A case of chronic necrotizing pulmonary aspergillosis due toAspergillus nidulans

Abstract
A 55-year old man without immunosuppression clinically showed a coin lesion in the right lower lung on the chest radiographs.Aspergillus nidulans was isolated and identified in both trans-bronchial lung biopsy specimen and resected tissue. The specimens revealed characteristics of chronic necrotizing pulmonary aspergillosis pathologically. Very few reports on cases of pulmonary aspergillosis due toA. nidulans exist, and we were not able to find any reports of similar cases. This case may be the first reported case of chronic necrotizing pulmonary aspergillosis due toA. nidulans.
