Pathology What is the differencebetween bronchopneumonia and lobar pneumonia? (1, 2, 3) Image 1: A comparison image between bronchopneumonia and lobar pneumonia. Rather than looking at it as a single disease, health care professionals must remember that pneumonia is an umbrella term for a group of syndromes caused by a variety of organisms resulting in varied manifestations and sequelae. It therefore doesn’t care about the borders between the lobes; it crosses over them. normal lung parenchyma. x10), Figure 4 : Bronchopneumonia (detail) : central area of a focus of inflammatory condensation - Lobar pneumonia occurs in otherwise healthy individuals between 30 - 50 years of age. Note that there are some areas of lung which appear relatively normal, having a pale-staining appearance. The many small foci are the signs of bronchopneumonia. Lobar pneumonia. Extensive bronchopneumonia to lobar pneumonia with intra-alveolar neutrophils, macrophages, fibrin; often with leukocytoclastic neutrophilic infiltrate, small vessel vasculitis and necrosis Microscopic (histologic) images The appearance is consistent with confluent bronchopneumonia. Pathology. Bronchopneumonia:Characterized by patchy foci of consolidation (pus in many alveoli and adjacent air passages) scattered in one or more lobes of one or both lungs. ; Boeckh, M. (Nov 2010).

Bronchopneumonia occurs most frequently in infants, debilitated young children and elderly people, and in such patients often proves fatal. Bronchopneumonia affects one or more lobes, being frequently bilateral and basal. While a multi lobar pneumonia when more than one lobe of the lung is involved. Less common forms of infection include cellular bronchiolitis, septic embolism, miliary infection, and lung abscess. foci are separated by normal, aerated parenchyma.

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. On the other hand, bronchopneumonia affects both the bronchi and the lungs. Bronchopneumonia (Lobular pneumonia) There are two main types of acute bacterial pneumonia : bronchopneumonia (with lobular topography) and lobar pneumonia (lobar topography). Pneumonia is an acute exudative inflammation secondary to airborne infection with bacteria, viruses or mycoplasma. 3. (H&E, ob. Severe cases are associated with pulmonary abscesses, suppurative pleuritis, or septicemia. Bronchopneumonia. Note that the whole lung is affected, unlike in lobar pneumonia. This is a lobar pneumonia in which consolidation of the entire left upper lobe has occurred. The most common causes of CAP vary depending on a person's age, but they include Streptococcus pneumoniae, viruses, the atypical bacteria, and Haemophilus influenzae. The three most common patterns are lobar pneumonia, bronchopneumonia, and interstitial pneumonia. bronchia are filled with neutrophils ("leukocytic alveolitis").

Bronchopneumonia Occurs in infants, olds and those suffering from chronic debilitating illness or immunosuppression. There is diffuse consolidation of the whole of the lower lobe and much of the upper lobe. This pneumonia is bronchopneumonia since the distribution is along the bronchi and the terminal airway distribution throughout the lung. Red hepatization - day 2-4.
