    Abstract:
    Epstein-Barr virus (EBV) associated lymphoproliferative disease (LPD) are commonly derived from B-cells, however, it is becoming more and more apparently that EBV can also infect T-lymphocytes. Systemic EBV positive T-cell LPD of childhood is rare and characterized by an extremely aggressive course and poor prognosis. Here, we report a 22-year-old female of systemic EBV positive TLPD with acute EBV infection and review the clinical features of this disorder. A 22-year-old previously healthy female without immunocompromised status presented with persisting coach and fever resistant to conventional therapies. Physical examination showed hemorrhage and hepatosplenomegaly. Laboratory examinations revealed severe pancytopenia, disseminated intra-vascular coagulopathy (DIC), and anti-EBV-IgM positivity. Peripheral blood smears and bone marrow investigation identified a number of atypical lymphocytes. Flow cytometry (FCM) did not show any significant evidence of leukemia or lymphoma. The lymph node biopsy showed apparent infiltration of lymphocytes, which expressed CD2+, CD3+, CD7+ and TIA1+. There was no CD20+ or CD56+ cells. EBV early RNA (EBER) was positive. Cytogenetic analysis showed a normal karyotype. T-cell receptor (TCR) gene rearrangement revealed a polyclonal pattern. The patient received prednisolone and IVIG therapy with a transient good condition, and then died of multiorgan failure one week after diagnosis.
