A 66-year-old man was presented with thrombocytosis in February, 1988. Laboratory examinations on admission revealed a white blood cell count of 17,700/microliters and a platelet count of 274.4 x 10(4)/microliters. Bone marrow aspirates showed an increase of megakaryocytes (1,294/microliters). There was no fibrosis or Ph1 chromosome. He was diagnosed as having essential thrombocythemia and was treated with thrombopheresis, carboquone and ranimustine (MCNU). Subsequently his platelet count was well controlled approximately for three years. He was readmitted because of pyrexia and left hypochondralgia in February 1991. Physical examination revealed hepatosplenomegaly. Peripheral blood revealed leukoerythroblastosis associated with the occurrence of tear drop cells. Bone marrow aspiration resulted in a dry tap and the biopsy specimen showed reticulin fibrosis. This is a fairly rare case of essential thrombocythemia that transformed to myelofibrosis.

A 72-year-old male had complained of right back pain and bleeding from his tongue. He was admitted to our department on May 18, 1989. Physical examination revealed hepatosplenomegaly. Peripheral blood findings were as follows: RBC was 3.80 x 10(6)/microliters. Hb 12.2 g/dl, Ht 36.5%, platelet count 735 x 10(3)/microliters, WBC 22,100/microliters, leukoerythroblastosis present. Neutrophil alkaline phosphatase score was normal. Serum vitamin B12 and plasma platelet-derived growth factor level were elevated. Skeletal X-ray revealed multiple punched-out lesions at the 8th thoracic vertebra, and 6th and 8th ribs. Serum IgG level was 3,900 mg/dl. Serum immunoelectrophoresis revealed IgG lambda-type M-protein. Because he complained of severe cervical pain, and skeletal X-ray examination revealed the fracture of 6th cervical vertebra, the operation was performed to remove the lesion. Biopsy of cervical lesion revealed plasmacytoma. M-protein was decreased and the size of the tumor was reduced after treatment with VCAP (vincristine, cyclophosphamide, adriamycin, prednisolone) regimen and interferon-alpha for multiple myeloma.

A 74-year-old man was admitted to the National Defense Medical College Hospital because of purpura on the extremities. The blood hemoglobin level was 11.5 g/dl, the white blood cell count 7. 3 x 10(9)/l with 3% blastic cells, and the platelet count 4.0 x 10(9)/l. There was leukoerythroblastosis with only mild teardrop appearance of erythrocytes. The blastic cells consisted of two types, megakaryoblast-like cells and myeloblast-like cells. There was a very mild hepatosplenomegaly, but no lymphadenopathies. The bone marrow aspirations yielded dry taps. The marrow biopsy specimen revealed myelofibrosis associated with trilineage hyperplasia, but no apparent infiltration of leukemic cells. Platelet-associated IgG (PAIgG) had a high titer and the response to platelet transfusions was poor. On prednisolone and colchicine, the blastic cells in the peripheral blood disappeared and the platelet count increased. He died of pneumonia. The autopsy showed myelofibrosis with hyperplasia of myeloid and erythroid lineage in the bone marrow. Megakaryocytes were relatively few and there was no infiltration of leukemic cells.

A 70-year-old man, who had been diagnosed as primary myelofibrosis in 1987 at Tokyo Women's Medical School, was admitted to our hospital because of left hip-joint pain in May 1988. Physical examinations revealed marked hepatosplenomegaly and multiple reddish papules on the skin. The peripheral blood showed marked leukoerythroblastosis and severe anemia with poikilocytosis. Bone marrow aspirations were dry tap. Needle biopsy of iliac crest showed a diffuse fibrosis. Biopsy of the papules showed an extramedullary haematopoiesis. He was treated with low dose Ara-C for seven days. Although hepatosplenomegaly and skin papules were reduced, he died of pneumonia a month later. At autopsy, leukemic cells massively infiltrated into the multiple organs, including bone marrow. The cells were identified with megakaryoblast, as those were positive for factor VIII related antigen. As far as we know, this is the third case of primary myelofibrosis transformed into acute megakaryoblastic leukemia.

A patient with chronic myeloproliferative disorder (CMPD) developed Sweet's syndrome during granulocyte colony-stimulating factor (G-CSF) therapy. A 61-year-old man with essential thrombocythemia was treated with busulfan intermittently since April, 1991. In February, 1993, hepatosplenomegaly with leukoerythroblastosis arose and a diagnosis of myelofibrosis with extramedullary hematopoiesis in the spleen was established. For alleviation of left hypochondralgia due to splenomegaly, he received splenic irradiation in September, 1993. Soon after the irradiation, his peripheral blood revealed pancytopenia and then administration of rhG-CSF was begun on the 9th of October, 1993. One week after G-CSF therapy, he became feverish and painful eruptions on the face and the upper extremities appeared and enlarged. Skin biopsy resulted in a diagnosis of Sweet's syndrome. Treatment with oral prednisone, 30 mg daily, was begun, and rapid and significant improvement of the skin lesions was obtained. The pathogenesis of Sweet's syndrome remains obscure, but careful follow up is necessary for patients during G-CSF therapy with respect to development of Sweet's syndrome.

