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

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.
