A 66\u2010year\u2010old man was admitted to our hospital with right\u2010dominant bilateral pleural effusions and gradually worsening dyspnoea. Chest radiographs revealed right\u2010dominant pleural effusions, while chest computed tomography showed bilateral pleural effusions without parenchymal lesions. Although the bilateral pleural effusions were exudative with an increased number of lymphocytes, the definitive diagnosis was initially elusive. High IgG4 levels in the serum and pleural effusions were observed. A pathological evaluation of a right pleural biopsy specimen collected via video\u2010assisted thoracoscopic surgery showed fibrosis\u2010associated lymphoplasmacytic infiltration, 45\u201360 IgG4\u2010positive plasma cells per high\u2010power field, and an IgG4\/immunoglobulin G ratio of 40%. Consequently, the patient was diagnosed with IgG4\u2010related pleural disease. The bilateral pleural effusions improved after corticosteroid therapy.<\/jats:p>","DOI":"10.1002\/rcr2.1442","type":"journal-article","created":{"date-parts":[[2024,7,31]],"date-time":"2024-07-31T06:25:38Z","timestamp":1722407138000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["<scp>IgG4<\/scp>\u2010related pleural disease diagnosed by thoracoscopic pleural biopsy: A case report"],"prefix":"10.1002","volume":"12","author":[{"given":"Azusa","family":"Miyoshi","sequence":"first","affiliation":[{"name":"Department of Respiratory Medicine Tokyo Women's Medical University  Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9180-7605","authenticated-orcid":false,"given":"Hideki","family":"Katsura","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine Tokyo Women's Medical University  Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0045-1720","authenticated-orcid":false,"given":"Tomohiro","family":"Akaba","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine Tokyo Women's Medical University  Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mitsuko","family":"Kondo","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine Tokyo Women's Medical University  Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Etsuko","family":"Tagaya","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine Tokyo Women's Medical University  Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,7,30]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra1104650"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/MCP.0000000000000581"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.resinv.2023.06.009"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.rmcr.2020.101019"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/cei.12999"}],"container-title":["Respirology Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/rcr2.1442","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,8,27]],"date-time":"2024-08-27T11:29:36Z","timestamp":1724758176000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/rcr2.1442"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,7,30]]},"references-count":5,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2024,8]]}},"alternative-id":["10.1002\/rcr2.1442"],"URL":"https:\/\/doi.org\/10.1002\/rcr2.1442","archive":["Portico"],"relation":{},"ISSN":["2051-3380","2051-3380"],"issn-type":[{"type":"print","value":"2051-3380"},{"type":"electronic","value":"2051-3380"}],"subject":[],"published":{"date-parts":[[2024,7,30]]},"assertion":[{"value":"2024-05-21","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-07-22","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-07-30","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e01442"}}
