Heterotopic pancreatic components. The haematoxylin and eosin micrograph showed exocrine and endocrine structures of pancreas (a, original magnification ×10). Ducts and pancreatic acini were highlighted by pan-cytokeratin marker AE1/3 immunostaining (b, ×10) and Periodic acid–Schiff–diastase special stain (c, ×10) respectively. The distribution of insulin-, glucagon-, and somatostatin-producing neuroendocrine cells scattered in the islets were demonstrated with respective immunohistochemistry (d to f, ×10)
