Figure 5

Section showing nodular proliferation of chief cells and oxyphilic cells. The component cells show a palisaded arrangement around blood vessels. (a) Low power. (b) Medium power. (c) High power (H&E, ×20): oxyphilic cells show round-to-ovoid nuclei with abundant granular eosinophilic cytoplasm. (d) Chief cells (H&E, ×20): chief cells show round nuclei and amphophilic cytoplasm. No nuclear pleomorphism or increased mitotic activity is seen.
