Allergic fungal rhinosinusitis--a case report.

Allergic fungal rhinosinusitis is a unique disorder characterised by specific immunological hypersensitivity to certain fungal antigens usually presenting with nasal polyps and characteristic CT findings. It is a noninvasive disease and on histopathology shows formation of allergic mucin containing numerous eosinophils, charcot leyden crystals and scattered fungal hyphae. Many cases have been reported in western journals but it has been rarely reported in Indian literature. This case is probably the first case in India. It is presented here for its rarity.
