title: B-immunoblastic lymphoma arising in angioimmunoblastic lymphadenopathy.
abstract: We present a female patient with a B-immunoblastic lymphoma of the IgM-lambda type arising in angioimmunoblastic lymphadenopathy. An increased ratio of helper/inducer to suppressor/cytotoxic lymphocytes in the lymph node could have triggered the proliferation of B cells. Evolution of IgM cryoglobulinemia was paralleled by malignant transformation in the lymph node. A short-term in vitro chemosensitivity test could predict response to COP combination chemotherapy suggesting that in vitro chemosensitivity testing can be useful for the therapeutic management of angioimmunoblastic lymphadenopathy.
