Figure 2: Hematoxylin and eosin stained sections show the well-circumscribed nodule in the submucosa (a) composed of tumor cells in nests separated by thin vascular septae and cells having characteristic central nuclei with stippled chromatin (b). These tumor cells are positive for neuron-specific enolase (c) and synaptophysin (d), while being negative for chromogranin (e)
