Microscopic findings. a Jejunal duplication (hematoxylin–eosin staining, ×40). The jejunal duplication comprises intestinal mucosa, submucosa, muscular, and serosal layers. b Ectopic pancreatic tissue (hematoxylin–eosin staining, ×40). Ectopic pancreatic tissue with acini and ducts is observed in the adipose tissue between the muscular and serosal layers at the tip of the duplication. c Chronic pancreatitis (hematoxylin–eosin staining, ×40). Part of the ectopic pancreatic tissue exhibits chronic pancreatitis with the proliferation of fibroblasts and lymphocytic infiltration. d Hemorrhagic necrosis (hematoxylin–eosin staining, ×100). Hemorrhagic necrosis is observed in the serosa at the tip of the duplication, and pancreatic tissue is not detected
