hepatization
Definition
- Noun (Medicine/Pathology):
- hepatization refers to the pathological process in which lung tissue becomes solidified and takes on a texture and appearance resembling that of the liver. This condition is most commonly associated with the consolidation phase of pneumonia, particularly lobar pneumonia.
Usage Examples
- (The lung tissue had become firm and liver-like due to infection.)
- (The early phase of consolidation where the tissue is still reddish.)
- (A later phase where the tissue turns grayish.)
Advanced Usage
"Red hepatization": the initial stage of consolidation in lobar pneumonia, characterized by a reddish, granular appearance due to the presence of red blood cells and fibrin.
- The patient's chest X-ray showed signs of red hepatization in the affected lobe. (The lung was in an early stage of solidification.)
"Gray hepatization": the later stage of consolidation, where the lung appears grayish or yellowish due to the accumulation of leukocytes and the breakdown of red cells.
- Gray hepatization indicates a more advanced inflammatory response. (The tissue has become paler and more fibrous.)
Variants and Related Words
Hepatize (verb): the process of becoming liver-like in texture or appearance, typically referring to lung tissue.
- The infected lung began to hepatize within days of the onset of pneumonia. (The tissue started to solidify.)
Hepatization (noun): the state or condition of being hepatized.
Synonyms
Consolidation: the process of becoming solid, especially in lung tissue.
- Pulmonary consolidation is a broader term that includes hepatization as a specific type.
Induration: the hardening of tissue, though this term is less specific to lung tissue.

Additional Notes
- Context: Hepatization is a pathological term used almost exclusively in histology and clinical pathology. It is not used in everyday language. The term derives from the Greek (liver) and the suffix (process of becoming).
- Contrast: Unlike the liver, which is normally solid, hepatization is always abnormal and indicates severe inflammation or infection in the lung.
