In situ hybridization with EBER probes. In a representative lymphadenopathy case (no. 20), rare EBER⁺ cells are seen, mainly in the interfollicular areas (A and B). In a representative lymphoma case (no. 46) nearly half of the cells are EBER⁺ (C and D). Original magnification: ×130 (A and C) and ×260 (B and D).
