title: [Acute hemolysis in polycythemia vera].
abstract: The clinical course of fulminant haemolysis in a 54 year old patient with polycythaemia vera is described. Haemolysis was due to a complement-activating cold-autoantibody of the IgM class. A pathogenetic association between polycythaemia vera as a myeloproliferative disorder and autoimmune-haemolysis is discussed.
