Staining: HE

Organ: Lung

Description:

The slide has two different parts. The left part shows no significant amount of inflammatory cells in the alveoli.

The right part is diffusely inflamed. The alveoli in the right part contains exudate and neutrophils.

Diagnosis: Lobar pneumonia

Theory:

In lobar pneumonia the inflammation targets only one lobe. The infection does not cross the border to other lobes, however the lobe that is infected is diffusely infiltrated by neutrophils. There are no foci, as there is in bronchopneumonia.

The alveoli contain purulent exudate (pus), which consists of neutrophils, necrotic cells and oedema fluid. This is therefore the purulent stage of pneumonia.

Overview of the slide
The alveolar structure is even harder to find here
Alveoli filled with neutrophils mostly
