Figure 1
(a) Gross photograph of resected adrenal mass. (b) Low power photomicrograph of adrenocortical tumor. The tumor is encapsulated (arrow) and has a pushing border, with compressed normal adrenal cortex on the right. (H&E, 20x). (c) High power photomicrograph of adrenocortical tumor. Arrow is pointing to a thin fibrous capsule. The tumor has similar cytologic features to the normal adrenal seen on the right. Features that have been associated with malignancy (capsular invasion, necrosis, and increased mitotic activity) are not present (H&E, 200x).
