lymphoproliferative syndrome induced

lymphoproliferative syndrome induced,

a group of malignant neoplasms associated with infections by human T-cell lymphotropic virus type I. The neoplasms arise from the clonal proliferation of lymphoid cells. They may originate in the bone marrow, as lymphoid leukemias, or in extramedullary sites, as lymphomas. The most common lymphoid leukemias include lymphoblastic leukemia, which can be rapidly fatal if untreated.
