In this study, by using polymerase chain reaction and fluorescence in situ hybridization techniques, we have showed that there is neither t(14;18)/IGH-BCL2 nor IGH gene rearrangement in 4 de novo IDCS without a concurrent or known history of a B-cell lymphoma, including follicular lymphoma, indicating that BCL2 chromosomal translocation is not a general feature of de novo IDCS.
