A Case of T/NK-Cell Post-Transplantation Lymphoproliferative Disease 7 Years after Heart Transplantation.

Post-transplant lymphoproliferative diseases (PTLD) are potentially fatal complications after cardiac transplantation. Most cases are Epstein-Barr virus (EBV)-related B-cell tumors, and reduction of immunosuppression treatment as well as the use of rituximab in combination with other chemotherapy are effective. However, patients with T/NK-cell PTLD post-cardiac transplantation are rarely reported. We had a patient with a fever that lasted for three weeks, with lung infiltrations and hepatosplenomegaly, who had EBV-associated hemophagocytosis 7 years after heart transplantation and was eventually diagnosed with T/NK-cell PTLD by autopsy. Although rare diseases, regular monitoring of EBV-DNA levels might be crucial for early diagnosis and treatment of PTLD.
