Rarely, they may exhibit either a blastoid morphology or features that are intermediate between a DLBCL and Burkitt lymphoma (the so-called intermediate\/blastoid morphology); the term high-grade B-cell lymphoma (HGBL) is used to describe the latter.

Herein, we report a rare occurrence of a double-hit lymphoma with plasmablastic features in a patient with a history of follicular lymphoma (FL) aberrantly expressing keratin in the transformed component posing a diagnostic conundrum. Immunohistochemistry and molecular work-up in conjunction with clinical history were essential in arriving at the correct diagnosis and thus illustrating a diagnostic pitfall.\n                  <\/jats:p>","DOI":"10.1177\/10668969261455058","type":"journal-article","created":{"date-parts":[[2026,6,10]],"date-time":"2026-06-10T09:07:51Z","timestamp":1781082471000},"page":"2125-2131","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["A \u201cDouble-Hit\u201d Lymphoma With Plasmablastic Features and Aberrant Keratin Expression Likely Transforming From Follicular Lymphoma"],"prefix":"10.1177","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-5548-7762","authenticated-orcid":false,"given":"Adam","family":"Lyle","sequence":"first","affiliation":[{"name":"University of Utah School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jay L.","family":"Patel","sequence":"additional","affiliation":[{"name":"University of Utah School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8674-2608","authenticated-orcid":false,"given":"Girish","family":"Venkataraman","sequence":"additional","affiliation":[{"name":"University of Chicago"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4075-4961","authenticated-orcid":false,"given":"Madhu P","family":"Menon","sequence":"additional","affiliation":[{"name":"University of Utah School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,6,10]]},"reference":[{"key":"e_1_3_2_2_2","volume-title":"Haematolymphoid tumours","author":"WHO Classification of Tumours Editorial Board","year":"2024","unstructured":"WHO Classification of Tumours Editorial Board.
