Over recent years, the genetic characterization of such neoplasms has enabled the identification of several new tumour entities. Among such emerging skin tumours, it is noteworthy that the majority harbour phenotypic and molecular similarities with entities already well established in other organs. Notably, over the last decade, several sweat gland tumours analogous to neoplasms of the salivary glands have been reported. More recently, among poorly differentiated skin carcinomas, several distinctive tumour entities defined by recurrent genetic alterations previously reported in other organs notably the lung have been identified. Finally, a couple of recurrent oncogenic events not previously described in other organs have recently been documented in skin epithelial tumours allowing for the refinement of the diagnostic criteria of established tumour entities and the identification of novel ones. In the present review, we aim to provide an overview of the main emerging skin epithelial tumours, with particular emphasis on what the field of dermatopathology can learn from the oncogenic mechanisms already identified in other organs.<\/jats:p>","DOI":"10.1111\/his.70245","type":"journal-article","created":{"date-parts":[[2026,8,3]],"date-time":"2026-08-03T06:24:44Z","timestamp":1785738284000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Novel and emerging skin carcinomas and adnexal tumours"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2201-6914","authenticated-orcid":false,"given":"Thibault","family":"Kervarrec","sequence":"first","affiliation":[{"name":"Department of Pathology, Centre Hospitalier Universitaire de Tours Universit\u00e9 de Tours  Tours France"},{"name":"CARADERM Network  France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7053-7431","authenticated-orcid":false,"given":"Maxime","family":"Battistella","sequence":"additional","affiliation":[{"name":"CARADERM Network  France"},{"name":"Institut de Recherche Saint Louis (IRSL) Universit\u00e9 Paris Cit\u00e9, Inserm 1342  Paris France"},{"name":"Service de Pathologie, AP\u2010HP,\u00a0H\u00f4pital Saint\u2010Louis  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9882-2162","authenticated-orcid":false,"given":"Nicolas","family":"Macagno","sequence":"additional","affiliation":[{"name":"CARADERM Network  France"},{"name":"Service de Pathologie, AP\u2010HP,\u00a0H\u00f4pital Saint\u2010Louis  Paris France"},{"name":"Department of Pathology Timone University Hospital  Marseille France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,2]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"crossref","first-page":"e52","DOI":"10.1016\/S1470-2045(15)00386-1","article-title":"Rare cancers: a sea of opportunity","volume":"17","author":"Boyd N","year":"2016","journal-title":"Lancet Oncol."},{"key":"e_1_2_13_3_1","doi-asserted-by":"crossref","first-page":"976","DOI":"10.1016\/j.jid.2019.09.026","article-title":"Polyomavirus\u2010positive Merkel cell carcinoma derived from a Trichoblastoma suggests an epithelial origin of this Merkel cell carcinoma","volume":"140","author":"Kervarrec T","year":"2020","journal-title":"J.
