Abstract
Translocations involving immunoglobin (IG) are common in B-cell neoplasms. These IG translocations lead to the disposition of the enhancer or promoter of an IG locus, typically IGH, to a proto-oncogene, resulting in the elevated expression of the cancer gene. IG fusions play an important role in the diagnosis, prognostication, and therapy selection of B-cell lymphomas. A t(14;22)(q32;q11) translocation involving IGH and IGL is rare in lymphomas. We report herein clinicopathological characteristics, response to treatment, and outcomes of a first splenic marginal zone lymphoma case with a t(14;22)(q32;q11) translocation involving IGH and IGL treated with rituximab, ibrutinib, and obinutuzumab. Studies of additional cases are needed to elucidate the potential role of the t(14;22) translocation in lymphomagenesis and prognostication.
期刊介绍：
Annals of Hematology covers the whole spectrum of clinical and experimental hematology, hemostaseology, blood transfusion, and related aspects of medical oncology, including diagnosis and treatment of leukemias, lymphatic neoplasias and solid tumors, and transplantation of hematopoietic stem cells. Coverage includes general aspects of oncology, molecular biology and immunology as pertinent to problems of human blood disease. The journal is associated with the German Society for Hematology and Medical Oncology, and the Austrian Society for Hematology and Oncology.
