[Case of allergic bronchopulmonary aspergillosis triggered by relocation of residence].

A 22-year-old woman has been treated with inhaled corticosteroid for bronchial asthma. Her family moved house to Toyama prefecture in March 2003, and she was enrolled in our hospital. Her chest radiograph on first medical examination showed the right upper lobe infiltration. Bronchoscopy revealed a mucoid impaction at right B2, and Aspergillus fumigatus was cultured from suctioning of pulmonary secretions. Histopathologic findings from transbronchial biopsy revealed eosinophilic pneumonitis but not Aspergillus fumigatus. She was diagnosed allergic bronchopulmonary aspergillosis, and she was started on prednisolone 40 mg/day. The finding of her chest radiograph improved in two weeks. This case suggested that allergic bronchopulmonary aspergillosis was triggered by moving house with exposure of Aspergillus fumigatus. We should give guidance to asthmatics to wear a dust respirator at work in dust-laden environment.
