Abstract
Allergic fungal otomastoiditis, a rare known entity has only been published as case reports in literature. There have been 3 cases of adult and 1 case of pediatric allergic fungal otomastoiditis reported as of now. A young male had unilateral otorrhea and hearing difficulty for four years. The audiogram revealed moderate conductive hearing loss and radiograph showed complete opacification of tympanic cavity. He underwent tympano-mastoidectomy, showing polypoidal granulations and thick mucoid discharge. The histopathology was a surprise diagnosis of Allergic fungal otomastoiditis. The clinical and histopathological appearance of this entity matches allergic fungal rhinosinusitis. After extensive review of literature, we propose a working criterion for early identification of allergic fungal otomastoiditis in otolaryngology setting.
