Bleeding Meckel’s Diverticulum in a 33-Year-Old Female Diagnosed with Video Capsule Endoscopy and a Technetium-99 m Pertechnetate Scan with a Favorable Response to H₂ Blocker and PPI

Pathology report of the resected tissue.

Macroscopic findings	We received a partially longitudinally resected segment of the small intestine with a total length of 5 cm, perimeter of 3.5 cm, and mural width of 0.4–0.8 cm. The contour of the small intestinal mucosa is regular, while in a zone of approximately 2.2 × 2 cm contralateral to the mesentery, there is a semicircular widening of the lumen, a diverticulum, with thinning of the wall to 0.4–0.5 cm, and flattened and hyperaemic mucosa. The width of the wall in the remaining part is 0.6–0.8 cm
Microscopic findings	In part, the structure of the small intestinal wall has a regular histologic architecture, with scant chronic inflammatory infiltrate in lamina propria, while in part, the lumen is covered by gastric mucosa with a moderate and, in some places, accentuated chronic inflammatory infiltrate in lamina propria with the presence of many eosinophils and multifocal mucinous metaplasia. There are small foci of cystic glandular dilation and an atrophic appearance of the mucosa. Parietal cells with a deeply eosinophilic cytoplasm are detected. In places, the inflammatory infiltrate spreads to the submucosa, where it has a much lesser intensity. In the part of the diverticular widening, there is thinning of the muscle layer of the wall of the diverticulum
Conclusion	The findings correlate with Meckel’s diverticulum with gastric mucosa and signs of chronically active inflammation. The resection margin shows regular small intestinal structure except for the presence of a discrete inflammatory infiltrate in lamina propria
