Allergic Fungal Sinusitis: A Review with Four Illustrated Cases

Abstract

Although paranasal fungal sinusitis is rare, an increased number of Aspergillus and non-Aspergillus related cases of allergic fungal sinusitis have been described since its first report in 1983. The histopathologic findings necessary for a definitive diagnosis rest upon the detection of scattered fungal elements in a matrix of allergic mucin. The clinical spectrum and treatment of allergic fungal sinusitis are detailed within four illustrated case reports. Sinus surgery, followed by meticulous post-surgical care by an allergy and otolaryngology team using oral corticosteroids, and followed by maintenance intranasal steroids and nasal airway irrigations in conjunction with allergy immunotherapy, has resulted in excellent clinical outcomes.
