Intestinal intussusception caused by intestinal duplication and ectopic pancreas: A case report and review of literature

Figure 1 Postoperative gross specimen showing intestinal duplication (yellow arrow) and adipose tissue hyperplasia with ectopic pancreatic tissue (red arrow).

Figure 2 Hematoxylin & eosin staining. A: Microscopic view of the wall of the normal intestine (red arrow) and duplicated intestine (yellow arrow) [hematoxylin & eosin (HE) × 5]; B: Microscopic view of adipose tissue hyperplasia on the serosa surface of the duplicated intestinal wall (yellow arrow) with ectopic pancreas (red arrow) (HE × 5); C: Microscopically, the ectopic pancreatic tissue showed pancreatic islet cells (yellow arrow), pancreatic acinus (white arrow), and the pancreatic duct (red arrow) (HE × 200).