Myelofibrosis with myeloid metaplasia, or agnogenic myeloid metaplasia (AMM) is a chronic myeloproliferative disorder characterized by fibrosis of the bone marrow accompanied by aniso- and poikilocytosis, leukoerythroblastosis and hepatosplenomegaly with extramedullary hematopoiesis. Agnogenic myeloid metaplasia is very rare in children. In this report, two cases of AMM in whom the onset of the illness were at 3 and 12 months of age, are presented. Both had severe anemia, hepatosplenomegaly and bone marrow fibrosis. Lymph node biopsy of the first patient and liver biopsy of the second revealed extramedullary hematopoiesis. They were treated with an intravenous high dose of methylprednisolone (daily 30 mg/kg for 3 days, 20 mg/kg for 4 days, 10 mg/kg for 1 week, 5 mg/kg for 1 week). A complete improvement of hematological and clinical findings was observed.

A 60-year-old Japanese woman was admitted to our hospital because of fatigue, weight loss and abdominal distension. Myelofibrosis was diagnosed, based on anemia, huge hepatosplenomegaly, leukoerythroblastosis and bone marrow fibrosis. Following treatment with ranimustine, anemia and splenomegaly improved. Seven months after initial therapy of ranimustine, however, polycythemia (RBC 7.39 x 10(6)/microliter; Hb 19.1 g/dl, Ht 65.9%) developed gradually, then RBC decreased to normal level following venesection (total 1,200 ml). After 32 months, blastic transformation occurred. The blasts were negative for myeloperoxidase. By flow cytometric analysis, the cells were positive for CD2, CD13, CD33 and HLA DR. Thus, AML (M0) was diagnosed. Despite of treatment with multicytotoxic agents, she died of DIC 36 months after the initial diagnosis of myelofibrosis. The progression from myelofibrosis to polycythemia is rare and only 15 cases have been reported so far. In addition, although a chromosomal abnormality, 46, XX, t(3; 12) (q25; p11), was present at the time of first diagnosis of myelofibrosis, the development of an additional abnormality, del(11) (q-), might be related to the transformation to AML.

A 60-year-old woman was admitted in August 1995 complaining of abdominal pain. A diagnosis of essential thrombocythemia had been made in 1987, and myelofibrosis developed in the patient thereafter. Physical examination revealed massive hepatosplenomegaly, and the peripheral blood showed leukoerythroblastosis with chromosomal abnormalities in peripheral blood cells. In May, 1996, blastic transformation occurred. Based on the findings of surface marker analysis, the blasts met the diagnostic criteria for acete myelogenous leukemia because they were negative for peroxidase and positive for CD13. In June, the patient died of multiple organ failure. Postmortem examination revealed multiple tumor emboli.

We described the successful allogeneic matched sibling bone marrow transplantation (BMT) in a 5-year-old Thai boy in whom osteopetrosis was diagnosed on the basis of anemia, thrombocytopenia, leukoerythroblastosis, sclerotic bone, hepatosplenomegaly, and visual deficit from an encroachment of cranial nerve foramina. The preparative regimen included 4 days of busulfan 4 mg/kg/day, and 4 days of cyclophosphamide 50 mg/kg/day. Complete hematopoietic engraftment and no evidence of graft versus host disease were shown after BMT. Complete hematologic findings were corrected. His hematopoietic chimerism was changed to that of his donor. Post BMT, he has no hepatosplenomegaly. His bone radiographic findings revealed normal after BMT. Bone marrow biopsy showed normalized bone and bone marrow matrix. However, his vision remained impaired. We believe that this is the first case of successful bone marrow transplantation in an osteopetrosis patient in Thailand.

A 60-year-old woman was admitted to our hospital in February 1993 due to dizziness, dyspnea, abdominal pain, and high susceptibility to bleeding. Physical examination revealed livedo reticularis of the foot, but did not detect hepatosplenomegaly. Examination of the peripheral blood detected pancytopenia, leukoerythroblastosis, and tear-drop erythrocytes. Primary myelofibrosis (PMF) was diagnosed on the basis of bone marrow biopsy findings. Antiphospholipid syndrome (APS) was confirmed by positive response to anti-cardiolipin antibody and recurrent splenic infarction. Because of factor XIII deficiency, the patient experienced severe gingival bleeding after tooth extraction. Her condition was complicated by mesenteric arterial thromboembolism and she died of sepsis 5 years after onset. Although the incidence of immunopathy in PMF patients is high, few studies to date have focused on APS patients presenting with a variety of severe embolic symptoms. Our patient required careful monitoring due to bleeding tendency and thromboemboli.
