Case Representation: In 3 cases, only nodules were observed at the initial presentation, but bullous lesions appeared during the course of the disease. All patients had diabetes mellitus and were taking DPP-4 inhibitors from 1 to 1.5 years. Anti-BP180Nc16a antibodies were positive in 3 cases, and low or negative in 3 cases. Full-length BP180 antibodies were analyzed in 2 of the 6 cases and were positive in both. Since patients with diabetes mellitus occasionally develop prurigo nodularis, it is important not to misdiagnose pemphigoid nodularis as prurigo nodularis. Conclusion: There are few reports of pemphigoid nodularis under DPP-4 inhibitors. It should be noted that not only bullous pemphigoid but also pemphigoid nodularis can be induced by DPP-4 inhibitors. &lt;\/p&gt;<\/jats:p>","DOI":"10.1159\/000552572","type":"journal-article","created":{"date-parts":[[2026,9,29]],"date-time":"2026-09-29T16:01:11Z","timestamp":1790697671000},"page":"675-683","source":"Crossref","is-referenced-by-count":0,"title":["Six Cases of Pemphigoid Nodularis during Treatment with Dipeptidyl Peptidase-4 Inhibitors"],"prefix":"10.1159","volume":"18","author":[{"given":"Natsumi","family":"Norikawa","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Misaki","family":"Kusano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aki","family":"Honda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshiyuki","family":"Yamamoto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2026,9,29]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/s0190-9622(81)70077-x"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.3389\/fimmu.2019.01224"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.3389\/fimmu.2022.885023"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-3083.2011.04062.x"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1111\/ijd.15458"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1111\/1346-8138.16330"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1111\/bjd.18364"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.jdermsci.2013.12.001"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1001\/archdermatol.2011.23"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016\/j.jid.2016.06.622"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1159\/000527913"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1111\/jdi.13676"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.3389\/fimmu.2026.1651543"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.jdcr.2022.12.006"}],"container-title":["Case Reports in Dermatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000552572","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,2]],"date-time":"2026-10-02T07:17:32Z","timestamp":1790925452000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000552572"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,29]]},"references-count":14,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2026,1,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000552572","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.33313365","asserted-by":"subject"}]},"ISSN":["1662-6567"],"issn-type":[{"value":"1662-6567","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,9,29]]}}}
