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]

PHG. (WC/Samir)
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.
Sign out
STOMACH, BIOPSY: - ANTRAL-TYPE AND BODY-TYPE GASTRIC MUCOSA WITH PROMINENT CAPILLARIES AND MODERATE CHRONIC INACTIVE INFLAMMATION. - NEGATIVE FOR HELICOBACTER-LIKE ORGANISMS. - NEGATIVE FOR INTESTINAL METAPLASIA. - NEGATIVE FOR DYSPLASIA AND NEGATIVE FOR MALIGNANCY. COMMENT: No fibrin thrombi are seen. The findings are compatible with portal hypertension. Clinical correlation is required.
Hyperplastic-like polyp
POLYP, STOMACH, BIOPSY: - HYPERPLASTIC-LIKE POLYP WITH PROMINENT VESSELS, EDEMA AND AN ERODED SURFACE WITH GRANULATION TISSUE FORMATION, SEE COMMENT. - NEGATIVE FOR HELICOBACTER-LIKE ORGANISMS. - NEGATIVE FOR INTESTINAL METAPLASIA. - NEGATIVE FOR DYSPLASIA AND NEGATIVE FOR MALIGNANCY. COMMENT: The polyp is consistent with the type described by Lam et al. in a set of individuals with portal hypertension. (Eur J Gastroenterol Hepatol 23 (12): 1245-9.)
