Constrictive bronchiolitis is characterized by the deposition of fibrous tissue between the bronchiolar epithelium and smooth muscle, resulting in irreversible narrowing of the bronchiolar lumen and fixed airflow obstruction
Dear Editor, Bronchiolitis is a generic term that includes a group of disorders with distinct etiologies, characterized by the presence of inflammation in small airways. 1 Constrictive bronchiolitis is a rare entity within this group.

Bronchiolitis is a common lung infection in young children and infants. It causes inflammation and congestion in the small airways (bronchioles) of the lung. Bronchiolitis is almost always caused by a virus. Typically, the peak time for bronchiolitis is during the winter months A pathologist uses the term, constrictive bronchiolitis,' and reports the lesion whether there is an airway obliteration or not. The clinical significance of the disease is usually associated with obliteration of the person's bronchiolar airways

In obliterative bronchiolitis, inflammation and fibrosis lead to narrowing or occlusion of bronchiolar lumina. To determine how bronchiolar structural alterations relate to lung physiology, 19 patients with a pathological diagnosis of obliterative bronchiolitis were studied. The bronchiolar inflammatory and fibrotic features were correlated to the clinical presentation, and lung function tests Constrictive bronchiolitis, also termed bronchiolitis obliterans and obliterative bronchiolitis, is an obstructive small airways disease identified in a variety of disorders (Table 10). Constrictive bronchiolitis is strongly associated with chronic lung transplant rejection, for which it is a significant cause of morbidity and mortality Constrictive bronchiolitis (CB) (or obliterative bronchiolitis) designates inflammation and fibrosis occurring predominantly in the walls and contiguous tissues of membranous and respiratory bronchioles, with resultant narrowing of their lumens. It differs from bronchiolitis obliterans-organizing pneumonia in its histopathology and clinical course. Most cases of CB occur in the setting of. Bronchiolitis is an acute inflammatory injury of the bronchioles that is usually caused by a viral infection. Although it may occur in persons of any age, severe symptoms are usually only evident in young infants; the larger airways of older children and adults better accommodate mucosal edema , Kendra L Fisher 2, Ranjit Waghray MBBS FRCPC SCAP3, Jody L Wright BSc MD FRCPC4, Sharon E Card MD MSc FRCPC5, Donald W Cockcroft MD FRPCC1 1Division of Respiratory Medicine; 2Department of Medical Imaging, Royal University Hospital; 3Department of Pathology, St Paul's Hospital, Saskatoon

Pathologic considerations. Am The anatomy of the small airways is discussed, and a pathologic classification applicable to the surgical pathology of bronchiolitis is presented.

Expert Rev Resp Med. 2007;1(1):139-147. Daud and colleagues found that among 334 lung-transplant recipients, 130 (39%) had grade 1 primary graft dysfunction, 69 (20%) had grade 2, and 70 (21%) had. Bronchiolitis obliterans is an inflammatory condition that affects the lung's tiniest airways, the bronchioles. In affected people, the bronchioles may become damaged and inflamed leading to extensive scarring that blocks the airways The pathology report of the explanted lung revealed acute and chronic bronchitis and constrictive bronchiolitis, bronchiectasis and bronchiololectasis. There were signs of organizing pneumonia with obliterative bronchiolitis of the upper lobes, consistent with RIOP (Figure 2 ) . Key words. small airways, inflammation, bronchiolitis. Introduction. (constrictive bronchiolitis)  Cryptogenic organizing pneumonia (COP), formerly known as bronchiolitis obliterans organizing pneumonia (BOOP), is an inflammation of the bronchioles (bronchiolitis) and surrounding tissue in the lungs. It is a form of idiopathic interstitial pneumonia.. It is often a complication of an existing chronic inflammatory disease such as rheumatoid arthritis, dermatomyositis, or it can be a side.
Constrictive bronchiolitis also has been reported in the course of rheumatoid arthritis, in certain other autoimmune diseases such as pemphigus vulgaris, after inhalation of toxic gases such as nitrogen oxide, after ingestion of certain drugs or medicinal agents such as Sauropus androgynous, and as a cryptogenic illness In the pathological examination of case 1, tissue changes supporting a diagnosis of constrictive bronchiolitis were observed; biopsy samples from two other cases were not diagnostic of bronchiolitis. However, these patients showed severe obstructive pulmonary defects and mosaic patterns on HRCT, and the negative biopsy results were probably due to a recognised sampling problem By emphasizing the extent of constrictive bronchiolitis in these specimens, we do not intend to minimize the contribution of infection, inflammation, and mucus plugging to CF lung disease pathology. Rather, our results emphasize that some of the irreversibility of CF lung function deterioration may be secondary to small airway remodeling that is not responsive to conventional therapy The pathology of small airways disease has been reviewed previously [8, 10-12] and, therefore, will not be extensively discussed here. called constrictive) bronchiolitis is characterised by narrowing of small airways related to patchy peribronchiolar fibrosis

This pattern of fibrosis radiating from and encompassing the diseased small airways is called airway-centered interstitial fibrosis and highlights bronchiolar pathology as the contributor to fibrosis ( Figure 3C )
Pathological evaluation. Biopsies were processed as previously described (3). An expert lung pathologist provided pathological interpretations. Constrictive bronchiolitis was diagnosed if either of the following were present with otherwise normal lung parenchyma:. Constrictive Bronchiolitis and Ulcerative Colitis Heather Ward, Kendra L Fisher, Ranjit Waghray, Jody L Wright, Sharon E Card, Donald W Cockcroft; Affiliations Department of Pathology, St Paul's Hospital, Saskatoon, Saskatchewan, Canad SUMMARY. Bronchiolitis is a generic term applied to a variety of inflammatory diseases that affect the bronchioles, sparing a considerable portion of the other parenchymal structures, in which both inflammatory cells and mesenchymal tissue are present. Bronchiolitis occurs in a variety of clinical settings and may be associated with large airway disease and parenchymal disease Save time identifying and diagnosing diseases of the lung, mediastinum and heart with Thoracic Pathology, a volume in the Highy Yield Pathology series. Edited by noted pathologist Dr. Aliya Husain, this medical reference book is designed to help you review the key pathologic features of a full range of thoracic diseases, recognize the classic look of typical specimens, and quickly confirm your. Bronchiolocentric fibrosis is essentially represented by the pathological pattern of constrictive fibrotic bronchiolitis obliterans. The corresponding clinical condition (obliterative bronchiolitis) is characterised by dyspnoea, airflow obstruction at lung function testing and air trapping with characteristic mosaic features on expiratory high resolution CT scans
