Cutaneous hyalohyphomycosis caused by Purpureocillium lilacinum in an immunocompetent patient: Case report and review

Abstract

Purpureocillium lilacinum is a saprophytic fungus found in soil and decaying organic matter, but has been reported as an emerging pathogen in immunocompromised patients and following surgical procedures. Infections caused by this mold are often difficult to treat because of its intrinsic resistance to conventional antifungal agents and variable susceptibility to novel triazoles. In immunocompetent subjects, infections caused by P. lilacinum are unusual and mainly involve the skin. We describe herein a case of cutaneous hyalohyphomycosis due to this fungus in an immunocompetent girl without any predisposing risk factors and review the previously reported cases in immunocompetent hosts. © 2013 ISHAM.
