Intestinal metaplasia of the stomach is a relative common finding that is associated with a modest increased risk of gastric carcinoma.

It is also known as gastric intestinal metaplasia and may be abbreviated IM.

General

Often part of surgical pathology report, e.g. "negative for intestinal metaplasia" or "intestinal metaplasia present".
May be associated with Helicobacter spp. infection -- though Helicobacter don't like intestinal type mucosa, i.e. H. pylori are not typically found in regions with intestinal metaplasia.
May be reversible - some epidemiological evidence.^[1]
Associated with gastric carcinomas of Lynch syndrome;^[2] however, surveillance may not be worthwhile.^[3]

Significance:

Moderate risk increase for carcinoma; risk less than for Barrett's esophagus.^[4]
- Odds ratio for corpus (~5.8x) higher than antrum (2.3x) when compared to individuals without IM.^[5]

Gross/endoscopic

+/-Erythema.
- Often associated with chronic gastritis.

Microscopic

Features:

Goblet cells are present in the stomach - key feature.^[6]
- In H&E sections the vacuole often stains light grey.
- Foveolar epithelium should be present in the same fragment.
+/-Paneth cells - deep in the glands.^[7]
- Very rarely present.
- Very uncommon in isolation.

Notes:

Intestinal metaplasia (IM) is occasionally subdivided:^[8]
- Complete IM = goblet cells and (intestinal) brush border.
- Incomplete IM = mucus vacuoles of various sizes, no (intestinal) brush border.
Goblet cells metaplasia starts in the neck region of the gastric glands.^[9]

DDx:

Normal small bowel mucosa - no foveolar epithelium present, possibly a contaminant from a concurrent duodenal biopsy.
Gastric dysplasia, intestinal type.
Gastric heterotopia of the duodenum.

Images

Stomach IM - intermed. mag. (WC)
Stomach IM - high mag. (WC)

Stains

Alcian blue (pH 2.5)/PAS +ve.^[10]
- May be used to divide into complete (type I) and incomplete (type II).^[11]^[12]
Alican blue stain +ve.^{[citation needed]}

Image

Barrett's mucosa - Alcian blue stain. (WC)

IHC

CDX2 +ve (-ve in normal stomach).^[1]
- Strong assoc. with Helicobacter gastritis as well as IM.^[13]

Others:

Lysozyme +ve - marks paneth cells.^[7]

  moderate chronic inactive inflammation.
- NEGATIVE for Helicobacter-like organisms.
- NEGATIVE for dysplasia and NEGATIVE for malignancy.
