Radiography of the thoracic cavity revealed a severe radiopaque region in the caudal lobe of the right lung. At 108 days after the initial visit, CT showed a mass of 27\u2009\u00d7\u200923\u2009\u00d7\u200918 mm in the caudal lobe of the right lung. At that time, no abnormalities in other organs except for the lung were detected on CT and peripheral blood and blood biochemistry tests. The mass in the caudal lobe of the right lung was resected by lobectomy; it had a white surface and was firm. Histopathologically, the mass was non-encapsulated, showing an unclear boundary with surrounding tissues. The mass comprised large, round or polygonal neoplastic cells arranged in a diffuse pattern. Immunohistochemically, neoplastic cells were diffusely positive for CD20, feline leukaemia virus (FeLV) p27 and FeLV glycoprotein 70 but negative for CD3, CD204 and E-cadherin. Based on these findings, diffuse large B-cell lymphoma associated with FeLV infection was diagnosed. Although the cat showed no clinical signs of gastrointestinal or respiratory injury, a routine ultrasonography revealed thickening in the jejunum wall 196 days after lobectomy, and subsequent fine-needle aspiration examination confirmed high-grade lymphoma.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Relevance and novel information<\/jats:title>\n                    <jats:p>This is the first report of primary pulmonary diffuse large B-cell lymphoma associated with FeLV infection in a young cat.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/20551169221074240","type":"journal-article","created":{"date-parts":[[2022,2,11]],"date-time":"2022-02-11T05:22:47Z","timestamp":1644556967000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Primary pulmonary diffuse large B-cell lymphoma associated with feline leukaemia virus infection in a young cat"],"prefix":"10.1177","volume":"8","author":[{"given":"Kento","family":"Ishikawa","sequence":"first","affiliation":[{"name":"Department of Veterinary Pathology, Nippon Veterinary and Life Science University, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomokazu","family":"Nagashima","sequence":"additional","affiliation":[{"name":"Department of Veterinary Pathology, Nippon Veterinary and Life Science University, Tokyo, Japan"},{"name":"Veterinary Medical Center, Nippon Veterinary and Life Science University, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yukino","family":"Machida","sequence":"additional","affiliation":[{"name":"Department of Veterinary Pathology, Nippon Veterinary and Life Science University, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akiko","family":"Yasuda","sequence":"additional","affiliation":[{"name":"Veterinary Medical Center, Nippon Veterinary and Life Science University, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karin","family":"Yoshida","sequence":"additional","affiliation":[{"name":"Veterinary Medical Center, Nippon Veterinary and Life Science University, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michio","family":"Fujita","sequence":"additional","affiliation":[{"name":"Division of Veterinary Radiology, Nippon Veterinary and Life Science University, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuhiko","family":"Ochiai","sequence":"additional","affiliation":[{"name":"Department of Veterinary Hygiene, Nippon Veterinary and Life Science University, Tokyo, Japan"},{"name":"Research Center for Animal Life Science, Nippon Veterinary and Life Science University, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daigo","family":"Azakami","sequence":"additional","affiliation":[{"name":"Laboratory of Veterinary Clinical Oncology, Tokyo University of Agriculture and Technology, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masaki","family":"Michishita","sequence":"additional","affiliation":[{"name":"Department of Veterinary Pathology, Nippon Veterinary and Life Science University, Tokyo, Japan"},{"name":"Research Center for Animal Life Science, Nippon Veterinary and Life Science University, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2022,2,11]]},"reference":[{"key":"bibr1-20551169221074240","unstructured":"Valli VE, Jacobs RM, Parodi AL, et al.
