BACKGROUND: Transfusion of cells harvested from patients with chronic myelogenous leukemia (CML) as a therapeutic measure for patients with granulocytopenia was popular in the 1970s, when studies examining the persistence of transfused donor cells were limited by a lack of molecular techniques. Blood samples from a patient who recently received an inadvertent transfusion of CML cells were evaluated for the presence of the bcr/abl translocation characteristic of CML. CASE REPORT: The patient, a 67‐year‐old man with a history of congestive heart failure, myocardial infarct, hypertension, diabetes mellitus, and chronic renal failure, was transfused for bleeding from colonic angiodysplasia. A volunteer blood donor reported that he had been diagnosed with CML 10 days after his donation. Three days after the donation, blood components from the donor with CML had been administered to the patient as nonirradiated red cells and platelets. Evaluation of donor blood by a reverse‐transcriptase polymerase chain reaction showed the b3a2 transcript, indicating a bcr/abl translocation. Periodic testing of the patient's peripheral blood by the same technique demonstrated the presence of the b3a2 transcript on Days 74 and 75 after transfusion. The patient died of congestive heart failure 8 months after the transfusion. CONCLUSION: In this rare case of accidental transfusion of neoplastic cells, the findings document the persistence of the donor's neoplastic clone in the recipient for 75 days.
