pneumonia, interstitial lung diseases, extrinsic allergic alveolitisAbstract
An excessive immune response to inhaled antigens in some susceptible individuals can cause hypersensitivity pneumonitis, considered a prevalent entity among diffuse interstitial lung diseases. A radical change in the classification of this undervalued entity has recently been proposed. In this report we describe the clinical and radiological characteristics of three cases of fibrotic hypersensitivity pneumonitis: bird keeper's lung, feather pillow lung, and chemical alveolitis. A table is shown with the probable occupations or risk exposures in our environment and an updated review of the subject is carried out.
