(A) The tumor is composed of cells showing neuroendocrine features. (B) The tumor cells that show neuroendocrine features are positive for neuroendocrine markers (chromogranin). (C) Low-power magnification of pancreatic tissue shows an increased number of irregular-shaped hyperplastic islets scattered randomly in the pancreas. (D) Irregular-shaped islets in close approximation to pancreatic exocrine ductal structures (arrows). (E) The hyperplastic islets contain cells with enlarged hyperchromatic nuclei and of different sizes. (F) Approximately half of cells within the hyperplastic islets are stained with insulin.
