Subcutaneous abscess caused by Chondrostereum purpureum, an unusual infection from plant to human: The first case report in a transplant recipient

Filamentous basidiomycetes have been recognized as emerging causes of human infection. <i>Schizophyllum commune</i> is the most frequently reported, whereas infections caused by other species are exceedingly rare. We report a case of subcutaneous abscess caused <i>by Chondrostereum purpureum</i> in a kidney transplant recipient. Definitive identification was achieved by sequencing the internal transcribed spacer and the D1/D2 regions. The patient was successfully treated with the surgical procedure and oral posaconazole. This report emphasizes the potential pathogenicity of plant fungi and the importance of molecular tools for identification.
