title: [IBL-type lymphadenopathy after infection of rubella virus].
abstract: A 52-year-old woman presented slight fever, diffuse papular skin rash and painful cervical lymph node swelling. Her lymph node swelling generally up to 3 cm in diameter, with petechiae on the lower legs and hepato-splenomegaly within a few weeks. ESR was 45 mm/h, Hb 10.0 g/dl, RBC 345 x 10(4)/microliter, WBC 22,600/microliter (atypical lymphocyte 47%), PLT 1.0 x 10(4)/microliter, GPT 91 U/L, gamma-globulin 34.3%, EBV-VCA x 2,560, EBNA x 20, and anti-rubella antibody x 512. The biopsied cervical lymph node showed histologic features of effacement of nodal architecture by an exuberant vascular proliferation accompanied with infiltration of the immunoblasts, and was diagnosed as immunoblastic lymphadenopathy (IBL)-type lymphadenopathy. The pulse therapy of methylprednisolone and high dose of gamma-globulin improved lymphadenopathy, thrombocytopenia and anemia. IBL-type lymphadenopathy after infection of rubella virus may be different from true IBL, but is important to discuss the pathogenesis of IBL.
