 DUODENUM, BIOPSY:
- MODERATE NON-SPECIFIC CHRONIC DUODENTIS (SMALL BOWEL MUCOSA WITH VILLOUS
  BLUNTING, PROMINENT BRUNNER'S GLANDS, ABUNDANT LAMINA PROPRIA PLASMA CELLS
  AND OCCASIONAL INTRAEPITHELIAL LYMPHOCYTES, WITHOUT FOVEOLAR METAPLASIA).
- NEGATIVE FOR DYSPLASIA.
DUODENUM (POLYP), BIOPSY:
- FRAGMENTS OF SMALL BOWEL MUCOSA WITH FOCAL GASTRIC FOVEOLAR METAPLASIA WITH
  ABUNDANT PLASMA CELLS AND REACTIVE CHANGES.
- PROMINENT BRUNNER'S GLANDS.

COMMENT:
The classic teaching is that foveolar metaplasia is associated with a Helicobacter
infection, which may be found only in the stomach; however, there is some evidence to
suggest that foveolar metaplasia may represent a congenital lesion. [1]
