Based on identifying one case of strongly stainable Trop2-positive EBV-positive DLBCL (Figure 2 and Figure 3) that emerged from AITL, next, we performed an additional systemic search in the pathology reports database to identify all cases of EBV-positive DLBCL that emerged from AITL. Here, TACSTD2 is linked to angioimmunoblastic T-cell lymphoma.
