Allergic bronchopulmonary aspergillosis (ABPA) is an allergic disease caused by viable Aspergillus in a relatively large bronchus and by the type I and type III allergies against the fungus. The clinical findings are characterized by recurrent pyrexial attacks (fever, cough and mucopurulent sputum containing mucous plugs, numerous eosinophils and the fungus), radiological evidence of recurrent collapse and consolidation in different areas of the lung, a blood eosinophilia and elevated serum IgE levels. Fungi other than Aspergillus may cause similar allergological diseases. Therefore, they should be call allergic bronchopulmonary fungal diseases (ABPF). Many diagnostic criteria of the disease have been proposed by many different authors, but, a return should be made to the original report by Hinson et al, 1952.
