Here, we retrospectively collected 310 canine lymphomas with an aberrant phenotype detected via flow cytometry and describe their clinical and clinical pathological features at diagnosis. There were 152 T-cell lymphomas not otherwise specified (T-NOS), 101 T-zone lymphomas (TZL), 54 B-cell lymphomas, and 3 cases with two suspected concurrent neoplastic populations. The most represented aberrancies were: CD5-, CD4-CD8-, and CD3- in T-NOS lymphomas, CD21+, CD4-CD8-, and CD3- in TZLs, and CD34+, CD44-, and CD5+ in B-cell lymphomas. Among T-cell lymphomas, the aberrant expression of CD21 was significantly more frequent in TZL and the loss of CD5 and CD44 in T-NOS. More than 75% of dogs were purebred; males outnumbered females; the mean age at diagnosis was 8\u201310 years, depending on lymphoma subtype. A few dogs were symptomatic at the time of diagnosis, and 30% had peripheral blood abnormalities, in line with what is already reported for the general population of dogs with lymphoma. Further studies are needed to assess the pathogenetic mechanisms underlying each specific antigen aberrancy, as well as the diagnostic and prognostic role.<\/jats:p>","DOI":"10.3390\/vetsci9040184","type":"journal-article","created":{"date-parts":[[2022,4,13]],"date-time":"2022-04-13T23:07:16Z","timestamp":1649891236000},"page":"184","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Clinical and Clinical Pathological Presentation of 310 Dogs Affected by Lymphoma with Aberrant Antigen Expression Identified via Flow Cytometry"],"prefix":"10.3390","volume":"9","author":[{"given":"Elena","family":"Celant","sequence":"first","affiliation":[{"name":"Department of Veterinary Medicine and Animal Sciences, University of Milan, Via dell\u2019Universit\u00e0 6, 26900 Lodi, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7843-615X","authenticated-orcid":false,"given":"Laura","family":"Marconato","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Sciences, University of Bologna, Via Tolara di Sopra 50, Ozzano dell\u2019Emilia, 40064 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2726-0366","authenticated-orcid":false,"given":"Damiano","family":"Stefanello","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine and Animal Sciences, University of Milan, Via dell\u2019Universit\u00e0 6, 26900 Lodi, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9708-5148","authenticated-orcid":false,"given":"Pierangelo","family":"Moretti","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine and Animal Sciences, University of Milan, Via dell\u2019Universit\u00e0 6, 26900 Lodi, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7893-1740","authenticated-orcid":false,"given":"Luca","family":"Aresu","sequence":"additional","affiliation":[{"name":"Department of Veterinary Sciences, University of Turin, Largo Braccini 2, Grugliasco, 10095 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1567-8055","authenticated-orcid":false,"given":"Stefano","family":"Comazzi","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine and Animal Sciences, University of Milan, Via dell\u2019Universit\u00e0 6, 26900 Lodi, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9882-2867","authenticated-orcid":false,"given":"Valeria","family":"Martini","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine and Animal Sciences, University of Milan, Via dell\u2019Universit\u00e0 6, 26900 Lodi, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"421","DOI":"10.1111\/j.1365-2141.2011.08595.x","article-title":"Review of the relevance of aberrant antigen expression by flow cytometry in myeloid neoplasms","volume":"153","author":"Ossenkoppele","year":"2011","journal-title":"Br.
