Furthermore, in the light of already suggested triggers and pathophysiological mechanisms correlating pigmented purpuric dermatosis with various forms of secondary immunodeficiency, we complete our case descriptions by the proposal of a new putative aetiopathogenic actor that would likely account for the occurrence of the clinical association described.<\/jats:p>","DOI":"10.57187\/3993","type":"journal-article","created":{"date-parts":[[2026,2,3]],"date-time":"2026-02-03T08:20:15Z","timestamp":1770106815000},"page":"3993","source":"Crossref","is-referenced-by-count":0,"title":["Pigmented purpuric dermatosis in two patients with common variable immunodeficiency"],"prefix":"10.57187","volume":"156","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-6922-1204","authenticated-orcid":false,"given":"Vincenzo","family":"Papa","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alessandra","family":"Bennici","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3105-8347","authenticated-orcid":false,"given":"Luisa","family":"Ricciardi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paolina","family":"Quattrocchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sebastiano","family":"Gangemi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paola Lucia","family":"Minciullo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"36756","published-online":{"date-parts":[[2026,1,28]]},"container-title":["Swiss Medical Weekly"],"original-title":[],"link":[{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/3993\/6533","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/3993\/6534","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/3993\/6533","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,2,3]],"date-time":"2026-02-03T14:53:19Z","timestamp":1770130399000},"score":1,"resource":{"primary":{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/view\/3993"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,1,28]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2026,1,1]]}},"URL":"https:\/\/doi.org\/10.57187\/3993","relation":{},"ISSN":["1424-3997"],"issn-type":[{"value":"1424-3997","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1,28]]}}}
