Respiratory bronchiolitis is a lung disease associated with tobacco smoking. In pathology, it is defined by the presence of smoker's macrophages. When manifesting significant clinical symptoms it is referred to as respiratory bronchiolitis interstitial lung disease (RB-ILD) The term bronchiolitis has been historically confusing to clinicians and pathologists alike. Bronchiolitis is inconsistently applied as both a descriptive and a formal diagnostic term in part because bronchiolitis comprises a heterogeneous group of etiologically, clinically, and pathologically disparate lesions ().In addition, many of these conditions are complicated by pathologic. Diffuse panbronchiolitis (DPB) is a rare clinicopathologic syndrome characterized by bronchiolitis and chronic sinusitis [ 1,2 ]. In the disease name, diffuse refers to the distribution of the lesions throughout both lungs and pan refers to the pathologic finding that the inflammation involves all layers of the respiratory bronchioles [ 1 ] Pathology Outlines - Respiratory bronchioliti .

Respiratory bronchiolitis - Respiratory (or smoker's) bronchiolitis (RB) is a well-recognized pathological lesion found in the lungs of cigarette smokers that is generally not associated with respiratory symptoms. The key histopathologic features of RB are the presence of tan-pigmented macrophages (also known as smokers' macrophages) in the. ,defined as permanent dilation of bronchi and bronchioles due to destruction of smooth muscle and elastic tissue by chronic necrotising infections Abstract We have identified 25 lesions involving alveolar lung parenchyma characterized by nodular proliferation of bland bilayered bronchiolar-type epithelium containing a continuous layer of basal cells

Chronic rejection of the lung allograft is defined as a fibrosing process affecting the lung, which primarily affects the conducting airways and the pulmonary vasculature. The process affecting the conducting airways has been labeled bronchiolitis. Bronchiolitis obliterans organizing pneumonia (BOOP) was described in 1985 1 as a distinct entity, with different clinical, radiographic, and prognostic features than the airway disorder obliterative bronchiolitis 2 and the interstitial fibrotic lung disorder usual interstitial pneumonia/idiopathic pulmonary fibrosis (UIP/IPF). 3 BOOP is characterized by polyploid endobronchial connective.

The latter represents the innate and adaptive immune responses to long term exposure to noxious particles and gases, particularly cigarette smoke
pathology narrative should include a description of the morphologic features of the pigment, its distribution within the tissue, and the cell type affected. Associated lesions, such as hemorrhage, alveolar macrophage infiltration, or inflammation, should be diagnosed separately Granulomatous lung diseases are a heterogeneous group of disorders that have a wide spectrum of pathologies with variable clinical manifestations and outcomes. Precise clinical evaluation, laboratory testing, pulmonary function testing, radiological imaging including high-resolution computed tomography and often histopathological assessment contribute to make a confident diagnosis of. Respiratory | Trachea, bronchioles and bronchi. The conducting portion is made up of: nasal cavities, nasopharynx, larynx, trachea, bronchii and bronchioles.

Patients with diffuse alveolar damage can be very sick and may be admitted to the intensive care unit The respiratory tract, diaphragm and lungs do form early in embryonic development.

BOOP is a nonspecific histopathologic pattern of lung injury that can be a manifestation of pulmonary drug toxicity.

Pathology noted that the tissue showed smoking-related diffuse parenchymal lung disease with localized ﬁbrosis and peribronchiolar metaplasia. DISCUSSION: Bronchiolar metaplasia is a reactive condition where bronchiolar epithelium extends beyond respiratory bronchioles along the alveolar septa and replaces normal alveolar lining cells Smoking-related interstitial fibrosis (SRIF) is a common, histologically striking finding in smokers that must be distinguished from the idiopathic interstitial pneumonias and other chronic interstitial fibrosing lesions. It is characterised by marked thickening of alveolar septa by fibrosis composed of thick collagen bundles that have a distinctive hyalinised quality and often are admixed. During the canalicular or acinar phase (16-28 weeks gestation), multiple alveolar ducts arise from respiratory bronchioles (, Fig 4). Alveolar ducts are lined by type II alveolar cells, which are capable of surfactant synthesis. Thin type I alveolar lining cells differentiate from type II cells

Nonspecific interstitial pneumonia (NSIP) is now a separate specific form of pulmonary fibrosis.

Respiratory syncytial (sin-SISH-uhl) virus, or RSV, is a common respiratory virus that usually causes mild, cold-like symptoms. Most people recover in a week or two, but RSV can be serious, especially for infants and older adults.

The term asbestosis refers to diffuse interstitial pulmonary fibrosis consequent to the excess inhalation of asbestos fibres.

The condition damages the tiniest airways in your lungs (bronchioles), causing coughing and shortness of breath. Read More PLCH is one manifestation of Langerhans cell histiocytosis, which can affect many organs (most notably the lungs, skin, bones, pituitary, and lymph nodes) in isolation or simultaneously.

This consists of the trachea, 2 main bronchi and bronchioles right upto the terminal bronchioles. The other functions of the airways or ducts are moistening and filtering of air before it reaches the blood-air barrier for exchange. 2. The respiratory portion. This consists of the respiratory bronchioles, alveolar ducts and alveolar sacs Pathology. In follicular bronchiolitis, numerous lymphoid follicles with associated reactive germinal centers are present around bronchi and bronchioles. The bronchiolar lumens are sometimes compressed. Lymphocytes extend into and permeate the adjacent bronchial or bronchiolar epithelium Talcosis, a granulomatous inflammation of the lungs caused by inhalation of talcum dust, is a rare form of pneumoconiosis. Besides inhalative occupational exposure, intravenous abuse of adulterated drugs is a major cause for this condition. Minerals such as talcum (magnesium silicate) and sand (predominant silicon dioxide) are used to increase both volume and weight of illicit substances COWS close their glottis and grunt when they are dying. This leads to air being unable to escape and causes alveolar septae to break, causing ________. True or False: Mycobacterium bovis can cause a multifocal pattern of granulomatous nodules in the lungs of a COW. These lymph nodes are located near the bifurcation of the trachea
The respiratory or gas-exchange region of the lung is composed of millions of alveoli, which are lined by an extremely thin, simple squamous epithelium that allows for the easy diffusion of oxygen and carbon dioxide.
