(A) Immunohistochemistry revealed a large number of atypical lymphoid cells expressing CD2 (A: 20X10), CD3 (B: 20X10), CD4(C: 20X10) and CD7 (E: 20X10). CD5 (D: 20X10)-positive cells were less than CD3-positive cells; CD8 (F: 20X10)-positive cells were less than CD4-positive cells and CD20 (G: 20X10)-positive cells presented a focal distribution. Granzyme B (H: 20X10)-positive cells were scattered. There was partial positivity for TIAI (J: 20X10), TCRGβ, and TCRγδ. Cells were negative for CD56 and Ki-67 (I: 20X10)-positivity was 40–50%. (B) EBV in situ hybridization for EBV encoded mi-RNA (EBER) demonstrated EBV-positive (50/HPF) atypical lymphoid cells (K: 20X10).
