Asymptomatic gastric adenomyoma and heterotopic pancreas in a patient with pancreatic cancer: A case report and review of the literature

Figure 5 Histology (HE, 40 × magnification). A: Disorganized pancreatic acini joining together and forming rough structures without islets and separated by bundles of smooth muscle (yellow arrow); the concomitant Brunner’s glands (blue arrow); and the undifferentiated mucus-secreting ducts, somewhat similar to gastric glands (white arrow); B: Typical gastric adenomyoma in another section of the gastric mass (yellow arrow) showing a mucus-secreting duct lined with columnar or cubic epithelial cells and surrounded by proliferating smooth muscle cells without heterotopic pancreas nearby.
