Positive control for AID, LMP-1, EBER, and Egr-1 in the overexpression and normal expression. (a) Sporadic Burkitt lymphoma (sBL) [34], (b) MTX-LPD [35], (c) Age-LPD [36], and (d) oral squamous cell carcinoma (OSCC) were used as an aberrant positive control (strong intensity/overexpression) for AID, LMP-1, EBER, and Egr-1 (hematoxylin-eosin staining: HE, left panel; immunohistochemical staining: IHC, right panel) ((a)–(d) original magnification ×100). Reactive lymphoid hyperplasia (RLH) was used as normally positive control (moderate/normal expression) for (e) AID, (f) LMP-1, (g) EBER, and (h) Egr-1 ((e)–(h) original magnification ×100). (g) Germinal center B-cells were moderate/normal positive for EBER, and plasma cells were strongly positive for EBER (right panel).
