| bronchiolitis obliterans organizing pneumonia | A disease formerly considered a form of interstitial pneumonia. Its aetiology is obscure but it may be associated with toxic fumes, infection, and connective tissue disease. Clinical symptoms include cough, dyspnea and influenza-like symptoms with the development of the usual interstitial pneumonia in many cases. Obstructive symptoms are limited to smokers. There are patchy polypoid masses of intra-alveolar granulation tissue in small airway lumina and alveolar ducts. "organizing" refers to unresolved pneumonia (in which the alveolar exudate persists and eventually undergoes fibrosis) in which fibrous tissue forms in the alveoli. (12 Dec 1998) |

| bronchiolitis obliterans with organizing pneumonia | Bronchiolitis fibrosa obliterans complicated by pneumonia with organization. Acronym: BOOP (05 Mar 2000) |
| bronchiolitis, viral | An acute inflammatory disease of the upper respiratory tract, caused by paramyxoviruses, occurring primarily in infants and young children; the viruses most commonly implicated are parainfluenza type 3 and respiratory syncytial virus. (12 Dec 1998) |
| bronchiolo- | Bronchiole. Origin: L. Bronchiolus (05 Mar 2000) |
| bronchiolo-alveolar carcinoma | <tumour> A carcinoma, thought to be derived from epithelium of terminal bronchioles, in which the neoplastic tissue extends along the alveolar walls and grows in small masses within the alveoli; involvement may be uniformly diffuse and massive, or nodular, or lobular; microscopically, the neoplastic cells are cuboidal or columnar and form papillary structures; mucin may be demonstrated in some of the cells and in the material in the alveoli, which also includes denuded cells; metastases in regional lymph nodes, and even in more distant sites, are known to occur, but are infrequent. Synonym: alveolar cell carcinoma, bronchiolar adenocarcinoma, bronchiolo-alveolar carcinoma, bronchioloalveolar adenocarcinoma. (05 Mar 2000) |

| bronchiolus | Synonym: bronchiole. Origin: Mod. L. Dim. Of bronchus (05 Mar 2000) |
| bronchiolus terminalis | The end of the nonrespiratory conducting airway; the lining is simple columnar or cuboidal epithelium without mucous goblet cells; most of the cells are ciliated, but a few nonciliated serous secreting cells occur. Synonym: bronchiolus terminalis. (05 Mar 2000) |

| bronchitis | <chest medicine> Inflammation of one or more bronchi, usually secondary to infection. (13 Nov 1997) |
| bronchitis obliterans | Fibrinous bronchitis in which the exudate is not expectorated but becomes organised, obliterating the affected portion of the bronchial tubes with consequent permanent collapse of affected portions of the lung. (05 Mar 2000) |
| bronchium | Synonym: bronchus. Origin: Mod. L. Fr. G. Bronchion (05 Mar 2000) |
