The Evaluation of the Sensitivity and Specificity of a New Endoscopic Diagnostic Sign of Allergic Fungal Rhinosinusitis: Intrapolypoidal White Particles.

Purpose: The diagnostic criteria of allergic fungal rhinosinusitis focus on characteristic clinical, radiographic, histopathologic findings and immunologic characteristics of the disease. None of these are useful for a prompt outpatient diagnosis of the condition. No clear endoscopic signs (pathognomonic) of polyps in allergic fungal rhinosinusitis are mentioned in the literature.
