Abstract
IGH::CCND1 translocation has been implicated as a preliminary finding in mantle cell lymphoma (MCL) and plasma cell myeloma, with cyclin D1 over-expression by immunohistochemistry stain, without gene rearrangement, reported in other hematologic neoplasms. CCND1 rearrangement has been reported infrequently as a secondary event in high-grade B-cell lymphomas. We present the case of an elderly man who was found to have a splenic marginal zone lymphoma with a heterozygous TP53 deletion. Years later at the time of relapse, the patient acquired a CCND1 rearrangement, in addition to a persistent TP53 deletion. Sequencing of the two lymphomas demonstrated clonal relatedness of the two processes. To our knowledge, this is the first report of a splenic marginal zone lymphoma with a TP53 deletion at diagnosis, evolving into a large B-cell lymphoma with a CCND1 rearrangement.
期刊介绍:
Manuscripts of original studies reinforcing the evidence base of modern diagnostic pathology, using immunocytochemical, molecular and ultrastructural techniques, will be welcomed. In addition, papers on critical evaluation of diagnostic criteria but also broadsheets and guidelines with a solid evidence base will be considered. Consideration will also be given to reports of work in other fields relevant to the understanding of human pathology as well as manuscripts on the application of new methods and techniques in pathology. Submission of purely experimental articles is discouraged but manuscripts on experimental work applicable to diagnostic pathology are welcomed. Biomarker studies are welcomed but need to abide by strict rules (e.g. REMARK) of adequate sample size and relevant marker choice. Single marker studies on limited patient series without validated application will as a rule not be considered. Case reports will only be considered when they provide substantial new information with an impact on understanding disease or diagnostic practice.
