Terminology
"Bronchiolitis obliterans" was originally a term used by pathologists to describe two patterns of airway disease, the other was bronchiolitis obliterans organizing pneumonia (BOOP), now known as cryptogenic organizing pneumonia. The name cryptogenic bronchiolitis obliterans is used when a cause is unknown.Bronchiolitis obliterans when it occurs following a lung transplant is known as bronchiolitis obliterans syndrome(BOS). BOS is defined as a person who has had either a HSCT or lung transplant and develops symptoms or radiographic findings consistent with bronchiolitis obliterans, but has not been confirmed by biopsy.
