We report a case of de novo diffuse large B-cell lymphoma (DLBCL) in leukemic phase, positive for both CD5 and CD13. Morphologic evaluation, flow cytometric immunophenotyping, karyotyping and polymerase chain reaction studies were performed. Neoplastic lymphocytes appeared as blast-like cells, positive for CD19, CD20, CD5, CD13, CD79a, HLADR, and with restriction for surface immunoglobulin K light chains. Rearrangement of IgH gene, BCL2/IgH translocation and complex karyotype were found. The patient was treated with RCOMP regimen and achieved complete remission. However, only one month after the first restaging of disease, the patient presented with symptoms attributable to central nervous system involvement and her clinical conditions worsened rapidly. While both CD5 expression and leukemic presentation are uncommon findings in DLBCL, positivity for CD13 is very rare. The outcome of our patient shows the poor prognosis of CD5+ DLBCL with leukemic presentation. The possible role of CD13 coexpression is discussed.

Abstract The 2016 revision of the World Health Organization (WHO) classification for lymphoma has included a new category of lymphoma, separate from diffuse large B-cell lymphoma, termed high-grade B-cell lymphoma with translocations involving myc and bcl-2 or bcl-6. These lymphomas, which occur in <10% of cases of diffuse large B-cell lymphoma, have been referred to as double-hit lymphomas (or triple-hit lymphomas if all 3 rearrangements are present). It is important to differentiate these lymphomas from the larger group of double-expressor lymphomas, which have increased expression of MYC and BCL-2 and/or BCL-6 by immunohistochemistry, by using variable cutoff percentages to define positivity. Patients with double-hit lymphomas have a poor prognosis when treated with standard chemoimmunotherapy and have increased risk of central nervous system involvement and progression. Double-hit lymphomas may arise as a consequence of the transformation of the underlying indolent lymphoma. There are no published prospective trials in double-hit lymphoma, however retrospective studies strongly suggest that aggressive induction regimens may confer a superior outcome. In this article, I review my approach to the evaluation and treatment of double-hit lymphoma, with an eye toward future clinical trials incorporating rational targeted agents into the therapeutic armamentarium.

Background: The aim of this study was to investigate the prognostic role of mammalian target of Rapamycin (mTOR) and C-X-C chemokine receptor type 4 (CXCR4) in diffuse large-B-cell lymphoma (DLBCL) patients.Patients and methods: This retrospective study was collected data from 64 de novo DLBCL patients, who received standardized R-CHOP therapy at two oncology centers. CXCR4 and mTOR expressions were assessed by immunohistochemistry.Results: Out of the 64 DLBCL patients, 40 patients were positive for CXCR4 (62.5%) and 35 patients for mTOR (54.7%) expressions. CXCR4 expression was positively correlated with mTOR expression (r = 0.7; p < .001). While mTOR expression was significantly associated with high lactate dehydrogenase level (p = .03) and number of extranodal sites one or more (p =.02), CXCR4 expression was significantly associated with high IPI score (p < .001) and ECOG PS (p = .005). Furthermore, theexpression levels of mTOR and CXCR4 were significantly associated with older ages and poor response to treatment (p = .04, <.001 and .04, .03, respectively). After a median Follow up of 22 months, mean ± SD overall survival (OS) was 65.391 ± 4.705. Kaplan–Meier analysis showed that patients positive for mTOR and CXCR4 expression had shorter DFS (p = .01 & .02) and OS (p = .02 & .04). Multivariate analysis showed that CXCR4 and mTOR positivity is an independent prognostic factor for significantly poorer DFS (p = .03, and .02 respectively) but not for OS (p = .09 and .08 respectively) in the DLBCL pateints.Conclusion: Our results indicate that the expression of CXCR4 and mTOR may be poor prognostic biomarkers in DLBCL.

The gastrointestinal tract is a common extranodal site for lymphomas. However, primary gastrointestinal lymphomas are rare. Diffuse large B-cell lymphomas (DLBCL) are the most commonly encountered type in the gastrointestinal tract. Most of the DLBCL are CD5 negative. CD5+ DLBCL is very rare and a poor prognostic subtype of lymphoma. We report a rare case of primary small bowel CD5+ DLBCL that evolved from being a localized low International Prognostic Index–scored disease into an advanced and aggressive disease primarily dictated by the presence of CD5 antigen positivity.
