One year later, while PML-RARA negative on FISH and RT-PCR, the patient presented with thrombocytopenia.     ///    FISH using dual-color translocation probes for PML (promyelocytic leukemia) and RARA (retinoic acid receptor-alpha) showed fusion signal for PML-RARA on both arms of i(17q).     ///    The patient attained complete remission (CR) with all-trans retinoic acid treatment and became PML-RARA negative.
