Abstract

Congenital, or perinatal, leukemias are rarely observed, but retrospective molecular studies seem to suggest a more frequent onset in prenatal life. Myelocytic types are common, and chromosome band 11q23 rearrangements at the MLL locus are characteristic genetic markers. The fusion of the MLL gene with one of its partners, ABI-1, has recently been described in two infant leukemia patients with monocytic involvement and good clinical outcome. We report a case of congenital monocytic leukemia with the same gene involvement and good response to chemotherapy. The blast metaphases were probed by fluorescence in situ hybridization, and t(10;11)(p11.2;q23) involving MLL and ABI-1 genes was demonstrated with the same breakpoint in ABI-1. The congenital presentation of this case suggests a possible relationship of this genetic event with in utero leukemogenesis.
