===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.)
