The First Case of Concomitant Lymphadenitis and EBV-Positive Lymphoproliferative Disorder.

This is the first case of concurrent lymphadenitis and Epstein-Barr virus (EBV)-positive lymphoproliferative disorder (LPD) in the same lymph node with no immunocompromised history. infection is a rare opportunistic infection mainly for human immunodeficiency virus (HIV)-infected patients. Although no immunodeficiency was detected in our patient, our case indicates that the immunodeficiency in the background of EBV latency type III and the immunosuppression by malignant lymphoma itself might induce the lymphadenitis. This case highly alerts clinicians to the immunosuppressive state of EBV-positive LPD with latency type III even if any immunodeficient serological factors are not detected.
