Abstract

Translocation of the BCL6 gene is one of the most common chromosomal changes seen in diffuse large B-cell lymphoma, primarily affecting the 5' regulatory region which is usually replaced with the sequences of the translocation partner. This translocation involves both immunoglobulin and nonimmunoglobulin gene partners, the former being the more common. Here we report a case of diffuse large B-cell lymphoma with immunophenotypic features of a germinal center type, involving translocation of BCL6 to chromosome 11 and partnering with one or more nonimmunoglobulin genes. To our knowledge this novel translocation in the context of an activated B-cell type diffuse large B-cell lymphoma has not been previously described in the literature. We speculate about the putative partner gene involved in the translocation and the pathophysiological significance of the translocation.
