Abstract

Hypersensitivity pneumonitis is an immunologically mediated disease resulted from repeated exposure to sensitizing agents such as organic dusts or chemicals. We report two cases of familial hypersensitivity pneumonitis diagnosed by typical symptoms, physical findings, chest x-ray abnormalities, and histologic findings with a brief review of the literature. A 60-year-old woman and her 62-year-old husband successively presented with dry cough and exertional dyspnea. These symptoms developed about 20 days after the womon had started feeding cows with stored hay. The same symptoms also developed in her husband when he had handled the stored hay instead of her because of her illness. We confirmed hypersensitivity pneumonitis with bronchoalveolar lavage fluid analysis and open and transbronchial lung biopsies.
