How prevalent are fungal infections in the differential diagnosis of chronic sinusitis?—JANICE SKINNER, CRNP, Sykesville, Md.
Fungal sinus infections occur primarily in immunosuppressed patients and those with poorly controlled diabetes. Suspected cases of fungal sinusitis warrant immediate consultation with an ENT specialist. The diagnosis is confirmed by endoscopic examination and biopsy of the mucosa.
