-
A condition in which the bronchioles (tiny branches of air tubes in the lungs) become inflamed and blocked. It may be caused by breathing in gases or particles that irritate the bronchioles. This irritation causes scar tissue to form, and makes breathing difficult. Bronchiolitis olbiterans may be caused by other factors, and can also occur after a transplant with an organ or stem cells from a matched donor.NCI Dictionary of Cancer TermsU.S. National Cancer Institute, 2021

Inflammation and fibrosis of the bronchioles leading to partial or complete obstruction of these airways.Human Phenotype Ontology (HPO)The Human Phenotype Ontology Project, 2021
