Cutaneous hyalohyphomycosis due to Petriella setifera following traumatic inoculation in an immunocompetent host

Abstract A common cause of subcutaneous mycoses in immunocompetent patients is traumatic inoculation. This is the first reported case of cutaneous infection with Petriella setifera in a human host. A 49-year-old immunocompetent man sustained a splinter from his wooden deck, which resulted in a chronic cutaneous lesion. Originally identified as Scedosporium species on microscopic examination, genome sequencing of the internal transcribed spaces (ITS) region of ribosomal DNA (rDNA) identified the mold as Petriella setifera,a common environmental fungus responsible for wood rot. The patient underwent excision and antifungal therapy with cure.
