Diagnosis: Allergic fungal rhinosinusitis (AFRS)
Allergic fungal rhinosinusitis, which is a noninvasive form of chronic rhinosinusitis caused by fungi, was first described in 1976 in a patient with allergic bronchopulmonary aspergillosis.1 Initially, it was thought to be a component of allergic bronchopulmonary aspergillosis; however, in 1989, a review of surgical specimens from patients with chronic rhinosinusitis revealed that it is a distinct entity.2
