Paroxysmal cold haemoglobinuria caused by non-Hodgkin's lymphoma.

Paroxysmal cold haemoglobinuria is an autoimmune haemolytic anaemia characterized by a biphasic polyclonal IgG autoantibody, the Donath-Landsteiner (D-L) antibody. Although classically described in association with chronic syphilis, it is most commonly seen after acute viral infections in children. We describe a case of high-grade B-cell non-Hodgkin's lymphoma which presented with paroxysmal cold haemoglobinuria. The lymphoma responded promptly to combination chemotherapy whilst, at the same time, the haemolytic process rapidly resolved. Subsequent investigations showed that the D-L antibody originated from the lymphoma cells.
