Rather unexpectedly, the patient did not respond to all-trans retinoic acid administration; he attained complete remission with conventional chemotherapy and became PML/RAR alpha negative. Two years later while PML/RAR alpha negative nn RT-PCR he presented with thrombocytopenia. Bone marrow examination was compatible with myelodysplasia of the RAEB type; the karyotype was normal. Then, after 10 months, he developed overt acute myeloid leukemia with PML/RAR alpha negative, French-American-British MZ blasts; karyotypic analysis revealed mosaicism for trisomy 8.
