In this case report and literature review, we highlight this unfortunate triad of poor prognostic features associated with an aggressive and fatal clinical course in a 53-year-old man with recrudescent DLBCL. A leukemic presentation of de novo or relapsed DLBCL is rare and may be related to differential expressions of adhesion molecules on cell surfaces. In addition, TP53 gene mutations are present in approximately 20% to 25% of DLBCL cases and foreshadow worse clinical outcomes. Finally, an elevated serum lactic acid level in DLBCL that is not clearly associated with sepsis syndrome is a poor prognostic factor for survival and manifests as type B lactic acidosis through the Warburg effect.<\/jats:p>","DOI":"10.1177\/2634853521994094","type":"journal-article","created":{"date-parts":[[2021,2,19]],"date-time":"2021-02-19T20:07:40Z","timestamp":1613765260000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["A Clinical Triad with Fatal Implications: Recrudescent Diffuse Large B-cell Non-Hodgkin Lymphoma Presenting in the Leukemic Phase with an Elevated Serum Lactic Acid Level and Dysregulation of the TP53 Tumor Suppressor Gene \u2013 A Case Report and Literature Review"],"prefix":"10.1177","volume":"14","author":[{"given":"Catherine S","family":"Hwang","sequence":"first","affiliation":[{"name":"Department of Medicine, Virginia Mason Medical Center, Seattle, WA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dick G","family":"Hwang","sequence":"additional","affiliation":[{"name":"Department of Pathology, Virginia Mason Medical Center, Seattle, WA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6752-3530","authenticated-orcid":false,"given":"David M","family":"Aboulafia","sequence":"additional","affiliation":[{"name":"Floyd and Delores Jones Cancer Institute, Virginia Mason Medical Center, Seattle, WA, USA"},{"name":"Division of Hematology, University of Washington School of Medicine, Seattle, WA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,2,19]]},"reference":[{"key":"bibr1-2634853521994094","unstructured":"World Health Organization.
