Allergic bronchopulmonary aspergillosis (ABPA) occurs in approximately 1-7.6% of patients with asthma. This incidence is low enough not to be considered in the differential diagnosis but also high enough to be an important disease. Since the symptoms and laboratory tests are not specific for ABPA, the diagnosis may be delay for years. However the failure to diagnose and treat ABPA for long term may result in fibrotic lung disease. This article focuses on the clinical and the laboratory aspects, and the management of ABPA in the light of three cases.
