Disseminated infection caused by <i>Emmonsia pasteuriana</i> in a renal transplant recipient

Abstract

Emmonsia pasteuriana is a thermally dimorphic fungus identified in very few human cases. Here, we report a case of a 43-year-old male renal transplant patient from China presenting with multiple painful skin eruptions on his head, nose and left thigh, later accompanied by respiratory failure. Histopathology of the biopsy collected from the left thigh upper ulcer and occipital nodule both demonstrated chronic inflammation with granuloma formation and yeast-like elements. Emmonsia pasteuriana was cultured from two biopsy specimens and their identity was confirmed by sequencing of the rDNA internal transcribed spacer. The patient in intensive care showed marked clinical improvement with antifungal treatment.
