title: Lymphoproliferative disease with IgM lambda monoclonal protein and autoimmune hemolytic anemia. A report of four cases and a review of the literature.
abstract: Four patients with lymphoproliferative disease with immunoglobulin M lambda (IgMlambda) monoclonal proteins and severe autoimmune hemolytic anemia are described. These patients had many features in common that may warrant their recognition as a specific entity within the lymphoproliferative spectrum. In each case, a wide thermal range low titer cold agglutinin was present. The association of cold autoimmune hemolytic anemia with IgMlambda monoclonal protein and lymphoproliferative disease is unusual. The literature on IgM monoclonal proteins associated with lymphoproliferative disease is reviewed with emphasis on the presence of direct antiglobulin test positive autoimmune hemolytic anemia.
