Figure 3: The gross pictures of right renal mass (a) and left adrenal mass (b). (c) The right renal mass showed compact tumor cells with clear cytoplasm and thin-walled vasculature that were immunoreactive for epithelial membrane antigen (EMA), CD10, and vimentin (×50), indicating clear cell renal cell carcinoma (H and E, ×100). (d) The left adrenal mass showed trabecular or solid patterns of polygonal shaped cells with vacuolated cytoplasm that were immunoreactive for S100 and chromogranin-A (×50), indicating pheochromocytoma (H and E, ×100)
