FIRST PARAGRAPH: Allergic fungal sinusitis, also known as allergic mucin and eosinophilic fungal rhinosinusitis, is an allergic response in the sinonasal tract mucosa to aerosolized fungal allergens, amplified and perpetuated by eosinophils. The class II genes in the major histocompatibility complex are involved in antigen presentation and immune response (modulation), and an allergic reaction develops to inhaled fungal elements in immunocompetent people. Aspergillus species are the most common agents (widespread in soil, wood, and decomposing plant material), but Alternaria, Bipolaris, Curvularia, Exserohilum, and Phialophora species have also been reported
