Magnifying Endoscopic Features of Follicular Lymphoma Involving the Stomach: A Report of Two Cases

Figure 4

Histological images of stomach tissue biopsies from case 2. Dense, diffuse infiltration of small- to medium-sized lymphoma cells was observed, in addition to the existence of granulation tissues, with preserved epithelial cells, from biopsy samples taken from the gastric mucosa where intact pits were observed (hematoxylin and eosin staining, (a) ×20, (b) ×40). An image from biopsy samples taken from where damaged gastric pits were observed shows lymphoma infiltration, but with loss of epithelial cells ((c), hematoxylin and eosin staining, ×20). Neoplastic lymphoid follicles are shown (arrows). Lymphoma cells were positive for CD20 ((d), ×20), CD10 ((e), ×20), and BCL2 ((f), ×20) and negative for CD3 ((g), ×20).
