Villous appearing duodenal mass of ampulla, secondary to ampullary duct obstruction. 43 yo White man. A. Plicae show expansion of stroma by edema with inflammation including neutrophils (neutrophils not shown), by foci of lamina propria hemorrhage (red arrows), and by dilated lymphatics (black arrows).  B. A fragment shows dilated ducts on left and center, with connected “proliferating” ducts at right. C. PAS AB stain shows these ducts, by virtue of the thin red line, are ampullary, not Brunner’s glands. D. Nuclei in the proliferated area show striking anisokaryosis and anisonucleosis, as well as hyperchromasia. Note the mitosis (arrow).  This notwithstainging, there is an appearance of connection between the ducts. No net appears. Neither are there half glands or aberrant isolated cells.  E. On PAS AB stain lay a focus of fibrinopurulent exudate near the proliferating area.
