Histoplasma capsulatum prosthetic joint infection

Abstract

Immunocompromised patients are at risk of opportunistic infections. This is a 67-year-old woman with systemic sclerosis and knee osteoarthritis who underwent left total knee arthroplasty in 2009. In 2018 she underwent surgery for presumed aseptic loosening. Inflammation and purulent fluid were found; implant was removed and replaced with a static spacer. Three weeks later, H. capsulatum was isolated. She was successfully treated with itraconazole for 18 months; cultures on revision spacer replacement surgery were negative.
