Gastric polyps
-Hyperplastic (inflammatory)
polyps (~75%)
exuberant response to
chronic gastritis
Hyperplastic mucosal
epithelium (Foveolar cells proliferation)
not a true neoplasm
inflamed
edematous stroma
hyperplasia is secondary to inflammation, that’s
why they are called inflammatory polyps
Adenomatous polyps (∼10%
They are true neoplasms.
combination of two processes
dysplastic,
hyperplastic epithelium
the higher the grade of dysplasia
the higher risk of malignant transformation
malignant transformation
increases with polyp size (>2cm)
-Fundic gland
polyps (∼10%)
do not have
neoplastic potential. (NOT truly neoplastic)
Small
collections of dilated corpus-type glands
occur
r due to excessive use of PPIs (Proton
pump inhibitors)
in persons with FAP
(familial adenomatous polyposis)
uncommon compared to other colonic and small intestinal
polyps
