Immunohistochemical reactivity for pancreatic polypeptide in the collected 12 cases of duodenal gangliocytic paraganglioma. Legend: Photomicrographs showing the results of immunohistochemical staining of pancreatic polypeptide (Panel A to L represents Case 1 to 12 of gangliocytic paraganglioma). In 11 of the 12 cases examined, epithelioid cells showed positive reactivity for pancreatic polypeptide (Panel A to L; immunohistochemistry; magnification: × 200, for each, scale bar represents 300 μm).
