Two cases of allergic fungal rhinosinusitis caused by alternaria

Abstract

We herein report two cases of allergic fungal rhinosinusitis due to Alternaria. Allergic fungal rhinosinusitis is a relatively rare disease, and unless the disease is suspected, even its pathological diagnosis is difficult. For the treatment of refractory fungal sinusitis with multiple relapses, it is important to take the existence of allergic fungal rhinosinusitis into account when making a differential diagnosis.
