Case Report: Cutaneous Mycosis Caused by Purpureocillium lilacinum.

ABSTRACT: Purpureocillium lilacinum, widely used as a commercial biocontrol agent for controlling plant-parasitic nematodes, is an emerging opportunistic pathogen in humans and is increasingly reported, especially among immunocompromised patients.
