Fig. 5. (A) Strong granular membranous and cytoplasmic expression of latent membrane protein-1 (LMP-1) in the lymphoepithelioma-like carcinoma (LELC) component. Note the negative expression in the surrounding infiltrating lymphocytes and benign bile duct (LMP1; IHC, ×200). (B) Components of adenocarcinoma and LELC both showing strong cytoplasmic and membranous expression of latent membrane protein-1 (LMP1; IHC, ×40). (C) Positive nuclear expression of EBV encoded RNA on chromogenic in situ hybridization (EBER CISH, ×200).
