Asymptomatic and Biochemically Silent Pheochromocytoma with Characteristic Findings on Imaging

Figure 3

Histology demonstrates the well-circumscribed nature of the typical pheochromocytoma. There is an abrupt and distinct border between the pheochromocytoma on the left and the surrounding normal adrenal gland on the right. The tumor has the typical low-power architecture with cells arranged in nests and cords.
