Schizophyllum commune maxillary sinusitis in an immunocompromised patient: A case report

ABSTRACT

Schizophyllum commune is a basidiomycotic fungus that grows ubiquitously on trees and rotting wood. Human infections caused by it are of diverse presentation but are very rare. We present a case of sinusitis caused by S. commune in a 58-year-old female patient with post-COVID-19 infection along with a history of allergic rhinitis and diabetes mellitus type 2. Computed tomography scan findings established the clinical diagnosis of fungal maxillary sinusitis which was confirmed with culture report and polymerase chain reaction followed by sequencing. The patient underwent functional endoscopic sinus surgery. She was treated empirically with itraconazole after surgical excision
