Figure 2: (a) (Haematoxylin and eosin [H and E] ×100) Tumour arranged in fascicles and whorls with cells showing round nuclei, indistinct cell borders, and few psammoma bodies. The majority of the neoplastic cells exhibit a prominent xanthomatous appearance. No mitotic activity was noted. (b) Higher magnification shows xanthomatous areas with tumor cells having clear vacuolated cytoplasm and bland round to oval nuclei. (c) Higher magnification demonstrating areas of whorl formation and psammomatous bodies. (d) On immunohistochemistry, EMA was positive for both xanthomatous and non-xanthomatous cells. (e) CD68 was positive only in xanthomatous cells
