Rapidly growing Epstein-Barr virus-associated pulmonary lymphoma after heart transplantation.
There is strong evidence to show an association of Epstein-Barr virus (EBV) infection with the development of post-transplant lymphoproliferative disease. We report the rapid development of a malignant lymphoma in a heart transplant recipient, which occurred within less than eight weeks. The diagnosis of this malignant high grade B-cell lymphoma was established by open lung biopsy, and classified as centroblastic lymphoma of polymorphic subtype. Immunohistochemically, the lymphoma showed reactivity with the B-cell markers L-26 (CD20) and Ki-B5 and with the activation marker Ber-H2 (CD30). Furthermore, an expression of the bcl-2 oncoprotein was detected. Monoclonal JH gene rearrangement was demonstrated by polymerase chain reaction (PCR), indicating monoclonal proliferation of B-blasts. Although serum EBV immunoglobulin M (IgM) antibodies were negative, the association to an EBV infection could be demonstrated by EBV immunostaining pattern which revealed an expression of the latent membrane protein (LMP) of EBV in the atypical blasts. The results give clear evidence of an EBV association of this rapidly growing lymphoma developed after heart transplantation.
