Hyperplastic polyp

 • Common polyp which occurs mostly in the antrum or body.

 • Non- neoplastic reactive lesion thought to represent an exaggerated regenerative response to mucosal injury.

 • Often associated with an underlying gastric pathology such as Helicobacter or autoimmune gastritis.

 • histology shows a polyp containing a dilated, elongated, tortuous foveolar epithelium in an oedematous, inflamed lamina propria.

Fundic gland polyp

 • Common polyp which occurs only in the body or fundus.

 • Most frequently seen in patients taking proton pump inhibitors. Can occur sporadically or in association with familial adenomatous polyposis (FAP).

 • FAP- associated polyps are more likely to be multiple and occur at a younger age.

• Sporadic polyps are not normally associated with any underlying mucosal pathology.

 • histology shows a polyp containing cystically dilated fundic glands lined by flattened parietal and chief cells.

 Gastric adenoma

 • Uncommon neoplastic polyp that can occur throughout the stomach.

 • Microscopically composed of dysplastic glands with stratified hyperchromatic nuclei.

 • two main types are described— an intestinal and a foveolar type.

• Intestinal types are far more likely to show high- grade dysplasia or harbour gastric carcinoma than the foveolar type.

 Gastric xanthoma

 • Uncommon polyp that occurs anywhere in the stomach.

 • Appears as a pale- yellow nodule due to its lipid content.

 • histology shows numerous lipid- laden macrophages in the lamina propria.

Inflammatory fibroid polyp

 • rare lesion which occurs mostly in the antrum.

 • histology shows a submucosal lesion composed of bland spindle cells arranged around prominent vessels, all set in a loose myxoid stroma containing conspicuous eosinophils.
