Pathological and immunohistochemical results of the proband. Legend: On hematoxylin and eosin stain, the tumor cells proliferated with a solid nest-like pattern, and were separated by slight fibrous vascular septum (a). The tumor cells show round to oval, hyperchromatic nuclei and the nucleoli of the tumor cells were inconspicuous, and there were a few mitotic figures (7~8/ 10HPF) (b). On immunohistochemical stain, the tumor cells were strong positive for CD56 (c), CgA (d) and Syn (e), and the Ki-67 proliferation index is estimated at 3% (f). The yellow arrow in B is mitotic figure
