Chloroma is a tumour composed of immature granulocytes localized in extramedullary tissues. Chloroma is noted in the course of the acute non-lymphoblastic leukemia (ANLL), chronic myeloid leukemia (CML), and in myelodysplastic syndromes (MDS) during their transformation in the acute leukemias. Due to chloroma infrequency, two cases seen at the Department of Hematology, Medical Academy in Warsaw are presented. A survey of the actual literature is included.

Of 229 consecutive patients receiving allogeneic blood or bone marrow stem cell transplants for acute myeloid leukemia, chronic myeloid leukemia, or myelodysplastic syndrome between 1974 and 1996, 52 patients relapsed. The original tumor recurred as granulocytic sarcoma (chloroma) in three patients (1.3%). Chloroma was found in the ovary in two patients and in the central nervous system in one patient. None of these three patients had experienced > or = grade II acute or more than limited chronic graft-versus-host disease. The intervals between transplantation and recurrence with chloroma were 2, 6, and 13 years. Two patients received a second transplant, and all three died of treatment sequelae.

Chloroma or granulocytic sarcomas (GSs) are solid tumors originating from myeloid precursors. Most frequently they occur in acute myeloid leukemia (AML), myeloproliferative disorder, and myelodysplasia. It may involve any organ system, but mostly it affects the bone and soft tissue of the head and neck. Granulocytic sarcoma resulting in spinal cord compression is rare. The association between t(8;21), and GS has been reported. In spite of the fact that t(8;21) is considered to be associated with good prognosis, patients with GS and spinal cord compression had less favorable prognosis than other AML patients with t(8;21). Radiotherapy, chemotherapy, and surgical decompression are the accepted methods of therapy. However, aggressive therapy such as transplantation may be warranted early in the therapeutic strategy. Pregnancy associated with AML is rare. In our research, only one case of pregnancy with GS and AML has been previously reported. We are reporting a pregnant female diagnosed with AML/M2 with t(8;21) at the first trimester, who relapsed with GS, and cord compression at full term. She had a normal baby, and achieved second remission post-chemotherapy. Unfortunately, shortly after this she had a relapse, and died.
