title: Acute promyelocytic leukemia with del(6)(p23).
abstract: We report a unique case of de novo acute promyelocytic leukemia (APL) with cryptic 15;17 rearrangements. Cytogenetically, structural rearrangements of the 6p23 region has been reported mainly in secondary leukemia. This patient had a karyotype of 46, XY, del(6)(p23) and no additional chromosomal abnormalities. Molecular analyses revealed the presence of PML-RAR alpha fusion genes. Deletion of the 6p23 region is extremely rare in APL.
