antifungal susceptibility data of the strain are provided.
