    Abstract:
    The t(11;14)(q13;q32) is a hallmark of mantle cell lymphoma. It has been found less frequently in other lymphoproliferative disorders, such as B-prolymphocytic leukemia, plasma cell leukemia, chronic lymphocytic leukemia, and multiple myeloma. Here, we describe a patient with acute myeloid leukemia (AML), categorized as M5b according to French-American-British classification, in which conventional cytogenetic analysis revealed a karyotype with t(11;14)(q13;q32). Fluorescence in situ hybridization analyses demonstrated no rearrangement of the immunoglobulin heavy-chain (IGH) (14q32) locus as well as of the cyclin D1 (CCND1) gene, suggesting that this is not the typical t(11;14) resulting from the CCND1/IGH fusion. The changes in the 11q13 region have been described in both myeloid and lymphoid neoplasm with different chromosomes serving as donors in translocation, but to the best of our knowledge, never with the chromosome 14.
