Abstract

Phaeohyphomycosis is a fungal infection common in immunocompromised patients such as those with hematologic malignancies, transplant recipients or under prolonged corticosteroid use. Here we describe a rare case of phaeohyphomycosis due to Biatriospora mackinnonii in a kidney transplant patient. We confirmed B. mackinnonii identity by sequencing of the internal transcribed spaces (ITS) region of ribosomal DNA (rDNA) and achieved a satisfactory therapeutic response with itraconazole administration.
