Autoimmune hemolytic anemia with concurrence of warm and cold red cell autoantibodies and a warm hemolysin

Abstract
The laboratory findings and clinical course of a patient with thrombophlebitis, venous gangrene and autoimmune hemolytic anemia are described. Three concomitant red cell autoantibody activities were detected: a low-titer, high-thermal-amplitude, IgM anti-I cold agglutinin; an IgG warm incomplete panagglutinating autoantibody; an an IgM warm hemolysin.
