Abstract
Chronic lymphoid leukemia (CLL) is a lymphoproliferative disorder with clonal proliferation and accumulation of mature B-cells in BM, peripheral blood, and secondary lymphoid organs. Most patients show del(13q), del(11q), +12, del(17p), and del(6q) genetic abnormalities, and chromosomal translocation has been rarely reported in them. We report a 43-year-old man diagnosed with CLL with two additional marker chromosome segments of unknown origin 48, XY, +mar, +mar analyzed by G-banded karyotype analysis. Peripheral blood smear revealed markedly increased white blood cell count (WBC, 84,000/mm3) with predominance of lymphoid cells with dense chromatin. To our knowledge, this chromosomal abnormality in CLL has not been previously described, and we report it for the first time from Iran.
