Figure 6

Pathological images. Infiltration of atypical, large lymphoid cells is seen in the endoscopic biopsy specimens (a): Hematoxylin-eosin stain. Lymphoma cells are positive for CD20 (b) and BCL2 (c), while they are negative for CD3 (d), CD5 (e), CD10 (f), and cMYC (g). The cells are diffusely positive for Ki-67 (h). The results of in situ hybridization for Epstein–Barr virus-encoded small RNA-1 (EBER) are also positive (i).
