title: Blood group change in acute myeloid leukemia.
abstract: Blood group antigens are either sugars or proteins found attached to the red blood cell membrane. ABO blood group antigens are the most clinically important antigens because they are the most immunogenic. As red blood cell antigens are inherited traits, they are usually not altered throughout the life of an individual. There have been occasional case reports of ABO blood group antigen change in malignant conditions. We report two such cases of ABO antigen alteration associated with acute myeloid leukemia. These patients had suppression of their blood group antigens during their leukemic phase, and the antigens were reexpressed when the patients attained remission.
