A seventy-five-year-old female with general fatigue, high fever and anemia was admitted. Her chest X-ray film revealed pneumonia. She was diagnosed as RAEB-t with the normal karyotype by peripheral blood film and bone marrow aspiration; 125 micrograms/ml of G-CSF was administered s.c. daily in order to increase neutrophil count because of the prolongation of pneumonia. Her blast cells in both peripheral blood and bone marrow showed a remarkable increase by G-CSF. After the cessation of G-CSF administration, blast cells decreased rapidly, and neutrophil count in the peripheral blood increased. Her pneumonia was then cured. After 5 months of stable hematological state, 60% of her bone marrow cells became occupied by blast cells again. So 2 consecutive courses of 14 days p.o. administration of 1,200 mg MST-16/day were tried. Three months after the first MST-16 trial, her bone marrow showed complete remission (CR) which lasted about 4 months. But she died of sepsis after the first relapse. Her bone marrow in CR still revealed several features of dyspoiesis.

A 36-year-old man was diagnosed as having RAEB in 1986, and required blood transfusion regularly because of severe anemia. He received the first bone marrow transplantation following total-body irradiation and etoposide infusion in October 1987. He was found to be relapsed into RAEB on 106th day after BMT. And the second BMT was planned. According to the conditioning regimen of Tutschka, et al, we administrated busulfan and cyclophosphamide before re-transplantation. On 26th day after BMT, the WBC count exceeded 1,000/microliters and anemia was improved, while thrombocytopenia persisted until 50th day. Normal hematopoiesis in the bone marrow was confirmed on the 29th day. No severe side effect except for a little fevering and bleeding was found during the clinical course. Unfortunately he died of pneumonia following graft versus host disease on the 166th day after re-BMT. This new conditioning regimen is considered to be a choice for the high risk patients on re-transplantation.

It has been proposed that intensive chemotherapy ror RAEB is dangerous, and a small dose of ara-C therapy is recommended in many institutes for its ability to differentiate leukemic cells. Combination chemotherapy for RAEB, however, has not been completely evaluated. We introduced B-DOMP therapy, which is used in our hospital, for RAEB. B-DOMP therapy includes Behenoyl ara-C, daunomycin, oncovin, 6-MP and prednisolone, which achieved approximately 80% of complete remission of ANLL for adults. Five males and one female of RAEB, aged 40-74 (median 70), were treated by B-DOMP regimen. Two cases achieved complete remission, 2 remained in partial remission and 2 cases died within one month. In three cases, the cause of death was fungal pneumonia. It must be stressed that life-threatening pneumonia was common after chemo therapy for RAEB, and careful protection against fungal infection using laminarair flow is required.

We report a patient with refractory anemia with excess blasts who showed a lineage-unrestricted hematologic response to granulocyte colony-stimulating factor (G-CSF). After 17 months of a stable disease state, the patient developed pneumonia, progression of cytopenia, and reduced cellularity and blast mass in the bone marrow. He was given G-CSF to overcome the pneumonia. Not only the neutrophil count, but also the platelet count increased soon after initiation of the G-CSF therapy; both counts became normal on the fifth day of the G-CSF therapy. Additionally, the anemia improved gradually. The neutrophil and platelet counts were maintained in the normal range for 3 months after cessation of the G-CSF. In vitro studies showed that G-CSF alone stimulated megakaryocyte colony formation from bone marrow mononuclear cells (BMMNC), and accessory cells in the BMMNC were necessary for expression of this G-CSF-induced in vitro megakaryocytopoiesis. These results suggest that, in coordination with accessory cells, G-CSF stimulated megakaryocytopoiesis in the patient. This case provides valuable information for understanding the mechanisms of a lineage-unrestricted hematologic response to G-CSF, which is very rarely observed in MDS.

In a study of 94 patients with myelodysplastic syndrome (MDS) associated vasculitis was observed in 5, which preceded hematologic diagnosis in 4. Leukocytoclastic vasculitis was observed in 5 cases being associated to lobular panniculitis in one. Three patients had refractory anemia, one sideroblastic anemia (SA) and another refractory anemia with excess blasts (RAEB). In the latter case lymphomatoid papulosis was also observed which, to date, has not been previously described in association with MDS. Another case presented seronegative polyarthritis and renal disease coinciding with vasculitis. Polyarteritis nodosa was diagnosed in a third patient in agreement with the criteria of the American College of Rheumatology, the association of which with MDS is exceptional. In the same case medullary cytogenetic study showed 46, XY,t (12;20), an abnormally which has not been described to date in cases of MDS. All the cases were treated with glucocorticoids in addition to cyclophosphamide in the patient with polyarteritis nodosa, with an improvement in the vasculitis being observed in all the patients. Two patients died, one (SA) due to pneumonia and the other (RAEB) due to subdural hematoma following transformation to acute myeloblastic leukemia. With 5% of the MDS studied presenting vasculitis, this syndrome should be included in the differential diagnosis of vasculitis observed in patients with cytopenia.

