Use of the terms without qualification is discouraged... as they do not make explicit the etiology. Microscopy : foci of inflammatory condensation centered by a bronchiole with acute bronchiolitis (suppurative exudate rich in This pattern is much less common than the bronchopneumonia pattern. Lesion is more extensive at the base of the lung and often fuses together resembling lobar pneumonia (confluent bronchopneumonia). Pneumonia has been defined as an infection of the lung parenchyma. "CMV in critically ill patients: pathogen or bystander?". Lobar Pneumonia is the infection which is restricted or a single lobe or a part of the lung.

On the other hand, bronchopneumonia affects both the bronchi and the lungs. Panlobar pneumonia involves all the lobes of a single lung. Stage 1: Congestion, due to congested vessels and edema. Less common forms of infection include cellular bronchiolitis, septic embolism, miliary infection, and lung abscess. Lobar or bronchopneumonia and occasionally aspiration pneumonia are important differential diagnoses for respiratory problems. Bronchopneumoniaaffects small breathing ways (bronchioli) and small parts of the lung tissue around them (lobuli); an X-ray shows small white patches scattered over the large area of, usually both, lung wings. Tutorial contains images and text for pathology education. Bronchopneumonia (Lobular pneumonia) is an acute exudative suppurative inflammation of the lungs characterized by foci of consolidation surrounded by normal parenchyma.

Atypical mycobacterium, e.g. Multiple foci of (acute) inflammation involving the bronchi. Compared to lobar pneumonia, which involves 1 or more lobes, bronchopneumonia is patchy, involving only small bronchioles and … Severe cases are associated with pulmonary abscesses, suppurative pleuritis, or septicemia. Search. Bronchopneumonia: Classically yellow-white centered on the bronchi. Bacterial pneumonia is more common, either occurring as a primary entity or a complication to some other illness. characterized by foci of consolidation surrounded by normal parenchyma. Bronchopneumonia occurs most frequently in infants, debilitated young children and elderly people, and in such patients often proves fatal. Morphology of Lobar pneumonia A large portion of one lobe or entire lobe of the lung is involved In the initial stages, it can appear as bronchopneumonia with patchy involvement, the patches can later coalesce to give rise to lobar pneumonia. http://www.pathologyoutlines.com/topic/lungnontumorCMV.html, https://librepathology.org/w/index.php?title=Pneumonia&oldid=47045, Attribution-NonCommercial-ShareAlike 4.0 International.

Eosinophilic granular cytoplasmic inclusions. Lobar pneumonia/bronchopneumonia is used to described consolidations affecting secondary lung lobules, usually secondary to bacterial infections such as Staphylococcus aureus among others. Bronchopneumonia is usually a bacterial pneumonia rather than being caused by viral disease.
