title: Late relapse of myelodysplasia after allogeneic transplantation concomitant with new presentation of invasive liposarcoma as a secondary neoplasm.
abstract: Second malignancies are uncommon events in the survivors of allogeneic transplant procedures, although they are increased compared to normal control populations. Among these malignancies, sarcomas are exceedingly rare. In addition, relapse of primary myelodysplasia rarely occurs after 5 years from the time of allogeneic transplantation. This report describes an unusual presentation of liposarcoma with concomitant relapse of underlying myelodysplasia developing in a patient 9 years after the first of two allogeneic transplantations.
