ABSTRACT
We report one case of pediatric acute myeloid leukemia type 2 (AML-M2) who presented with karyotypic aberration of trisomy 21 with the t(5;ll) chromosomal translocation.The patient achieved complete remission after two cycles of chemotherapy of daunorubicin,cytarabine and etoposide.Then,follow-up cytogenetic analysis from bone marrow cell cultures demonstrated a normal karyotype of 46,XY.After 9 years,the patient relapsed and the karyotypic abnormalities of trisomy 21 with t(5;ll) reappeared.It was concluded that trisomy 21 with t(5;11) is a new unfavorable cytogenetic aberration in AML-M2.
