Figure 3
Histological findings of the surgical specimen. Magnification: (a, c–f) ×20, HE, (b) ×40. (a) An epithelioid tumor cell has well-developed staghorn-like (hemangiopericytoma-like) vasculature. (b) Pleomorphic multivacuolated lipoblasts are occasionally found. (c) Sudan III stain demonstrates fat droplets in the cytoplasm. (d) CAM 5.2 is focally expressed in epithelioid tumor cells. (e) The tumor nuclei are diffusely positive for GATA3. (f) S100 proteins are focally expressed in lipogenic tumor cells.
