Figure 4: (a-d) Photomicrograph showing metastatic deposits of undifferentiated nasopharyngeal carcinoma in thyroid with interspersed lymphoid cells (a and b; H and E, ×100 and × 200). The tumor cells were immunopositive for high molecular weight cytokeratin (c; DAB: ×100) and revealed moderate-to-strong diffuse nuclear positivity for Epstein-Barr-encoded RNA/in situ hybridization (d; DAB; ×100).
