Path Lung 3

Front 1

Back 1

Pt with bronchopneumonia, Bilateral patchy infiltrate

Front 2

Back 2

Lobar pneumonia: Strep pneumoniae, intraalveolar infiltrate
Left is bronchopneumonia
Right is lobar pneumonia

Front 3

Back 3

Multifocal areas of consolidation through the lung
Second pic is Multiple areas of induration and consolidation

Front 4

Back 4

Bronchioles full of pus, the neutrophils have gone out to the alveoli sacs and this is what corresponds to areas of consolidation.
Second pic is Pts can develop subplural abscess.

Front 5

Back 5

Lobar pneumoia…localized siteinvolving only one lobe (bronchopneumonia, there was bilateral patchy infiltrates)
Second pic is Lobe completely consolidated

Front 6

Back 6

lobar pneumoniae congestion Early disease..looks like edema

Front 7

Back 7

Lobar pneumonia Red hepatization

Front 8

Back 8

Lobar pneumoniae gray hepatization

Front 9

Back 9

Sputum with person with lobar pneumonia. Two things of significance, the background inflammatory cells are almost exclusively neutrophils. Characteristic bacteria stained strep pneumo.

Front 10

Back 10

Widening of alveoli septa is due to the infiltration of inflammatory cells. Widening causes irritation and causes the patients to cough but there is no pus

Front 11

Back 11

Severe case where there is diffuse alveolar damage, hyaline membrane formation
Atypical pneumoniae

Front 12

Back 12

Pt who died of pneuomia. Small bronchiole lined by cells with inclusions (adenovirus)
-atypical pneumonia

Front 13

Back 13

Heres a lung of a patient who pneumonia alba, rare finding.

Front 14

Back 14

Segment of lung tissue with sclerotic tissue, a ghon complex,

Front 15

Back 15

Manifestation of someone with secondary reactivated disease, it is a lung with miliary tb. It is patchy and multifocal and upper lobe cavitary disease, where the initial infection took place, reactivated and disseminated

Front 16

Back 16

Characteristic feat of the infection, you see caseating granulomas with necrosis in the center of granuloma
second pic is acid fast stain

Front 17

Back 17

Example of localized aspiration of pneumonia. Nothing tells you here that this is aspiration

Front 18

Back 18

Formed body vegetable material, indicative of aspiration

Front 19

Back 19

Disc like structures are pneumocystic. Not clinically signiciant unless immune system is compromised.
