title: Combined Allergic Bronchopulmonary Aspergillosis and Eosinophilic Granulomatosis with Polyangiitis: Three Cases and a Review of the Literature.
abstract: Previous reports of combined allergic bronchopulmonary mycosis (ABPM) and eosinophilic granulomatosis with polyangiitis (EGPA) are limited; however, among 41 cases of ABPM and 18 cases of EGPA treated at our hospital, we experienced three cases of combined ABPM and EGPA. In two of these cases, the diagnosis of EGPA preceded that of ABPM, however, one of the two cases had already shown findings suggestive of ABPM, such as mucous plugs and central bronchiectasis, at the time of the diagnosis of EGPA. In six previously reported cases of combined ABPM and EGPA, ABPM preceded EGPA in four cases. In the other two cases in which EGPA was diagnosed before or simultaneously with ABPM, findings suggestive of ABPM had been detected when EGPA was diagnosed, which suggests that sensitization to fungi resulting in ABPM may play an important role in the development of EGPA. Careful attention should therefore be paid to the possibility that these diseases may coexist during the course of either disease.
