This was carried out on paraffin-embedded specimens using an unlabelled antibody peroxidase-antiperoxidase method. In all lesions IgG-producing plasma cells predominated. IgA- and IgD-positive cells were also present in about equal quantities but fewer than IgG. IgM-positive cells were either absent or present in very low numbers. Especially in erosive lesions a high number of plasma cells was noticed. The \u03ba\/\u03bb ratio was variable with a preference for \u03bb in 5 of 8 cases. These findings are suggestive of a nonspecific polyclonal stimulation of B cells, which might be caused by a persistent infection. The above-mentioned findings were compared with premalignant and malignant skin lesions in which a major amount of plasma cells was present in the inflammatory infiltrate. Comparable results were obtained with slight variations. The role of plasma cells in these infiltrates is discussed.<\/jats:p>","DOI":"10.1159\/000249302","type":"journal-article","created":{"date-parts":[[2009,10,21]],"date-time":"2009-10-21T09:50:36Z","timestamp":1256118636000},"page":"77-81","source":"Crossref","is-referenced-by-count":21,"title":["Immunohistochemical Characterization of Plasma Cells in Zoon\u2019s Balanoposthitis and (Pre)malignant Skin Lesions"],"prefix":"10.1159","author":[{"given":"J.","family":"Toonstra","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.F.","family":"van Wichen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,10,13]]},"container-title":["Dermatologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/249302","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000249302","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T09:36:47Z","timestamp":1777541807000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000249302"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,10,13]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000249302","archive":["Portico"],"relation":{},"ISSN":["0011-9075","2571-7197"],"issn-type":[{"value":"0011-9075","type":"print"},{"value":"2571-7197","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,10,13]]}}}
