Immunophenotype analysis showed TdT expression with positivity of CD3 and CD7 among other T\u2010lineage markers. Other non\u2010T markers such as CD79a or myeloid\u2010associated antigens were negative. Molecular studies were performed evidencing clonal rearrangements for gamma and beta chain T cell receptor were clonal in the lymph node biopsy. Cytogenetic analysis showed deletions in CDKN2A and NOTCH2 genes. CD20 when present in T\u2010LBL can lead to a false diagnosis of B\u2010LBL. In this scenario, analysis of rearrangements of both immunoglobulin heavy chain B cell receptor and rearrangement of the T cell receptor can be very helpful.<\/jats:p>","DOI":"10.1111\/ijlh.13769","type":"journal-article","created":{"date-parts":[[2021,11,25]],"date-time":"2021-11-25T11:42:30Z","timestamp":1637840550000},"page":"234-235","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["T cell lymphoblastic lymphoma with uncommon CD20 expression"],"prefix":"10.1111","volume":"44","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3137-3443","authenticated-orcid":false,"given":"Ram\u00f3n","family":"Diez\u2010Feij\u00f3o","sequence":"first","affiliation":[{"name":"Department of Hematology Hospital del Mar Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4741-7925","authenticated-orcid":false,"given":"Juan Jos\u00e9","family":"Rodr\u00edguez\u2010Sevilla","sequence":"additional","affiliation":[{"name":"Department of Hematology Hospital del Mar Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9988-5977","authenticated-orcid":false,"given":"Marta","family":"Salido","sequence":"additional","affiliation":[{"name":"Department of Hematology Hospital del Mar Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5236-5085","authenticated-orcid":false,"given":"Luis","family":"Colomo","sequence":"additional","affiliation":[{"name":"Department of Hematology Hospital del Mar Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4652-4825","authenticated-orcid":false,"given":"Antonio","family":"Salar","sequence":"additional","affiliation":[{"name":"Department of Hematology Hospital del Mar Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,11,24]]},"reference":[{"key":"e_1_2_4_2_1","doi-asserted-by":"publisher","DOI":"10.18632\/oncotarget.2218"},{"key":"e_1_2_4_3_1","volume-title":"WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues","author":"Swerdlow SH","year":"2017"},{"issue":"10","key":"e_1_2_4_4_1","first-page":"1021","article-title":"[CD20\u2010positive T cell lymphoma: clinicopathological features of five cases]","volume":"49","author":"Shao SH","year":"2020","journal-title":"Zhonghua Bing Li Xue Za Zhi"}],"container-title":["International Journal of Laboratory Hematology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/ijlh.13769","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/ijlh.13769","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/ijlh.13769","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,25]],"date-time":"2023-08-25T22:53:20Z","timestamp":1693004000000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/ijlh.13769"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,11,24]]},"references-count":3,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2022,4]]}},"alternative-id":["10.1111\/ijlh.13769"],"URL":"https:\/\/doi.org\/10.1111\/ijlh.13769","archive":["Portico"],"relation":{},"ISSN":["1751-5521","1751-553X"],"issn-type":[{"value":"1751-5521","type":"print"},{"value":"1751-553X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,11,24]]},"assertion":[{"value":"2021-06-02","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2021-11-10","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2021-11-24","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
