Acute Myeloblastic Leukemia (M0) with an Unusual Chromosomal Abnormality: Translocation (1;14)(p13;q32)

We describe a case of acute myeloblastic leukemia, French-American-British subclassification of M0 (AML-M0), with an unusual chromosomal abnormality. The diagnosis of AML-M0 was made morphologically, cytochemically, and immunophenotypically. At the time of diagnosis, cytogenetic studies were performed, revealing a translocation involving chromosomes 1 and 14--specifically t(1;14)(p13;q32). The patient responded to high-dose ARA-C. In our survey of the literature, we were unable to find a reported case of AML-M0 with this chromosomal translocation.
