Fig. 2.
Intestinal T-NHL. (A) T-NHL, non-EATCL type. The vast majority of the neoplastic cells show strong expression of EBERs. Crypts are largely spared by the tumor cells. Case no. 1, original magnification ×400. (B) T-NHL, EATCL-like. Occasional large cells clearly identifiable as neoplastic show strong EBER expression. Case no. 7, original magnification ×1000. (C) T-NHL, non-EATCL type. A single small bystander cell (arrow) shows coexpression of EBERs and CD20 (L26). Some neoplastic large T cells lacking CD20 expression are positive for EBERs. Double staining for L26 (brown) and EBERs (black). Case no. 8, original magnification ×1000.
