[Allergic Aspergillus sinusitis].

The leading symptom of the allergic aspergillus sinusitis is the accumulation of mucoid material, Charcot-Leyden crystals and scattered aspergillus hyphae can usually be found. The mucosa itself shows a typically allergic reaction with distinct eosinophilia and additional inflammatory infiltrates. The histological and serological appearance of the allergic aspergillus sinusitis resembles that of allergic bronchopulmonary aspergillosis. The relation between these syndrome, as well as the treatment of allergic aspergillus sinusitis, are discussed.
