===General===
{{Main|Portal hypertensive gastropathy}}
*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.<ref name=pmid15648238>{{Cite journal  | last1 = Mesihovic | first1 = R. | last2 = Prohic | first2 = D. | last3 = Gribajcevic | first3 = M. | last4 = Vanis | first4 = N. | last5 = Gornjakovic | first5 = S. | last6 = Sarac | first6 = A. | title = Portal hypertensive gastropathy (PHG). | journal = Med Arh | volume = 58 | issue = 6 | pages = 377-9 | month =  | year = 2004 | doi =  | PMID = 15648238 }}

===Microscopic===
Features:<ref name=Ref_GLP120-1>{{Ref GLP|120-1}}</ref>
*Dilated capillaries in the submucosa (prominent) and to a lesser extent in the lamina propria - '''key feature'''.
 
Notes:
*May be associated with [[hyperplastic polyp of the stomach|hyperplastic]]-like polyps.<ref name=pmid22002002>{{Cite journal  | last1 = Lam | first1 = MC. | last2 = Tha | first2 = S. | last3 = Owen | first3 = D. | last4 = Haque | first4 = M. | last5 = Chatur | first5 = N. | last6 = Gray | first6 = JR. | last7 = Yoshida | first7 = EM. | title = Gastric polyps in patients with portal hypertension. | journal = Eur J Gastroenterol Hepatol | volume = 23 | issue = 12 | pages = 1245-9 | month = Nov | year = 2011 | doi = 10.1097/MEG.0b013e32834c15cf | PMID = 22002002 }}</ref>
**Subepithelial [[granulation tissue]] and vascular proliferation.
*Findings in mucosal biopsies are often [[specificity|nonspecific]], i.e. not diagnostic.<ref name=Ref_GLP120-1>{{Ref GLP|120-1}}</ref>
 
DDx:
*[[Gastric antral vascular ectasia]] - have thrombi in the dilated blood vessels.
 
===Sign out===
<pre>
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.
</pre>
 
====Hyperplastic-like polyp====
<pre>
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.)
