Enteroscopy confirmed the presence of numerous polyps, ranging from 4 to 15 mm in size, along the greater curvature of the gastric body (Figure 1), as well as throughout the entire duodenum and in the proximal jejunum (beyond the ligament of Treitz) (Figure 2).

Biopsies of the polypoid duodenal mucosa and endoscopic mucosal resection (EMR) of the proximal jejunum (Figure 3) revealed focally increased chronic as well as acute inflammation with pseudopolyp formation, evidence of reactive lymphoid hyperplasia in the lamina propria, focal cryptitis, and villous blunting and epithelial regenerative changes (Figures 4 and 5).
Haematoxylin and eosin (H&E) stain of small bowel tissue sample at low power (100x magnification) demonstrating expansion of the lamina propria by moderately increased chronic inflammation and reactive lymphoid hyperplasia with focal cryptitis, villous blunting, and epithelial regenerative changes consistent with inflammatory pseudopolyps.

Haematoxylin and eosin (H&E) stain of small bowel tissue sample at high power (400x magnification) demonstrating acute focal cryptitis evidenced by neutrophils within the glandular architecture (arrow), and expansion of the lamina propria by a diffuse neutrophilic infiltrate.
