Figure 3

Pathological photomicrographs demonstrated that the mucosa was intact and expanded by a diffuse infiltrate of lymphoma cells (a, H&E). The mucosal lymphoid infiltrate was destructive, resulting in necrosis. The medium-to-large transformed cell nuclei had an irregular nuclear folding with granular appearance (b, H&E). Positive immunohistochemical staining was recorded for (c) CD56, (d) CD3, (e) LCA, (f) CD38, and (g) EBER in situ hybridization (original magnification: ×200).
