Invasive fungal infection in an elderly patient with defective inflammatory macrophage function

Abstract

Macrophages are known to be involved in pathogen recognition and mediate host immune responses, but, in the clinical setting, their purported central role in opportunistic fungal infections has not been demonstrated to date. Herein, we describe a patient with invasive testicular aspergillosis in whom we found, for the first time, a defect in macrophage function.
