Donor Derived Cell Leukemia (DCL) is a rare complication of Hematopoietic Stem Cell Transplantation (HSCT).DCL represents a unique form of leukemogenesis in which donor cells become transformed or proliferate followingengraftment in a foreign host environment. We report a 58-year old patient with B-cell acute Lymphocytic leukemia whounderwent an allergenic HSCT from his Human Leukocyte Antigens (HLA)-matched sibling. Three months after HSCT,chromosomal analysis revealed a female karyotype with a (9;22) translocation. This was confirmed with Fluorescencein Situ Hybridization and polymerase chain reaction studies in the recipient and the donor confirming the transmissionof occult leukemia.
