Shown in Figure 1, the computerized tomography scans of the chest, abdomen, and pelvis demonstrated a well-defined enhancing pancreatic tail mass highly suggestive of insulinoma.
Low-grade pancreatic neuroendocrine tumor. (a) Low-power (20x) view shows a well-circumscribed nested pattern of the tumor cells within the eosinophilic stromal background with adjacent pancreatic parenchyma and (b) 100x view. (c) 400x exhibits uniform nuclei with "salt and pepper" chromatin. (d) 200x shows an immunohistochemical stain for Ki67, which demonstrated 1% reactivity, supporting a low-grade designation.

Pathology results showed a low-grade well-differentiated noninvasive pancreatic neuroendocrine tumor, 1.5 cm diameter in size with no invasion present and negative margins as depicted in Figure 2.
