title: Plasmacytic hyperplasia--the early form of posttransplant lymphoproliferative disorder--with atypical morphology and clinical course in patient after liver transplantation: a case report.
abstract: This case report describes an early lesion of posttransplant lymphoproliferative disorder (PLTD)--plasmacytic hyperplasia with atypical morphology. The 54-year-old patient was 4 months after liver transplantation due to alcoholic cirrhosis. The postoperative course had been uneventful without graft rejection episodes. Primary immunosuppressive therapy included tacrolimus and prednisone. On admission to the hospital the patient showed rapidly increasing jaundice, hepatomegaly, anemia, thrombocytopenia, and significant leukocytosis. A biopsy suggested generalized infection. Acute Epstein-Barr virus (EBV) infection was confirmed using serological methods. Despite treatment the patient died. On autopsy we found features of generalized infection. Histological examination of the enlarged lymph nodes showed plasmacytic hyperplasia despite lymph node atrophy. Plasmacytic hyperplasia, an early lesion of PTLD despite usually a good prognosis with multifactor therapy may display a rapid course that leads to death through intensified immunosuppression. In accordance with other reports we confirmed reactivation of EBV infection as the probable cause of plasmacytic hyperplasia. The lymph node morphology of plasmacytic hyperplasia may be atypical with atrophy of lymphoid components accompanying plasma cell proliferation.
