Clinicopathologic features of surgically resected primary gastric lymphoma

Figure 1 A: Low grade MALT lymphoma. Microphotograph showing proliferation of heterogeneous small B-cells, includ-ing marginal zone (centrocyte-like) cells, cells resembling monocytoid cells, small lymphocytes, and scattered immunoblast and centroblast-like cells. In epithelial tissue, neo-plastic cells typically infiltrated the epithelium, forming lymphoepithelial lesions. B: Diffuse large B cell lymphoma. Microphotograph showing proliferation of large B lymphoid cells in a diffuse pattern. Tumor cells have a large and pleo-morphic appearance with prominent nucleoli.
