From: PAX8 expression reliably distinguishes pancreatic well-differentiated neuroendocrine tumors from ileal and pulmonary well-differentiated neuroendocrine tumors and pancreatic acinar cell carcinoma

(a) Low-power image of well-differentiated pancreatic neuroendocrine tumor (H&E, × 200), with adjacent non-neoplastic pancreas. (b) 3+, strong PAX8 staining in well-differentiated pancreatic neuroendocrine tumor and adjacent islet cells ( × 200). (c) Well-differentiated pancreatic neuroendocrine tumor (H&E, × 400) demonstrating 3+, strong PAX8 nuclear staining (d; × 400). (e) Well-differentiated pancreatic neuroendocrine tumor showing 2+, strong PAX8 nuclear staining ( × 400). (f) Well-differentiated pancreatic neuroendocrine tumor showing 3+, weak PAX8 staining ( × 400).
