Paecilomyces lilacinus Cellulitis in an Immunocompromised Patient

Abstract

Paecilomyces lilacinus, a saprophytic soil fungus, is an uncommon human pathogen. An immunocompromised patient developed a deep cellulitis due to P lilacinus. The infection responded poorly to intravenous amphotericin B but eventually resolved after combination therapy with amphotericin B and flucytosine (5-fluorocytosine). Previous in vitro studies have suggested that miconazole is the most active antifungal agent against P lilacinus.
