A case of AML presented with basophilia in peripheral blood and Ph1 chromosome in karyotype analysis is reported. After one year of treatment with intensive chemotherapy and clinical and hematological remission, molecular analysis (RT-PCR) detected minimal residual disease (b2-a2 rearrangement). Thus, the patient relapsed as AML and, after second remission, he developed a hematological picture of chronic CML. Ten months later, he relapsed again as AML. The difficulties of diagnosis between AML Ph1-positive de novo and myeloid blast crisis of CML, as the first manifestation of disease, based on clinical and molecular aspects are discussed.

D015464	Leukemia, Myelogenous, Chronic, BCR-ABL Positive	Clonal hematopoetic disorder caused by an acquired genetic defect in PLURIPOTENT STEM CELLS. It starts in MYELOID CELLS of the bone marrow, invades the blood and then other organs. The condition progresses from a stable, more indolent, chronic phase (LEUKEMIA, MYELOID, CHRONIC PHASE) lasting up to 7 years, to an advanced phase composed of an accelerated phase (LEUKEMIA, MYELOID, ACCELERATED PHASE) and BLAST CRISIS.

D016133	Polymerase Chain Reaction	In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.

This should be differentiated from DEATH, the physiological cessation of life and from MORTALITY, an epidemiological or statistical concept.	Fatal Outcomes,Outcome, Fatal,Outcomes, Fatal
