a: at low magnification the pancreatic tumour displayed a typical trabecular architecture; b: at higher power the typical neuroendocrine nuclear features characterised by dispersed chromatin are observed; c: Immunohistochemistry for Chromogranin was diffusely strongly positive; d: Immunohistochemistry for Ki-67 demonstrated a proliferative index of 2% (original magnifications a: 100×, b, c, d: 400×; Case 2).
