Abstract: Hypersensitivity pneumonitis (HP), also referred to as extrinsic allergic alveolitis, is a pulmonary disease that occurs due to inhalational exposure to a variety of antigens leading to an inflammatory response of the alveoli and small airways. Wood dust is one of the oldest and one of the most common occupational exposures in the world. Here I present a case of 57 year old male non smoker, no previous history of tuberculosis whose occupation was stripping bark from maple logs for more than 10 years presented as lung fibrosis.
