Unusual occurrence of allergic bronchopulmonary aspergillosis in a family.

Allergic bronchopulmonary aspergillosis is now a well known entity in asthmatic patients. Despite the familial occurrence of bronchial asthma, the familiar occurrence of allergic bronchopulmonary aspergillosis is a rarity. Here 2 cases of allergic bronchopulmonary aspergillosis in a family (brother and sister), treated with prednisolone with complete remission are reported. The clinicans should have a high index of suspicion to investigate all the members of a patient with allergic bronchopulmonary aspergillosis, who are having history of asthma or rhinitis.
