In general, the recipient's ABO blood type changes to the donor's ABO blood type after ABO-incompatible allogeneic hematopoietic stem cell transplantation (HSCT). However, we experienced a 26-year-old male with acute myelogenous leukemia (AML) who underwent ABO-incompatible HSCT twice and persistently showed his original blood type even after demonstrating complete donor-type chimerism. Based on the results of various examinations, we considered that the antigen of the recipient's original blood type persistently synthesized in the recipient's non-hematopoietic organs was secreted and adsorbed on the surface of donor-derived RBCs. We should therefore perform detailed examinations to determine the precise blood type after ABO-incompatible HSCT.
