[Two cases of summer-type hypersensitivity peumonitis with remarkable changes in the bronchioles].
A 56-year-old man and a 53-year-old woman with cough, sputum and dyspnea were admitted in the summer. High-resolution computed tomographic findings of the chest showed centrilobular branching opacities like diffuse panbronchiolitis with ground glass opacities. Both cases showed hypoxia, a high titer of serum anti-Tricosporon antibody and exacerbation in their own homes. Video-assisted thoracoscopic lung biopsy revealed granuloma in the bronchioles area. We diagnosed summer type hypersensitivity pneumonitis and this condition improved in response to antigen isolation and steroids. Remarkable changes in the bronchioles were characteristic in the two cases.
