Acute myelofibrosis is a rare but distinct accelerated variant of agnogenic myeloid metaplasia that is characterized by marked anemia, peripheral blood myeloblastosis and normoblastosis, a lack of teardrop poikilocytosis, and prominent myelofibrosis. There is usually no palpable hepatosplenomegaly or lymph node enlargement. The clinical course is remarkable short. We describe a 63-year-old man who presented with idiopathic acquired sideroblastic anemia and subsequently developed acute myelofibrosis. Intensive polychemotherapy with vincristine, cytosine arabinoside, and prednisone and a later trial of oxymetholone therapy were ineffective. He died 134 days after the diagnosis of acute myelofibrosis was established. The 11 previously reported cases of acute myelofibrosis are reviewed, and the relationships of acute myelofibrosis to other myeloproliferative disorders and to idiopathic acquired sideroblastic anemia are discussed.

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.
