Aml1/ETO and Pml/RARA rearrangements in a case of AML-M2 acute myeloblastic leukemia with t(15;17)

Leuk Lymphoma. 1999 Apr;33(3-4):403-6. doi: 10.3109/10428199909058444.

Abstract

We report a case of acute myeloid leukemia FAB-type 2 with a translocation t(15;17)(q22;q12) On the basis of the cytological findings, a translocation t(8;21)(q22;q22) was suspected. FISH analyses using specific probes for t(15;17) and t(8;21) detected both PML/RARalpha and AML1/ETO rearrangements in a few percentage of cells. This case demonstrates the complexities that may occur between cytology and cytogenetic findings and the usefulness of FISH methods to detect an AML1/ETO rearrangement only suspected by cytological examination of bone marrow smears.
