18 de ago. de 2022 · Pathogens: bacterial, viral, fungal. Clinical setting: community acquired pneumonia (CAP), hospital acquired pneumonia (HAP), ventilator associated pneumonia (VAP) Extent: Lobar pneumonia: involvement of the entire lung lobe. Bronchopneumonia: patchy involvement of the lung parenchyma, originating from the airway.
31 de jul. de 2023 · Histopathology. The histopathology in pneumonia can be broadly studied under 2 main headings: bronchopneumonia/lobular pneumonia or lobar pneumonia. Lobar Pneumonia. Lobar pneumonia is diffuse consolidation involving the entire lobe of the lung. Its evolvement can be broken down into 4 stages as follows:
6 de feb. de 2014 · Bronchopneumonia (Lobular pneumonia) is an acute exudative suppurative inflammation of the lungs characterized by foci of consolidation surrounded by normal parenchyma. Generally, it is produced by bacteria : staphylococcus, streptococcus, Haemophilus influenzae, proteus, Escherichia coli.
Bronchopneumonia. Bronchopneumonia occurs when the infection begins within the bronchi/bronchioles, and then descends into the nearby alveoli. Because of this, consolidation of the alveoli occurs in patches around the affected bronchi/bronchioles.
Definition / general. Organizing pneumonia (OP) can be defined as either clinicopathological diagnosis, histological pattern or microscopic findings. Histologic features include polypoid fibroblastic aggregations, which plug alveolar sacs, ducts and bronchioles. Essential features.
Pathologic Features. Bronchopneumonia (i.e., lobular pneumonia) results when organisms are deposited in the epithelium of peripheral airways (i.e., distal bronchi or bronchioles), resulting in epithelial ulcerations and formation of a peribronchiolar exudate.
mixed with epithelium, pus, and sometimes blood. After death the only lesions visible are the increased quantity of mucus, the growth of new epithelium, a few pus cells infiltrating the stroma of ...
