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. - NEGATIVE FOR ACTIVE INFLAMMATION. - NEGATIVE FOR DYSPLASIA AND NEGATIVE FOR MALIGNANCY. 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.
