T-cell markers other than CD5 (CD8, CD7, CD2, and CD4) were found in 27/501 (5%) cases, all of which were histologically categorized as large B-cell lymphomas: 25 DLBCL, including one case accompanied by FL grade 3B, and 2 IVLBCL cases (Figure 1 and Table 2). Here, CD4 is linked to diffuse large B-cell lymphoma.
