Figure 4 Immunohistochemical and in-situ hybridization staining of post-transplant lymphoproliferative disorder, monomorphic type (extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue) arising in a sigmoid colon polyp. A: CD20, 100 ×/240 μm; B: B-cell lymphoma (BCL)-2, 100 ×/240 μm; C: CD10, 100 ×/240 μm; D: BCL-6, 100 ×/240 μm; E: CD5, 100 ×/240 μm; F: EBER-ISH (inset: Positive control), 100 ×/240 μm. The monotonous small-size lymphocytes stained positive for CD20 and B-cell lymphoma-2 and were negative for the rest of the stains.
