Peptic duodenitis is controversial type of chronic duodenitis. This article deals with that controversy and foveolar metaplasia of the duodenum.

General

  • A somewhat controversial type of chronic duodenitis.
  • Considered to be a consequence of peptic ulcer disease (Helicobacter gastritis).
  • One of the key components of the diagnosis is foveolar metaplasia and it is disputed that this is really due to Helicobacter.
    • Genta et al. consider gastric foveolar metaplasia a congenital lesion.[1]

Chronic duodenitis

- Small bowel mucosa with Brunner’s gland in the lamina propria and gastric foveolar metaplasia, consistent with chronic duodenitis.
- NEGATIVE for acute duodenitis.
- NEGATIVE for dysplasia and NEGATIVE for malignancy.

Micro

The sections show small bowel mucosa and a small amount of submucosa. Brunner's glands are abundant and found focally in the lamina propria. Gastric foveolar-type epithelium is identified. Intraepithelial neutrophils are not identified.

The epithelium matures appropriately. There is no increase in intraepithelial lymphocytes.
