Here, we report an IVLBCL in a 47-year-old Asian man. Morphologically, the atypical lymphoid infiltrate was entirely confined in the lumina of capillaries, small vessels, and sinusoidal space. Within the kidney, the neoplastic lymphoid cells exhibited both the glomerular and peritubular capillary distribution pattern. Conventional cytogenetic analysis from the bone marrow aspirates displayed a complex karyotype, with a notable triple tandem repeat at band segment q22\u2013q25 of chromosome 11. Fluorescence in situ hybridization with an MLL probe set, performed on both interphase cells and metaphase spreads, confirmed the presence of 3 copies of the MLL gene on the derivative chromosome 11. From this finding and 3 other IVLBCL cases reported in the literature, we conclude that MLL may play an important role in the lymphomagenesis of IVLBCL at least in a subset of cases.<\/jats:p>","DOI":"10.5858\/133.9.1477","type":"journal-article","created":{"date-parts":[[2021,2,12]],"date-time":"2021-02-12T11:02:37Z","timestamp":1613127757000},"page":"1477-1482","source":"Crossref","is-referenced-by-count":17,"title":["Segmental Tandem Triplication of the\n                    <i>MLL<\/i>\n                    Gene in an Intravascular Large B-Cell Lymphoma With Multisystem Involvement: A Comprehensive Morphologic, Immunophenotypic, Cytogenetic, and Molecular Cytogenetic Antemortem Study"],"prefix":"10.5858","volume":"133","author":[{"given":"Jeremy","family":"Deisch","sequence":"first","affiliation":[{"name":"From the Department of Pathology, the University of Texas Southwestern Medical Center at Dallas, Dallas, Texas."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Franklin\u201cBuddy\u201d","family":"Fuda","sequence":"additional","affiliation":[{"name":"From the Department of Pathology, the University of Texas Southwestern Medical Center at Dallas, Dallas, Texas."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weina","family":"Chen","sequence":"additional","affiliation":[{"name":"From the Department of Pathology, the University of Texas Southwestern Medical Center at Dallas, Dallas, Texas."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nitin","family":"Karandikar","sequence":"additional","affiliation":[{"name":"From the Department of Pathology, the University of Texas Southwestern Medical Center at Dallas, Dallas, Texas."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arnaldo A.","family":"Arbini","sequence":"additional","affiliation":[{"name":"From the Department of Pathology, the University of Texas Southwestern Medical Center at Dallas, Dallas, Texas."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin J.","family":"Zhou","sequence":"additional","affiliation":[{"name":"From the Department of Pathology, the University of Texas Southwestern Medical Center at Dallas, Dallas, Texas."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huan-You","family":"Wang","sequence":"additional","affiliation":[{"name":"Reprints: Huan-You Wang, MD, PhD, Department of Pathology, University of Texas Southwestern Medical Center at Dallas, 5323 Harry Hines Blvd, Dallas, TX 75390 (huan-you.wang@utsouthwestern.edu)."},{"name":"From the Department of Pathology, the University of Texas Southwestern Medical Center at Dallas, Dallas, Texas."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3906","reference":[{"key":"2021021103010753000_i1543-2165-133-9-1477-b1","doi-asserted-by":"crossref","first-page":"3168","DOI":"10.1200\/JCO.2006.08.2313","article-title":"Definition, diagnosis, and management of intravascular large B-cell lymphoma: proposals and perspectives from an International Consensus Meeting.","volume":"25","author":"Ponzoni","year":"2007","journal-title":"J Clin Oncol"},{"key":"2021021103010753000_i1543-2165-133-9-1477-b2","doi-asserted-by":"crossref","first-page":"486","DOI":"10.3324\/haematol.10829","article-title":"Variations in clinical presentation, frequency of hemophagocytosis and clinical behavior of intravascular lymphoma diagnosed in different geographical regions.","volume":"92","author":"Ferreri","year":"2007","journal-title":"Haematologica"},{"key":"2021021103010753000_i1543-2165-133-9-1477-b3","doi-asserted-by":"crossref","first-page":"478","DOI":"10.1182\/blood-2006-01-021253","article-title":"Intravascular large B-cell lymphoma (IVLBCL): a clinicopathologic study of 96 cases with specific reference to the immunophenotypic heterogeneity of CD5.","volume":"109","author":"Murase","year":"2007","journal-title":"Blood"},{"key":"2021021103010753000_i1543-2165-133-9-1477-b4","doi-asserted-by":"crossref","first-page":"105","DOI":"10.1002\/hon.776","article-title":"Intravascular lymphoma;
