Chronic Elbow Nodules Caused by Fomitiporella Fungus in Immunocompetent Patients, United States

Abstract

We report 2 cases of chronic subcutaneous infection in immunocompetent persons caused by Fomitiporella spp. basidiomycetes. Both patients recovered after surgical excision without antifungal therapy. We confirmed the cause of infection using broad-range fungal PCR from formalin-fixed tissue, highlighting the value of molecular diagnostics for detecting rare environmental fungi.
