    macroglobulinemia occurring in old people, characterized by proliferation of cells resembling lymphocytes or plasma cells in the bone marrow, anemia, increased sedimentation rate, and hyperglobulinemia with a narrow peak in γ-globulin or β2-globulin at about 19 S units. The spleen, liver, or lymph nodes are often enlarged with frequent purpura or mucosal bleeding.

    Alternate names: hyperglobulinemic purpura, Waldenström purpura, Waldenström syndrome

  • Waldenström test
