Hypersensitivity pneumonitis (HP), also known as extrinsic allergic alveolitis, is an immune mediated lung disease occurring in response to repeated inhalation of an antigen.

The diagnosis usually rests on a variable combina-tion of findings from history, serology, radiography, lung biopsy, and bronchoalveolar lavage, which characteristically reveals a lymphocyte content of more than 30%, often with an increased CD4-to-CD8 ratio of T cells. Treatment includes avoiding the allergen, if possible, Several diseases can cause BAL lymphocytosis —including sarcoidosis, infections, rheumatologic disorders, inflammatory bowel disease, radiation pneumonitis, drug-induced pulmonary reactions, cryptogenic organizing pneumonia, and NSIP—but in the appropriate clinical setting this finding is strongly suggestive of hypersensitivity pneumonitis.
