title: Hypersensitive pneumonitis: a case report.
abstract: Hypersensitivity pneumonitis, also known as extrinsic allergic alveolitis, constitutes a spectrum of granulomatous, interstitial, bronchiolar, and alveolar-filling lung diseases resulting from repeated inhalation and sensitization to a wide variety of organic aerosols and low-molecular-weight chemical antigens. We report a case of a 57 year-old-female with hypersensitive pneumonitis due to pigeon droppings. Early diagnosis during the acute phase of hypersensitive pneumonitis is important due to the irreversible damages caused by this chronic disease.
