Photomicrographs showing different types of tumor cells. (A) Tumor cells of epithelioid cell type are usually nested which are encompassed by those of spindle-shaped cell type with alignment of a single cell layer (HE double stain, × 400). (B) Ganglion-like cells; third type of the tumor cell had a large and oval nucleus with conspicuous nucleolus, as well as a polyhedral amphophilic cytoplasm (HE double stain, × 1000). (C and D) The metastasizing component of the tumor at the lymph node comprised the epithelioid cell type alone (HE double stain, × 100, × 400, respectively).
