MYELOID-LEUKEMIA AND MYELODYSPLASTIC SYNDROME RELAPSING AS GRANULOCYTIC SARCOMA (CHLOROMA) AFTER ALLOGENEIC BONE-MARROW TRANSPLANTATION

Of 229 consecutive patients receiving allogeneic blood or bone marrow stem cell transplants for acute myeloid leukemia, chronic myeloid leuk emia, or myelodysplastic syndrome between 1974 and 1996, 52 patients r elapsed. The original tumor recurred as granulocytic sarcoma (chloroma ) in three patients (1.3%). Chloroma was found in the ovary in two pat ients and in the central nervous system in one patient. None of these three patients had experienced greater than or equal to grade II acute or more than limited chronic graft-versus-host disease. The intervals between transplantation and recurrence with chloroma were 2, 6, and 1 3 years. Two patients received a second transplant, and all three died of treatment sequelae.
