title: Allergic fungal rhinosinusitis: a report of 8 cases.
abstract: Eight patients presented with clinical manifestations such as polyps and mucin were reported to have allergic fungal rhinosinusitis (AFS). Histopathologic sections from tissue samples containing mucin from the paranasal sinuses obtained by endoscopic operation showed scattered hyphal elements within the allergic mucin but no tissue invasion. Associated fungi were 4 cases of Aspergillus flavus; a case each of Aspergillus niger and Bipolaris hawaiiensis, mixed colonization with B. hawaiiensis, and Curvularia lunata; and 1 case of Bipolaris species. Elevated immunoglobulin E level was reported in some patients ranging from (706 to 1969 IU/mL). All patients underwent endoscopic surgery; polypectomy and clearance of all affected sinuses were performed. Medical treatment involved the use of local and systemic corticosteroids. The patients have done well, with no evidence of recurrent disease.
