Immunohistochemical staining of CD3 and CD20 revealed that Epstein-Barr infection was mainly restricted to T lymphocytes in bladders showing interstitial cystitis/bladder pain syndrome.
Immunohistochemistry revealed that cyclin D1, CD5, and CD20 were expressed in the MCL but lost in the DLBCL cells, and EBER-ISH confirmed that EBV infection was absent in the former but present in the latter.
