Donor-derived myeloid sarcoma in two kidney transplant recipients from a single donor. In two cases donor origin of AML was assumed because of karyotype of blasts due to different gender of donor and recipient, but detailed genetic analyses were not available. A and C Giemsa, B and D CD71 immunoperoxidase gl The few previously published case reports suggest that donor-derived and donor-transmitted AML tends to occur several years (mean of 28 months) after SOT (Table S3).5-13 In six cases extramedullary manifestation was confirmed.
