Nuclear staining for EBER by in situ hybridization in infiltrative ductal carcisnoma of the breast and control tissues. a. Normal duct staining for H&E. b. Normal duct negative for Epstein –Barr Virus by ISH for EBER. c. Infiltrative ductal carcinoma with individual cells in the stroma. d. Infiltrative ductal carcinoma of the breast, malignant cells showing positive Epstein-Barr virus by EBER. Positive signals are seen in the nuclei of tumor cells, but not in adjacent lymphocytes and normal cell. e. Invasive lobular carcinoma. f. EBV positive signal in tumour cells nucloi.
