  Fig. 5. Pathological examination A: Proliferation of large oncocytic tumor cells exhibiting a solid architecture (Hematoxylin and Eosin, magnification ×100). B: The tumor cells are polyhedral in shape, displaying abundant granular eosinophilic cytoplasm. The nuclei are vesicular, varying in size, and highly nucleolated. Some of the tumor cells are multinucleated (arrows). No mitotic figures are observed (Hematoxylin-Eosin, magnification ×250).
