histology of consolidation
depending on the stage of the inflammatory response (early red hepatization or later grey
hepatization), the alveolar spaces are filled with protein-rich fluid and red cells or pmns
and macrophages, respectively. alveolar walls generally remain intact. large airways are
often free of exudate.
most of the inflammatory cells here are pmns or macrophages corresponding to a gross
appearance of grey hepatization. |
