Portal hypertensive gastropathy, abbreviated PHG, is a benign pathology of the stomach caused by high blood pressure in the portal system.
General
- Due to portal hypertension.
- Usually secondary to liver cirrhosis which is typically due to alcoholism.
- Reported in approximately 65% of cirrhotics with portal hypertension in one paper.[1]
- Usually secondary to liver cirrhosis which is typically due to alcoholism.
Gross
Features:[2]
- Mosaic-like pattern.
- May be referred to as snakeskin-like pattern.[3]
- Usu. body of stomach.
- +/-Red spots.
Note:
- May mimic eosinophilic gastritis.[3]

Microscopic
Features:[4]
- Dilated capillaries in the submucosa (prominent) and to a lesser extent in the lamina propria - key feature.
Notes:
- May be associated with hyperplastic-like polyps.[5]
- Subepithelial granulation tissue and vascular proliferation.
- Findings in mucosal biopsies are often nonspecific, i.e. not diagnostic.[4]
DDx:
- Gastric antral vascular ectasia - have thrombi in the dilated blood vessels.
