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. | In lobar pneumonia the inflammation targets only one lobe.
