Acute promyelocytic leukemia (APL) is a distinct subtype of acute myeloid leukemia (AML) characterized by PML-RARA fusion and specific morphology. The BCR-ABL1 rearrangement is mainly observed in patients with chronic myeloid leukiemia (CML). However, it is also found in patients with acute lymphoblastic leukemia (ALL) and in a few patients with AML. However, it is very rarely observed in patients with APL. Here, we report a case of APL with t(15;17) and co-existence of PML-RARA and BCR-ABL1. Further study with more cases is warranted to find the right treatment and prognostic significance.
