case_images: Immunohistological examination of the tumor tissue revealed positivity for pan cytokeratin (PCK) and CK17, and negativity for CK20, cluster of differentiation (CD)3, CD20, chromogranin A and synaptophysin (Figs. 1 and 2).
case_images: Immunohistochemical staining of (A) nasopharyngeal carcinoma and (B-G) breast tumor. The two tissues were positive for (A and B) CK17. The breast tumor tissue exhibited negative staining for (C) CK20, (D) CD3, (E) CD20, (F) synaptophysin and (G) chromogranin A (magnification, x200). CK, cytokeratin; CD, cluster of differentiation.
