Pancreatic neuroendocrine tumor detected by technetium-99m methoxy-2-isobutylisonitrile single photon emission computed tomography/computed tomography: A case report

Figure 4 Hematoxylin and eosin staining. A: The pathology of the focal radioactive concentration of the pancreatic body and tail shown on technetium-99m methoxy-2-isobutylisonitrile single photon emission computed tomography (CT)/CT indicated a well-differentiated pancreatic neuroendocrine tumor via hematoxylin and eosin staining (× 200); B: The pathology of the upper abdominal mass shown on CT indicated a well-differentiated pancreatic neuroendocrine tumor via hematoxylin and eosin staining (× 200); C: Normal spleen cells observed after hematoxylin and eosin stain (× 100).
