ABSTRACT
Acute promyelocytic leukemia (APL/AML- M3) is a distinct subtype of acute myelogenous leukemia, which is characterized by unique morphologic, cytogenetic, molecular, and clinical features. In almost all APL patients, a characteristic t(15;17)(q22;q21) is found, resulting from the fusion of the PML gene and retinoic acid receptor alpha (RAR ) gene. This chromosomal translocation in APL may present variant translocations, and may be associated with secondary chromosomal abnormalities. The most frequent accompanying karyotypic aberration is trisomy 8 in APL. We are reporting a case of a 17-year-old woman who was diagnosed with APL. Cytogenetic study revealed that 46, XX, del(5)(q23)/47, XX, del(5)(q23), +8 chromosomal abnormality but without t(15;17). However, the presence of PML/RAR chimera was found with reverse transcriptase PCR. It is well known that the association of trisomy 8 on top of t(15;17) in APL cases. However, in our review, the mosaicism of del(5)(q23) with trisomy 8 in APL might be the first case. Whether this patient will behave the typical APL cases having good prognosis or not will be interesting to see.