A 78 year old female was found to have pancytopenia in February 1991. Bone marrow was normocellular with 11.7% blasts and showed dysmegakaryopoietic changes. A diagnosis of MDS (RAEB) was made and she was treated with transfusions and ubenimex. Leukemic transformation was noted in July. On Admission in October 1991, her laboratory examinations revealed the following: WBC 38,900/microliters with 93% blast, Hb 8.0 g/dl, Plt 2.1 x 10(4)/microliters, a hypercellular bone marrow with 74% blasts which were negative for myeloperoxidase (MPO) by light microscopy, but were positive by electron microscopy. Surface marker for CD13 was positive. These findings corresponded to M0 of the FAB subtype. Chromosome analysis revealed Ph1 chromosome with 46XX, t (9;22) (q34;q11) in 3 of 3 cells examined, Southern analysis showed the rearrangement of the break point cluster region (bcr). Reverse transcriptase polymerase chain reaction technique demonstrated the presence of major bcr/abl mRNA. She was treated with transfusions and methyl-prednisolone. Her blast counts declined and Ph1 chromosome was only positive in 1 of 12 metaphases examined. She died of pneumonia in December 1991. Eleven cases with MDS showing Ph1 chromosome have previously been reported. The observations indicate that Ph1 chromosome positive acute leukemias were heterogenous in nature.

The patient, a Japanese male born to a highly consanguineous family, was diagnosed as Bloom's syndrome at the age of 33 when he presented with diabetes mellitus and refractory anemia with excess blasts. Chromosome abnormalities of bone marrow cells included 5q-, -7/7q-, and unusual translocations. During the ensuing years, he developed squamous cell carcinoma of the external auditory meatus, adenocarcinoma of the colon, and squamous cell carcinoma of the tonsil. The patient died of pneumonia at the age of 38. Autopsy revealed intestinal polyposis and hemochromatosis secondary to massive blood transfusions.

An unusual case of Werner's syndrome with myelodysplastic syndrome (MDS) in a 63-year-old male is reported. He was transferred to our hospital for evaluation of pancytopenia in August 1994. He had surgery for cataracts at age 47. On admission, his weight was 39 kg and his height was 148 cm. He looked pale, had thin limbs, a bird-like face, loss of hair, a hoarse voice, and atrophic skin with ulcers. A complete blood count showed: hemoglobin 8.7 g/dl; platelet count 1.5 x 10(4)/microliters; and white blood cell count 2,900/microliters with 3% blasts. A bone marrow aspiration revealed hypercellularity with 11.8% blasts and trilineage myelodysplasia. A diagnosis of RAEB was made according to the FAB classification. Cytogenetic analysis of the bone marrow cells revealed multiple aberrations such as 44, XY, -3, -5, add (4) (q?31), add(6) (p2?), del(7) (q22), add(10) (q24), del(12) (q?), add(14) (q32), -15, -16, -17, + mar1, +mar2, +mar3. He died of pneumonia on day 11. Although approximately 700 cases (about 300 cases in Japan) of Werner's syndrome have been reported, the occurrence of hematopoietic malignancies in Werner's syndrome is rare, and the literature includes 8 cases of leukemia and 4 cases of MDS.

We report the case of a 36 year old man who was hospitalized with pneumonia and pancytopenia with refractory anemia with excess blasts confirmed by bone marrow biopsy. He was subsequently found to have advanced HIV infection. Both the HIV infection and the myelodysplastic syndrome responded to highly active anti-retroviral therapy (HAART) with sustained normalization of his hematologic abnormalities within 79 days.

A 77-year-old man was referred to our hospital because of elevated LDH and leukoblastosis in the peripheral blood in June 2002. Physical examination revealed neither hepatosplenomegaly nor superficial lymphadenopathy. A bone marrow film showed dysmegakaryocytopoiesis with many micromegakaryocytes and MPO-positive blasts appearing in 20-30% of NCC. A diagnosis of MDS (RAEB-t) was made. Blastic cells were positive for CD13, 33, 34 and HLA-DR. Karyotypic analysis at diagnosis revealed 46XY, inv(3) (q21q26), t(9;22) (q34; q11) and minor-BCR/ABL chimeric m-RNA was detected by RT-PCR. Mild chemotherapy (low dose Ara-C etc) was given but the disease progressed to the AML stage with thrombocytosis in August. In September imatinib was given because of Ph positivity, but the effect was transient. In October massive leukocytosis with myeloblastosis was uncontrollable. In December 2002 the patient died of pneumonia, after a total course of 7.5 months. This rare case with Ph chromosome and 3q21q26 syndrome showed a poor prognosis as previously reported.
