[Allergic bronchopulmonary aspergillosis; an important cause of asthma sometimes ignored].

The Authors describe a clinical case of allergic bronchopulmonary aspergillosis that remained unrecognized for a long time. The pathogenetic role of the environment, home climatology, and familiarity is considered. A possible therapeutic approach involving the use of associations of steroids and ketoconazole is also discussed. The Authors would like to draw the attention of physicians to forms of bronchial asthma with eosinophilia.
