We report 3 cases through which we will detail the anatomo-clinical characteristics of these tumors. &lt;b&gt;&lt;i&gt;Cases:&lt;\/i&gt;&lt;\/b&gt; Two patients, 60 and 56 years old, consulted for multiple scalp nodules, one of which had changed with the appearance of a central ulceration. The removal of the remaining scalp nodules was in favor of PTCs. The third patient presented with an ulcerative lesion occupying the vertex. Skin biopsy found trichilemmal-type keratinization associated with areas of necrosis concluding with a MPTC. &lt;b&gt;&lt;i&gt;Discussion:&lt;\/i&gt;&lt;\/b&gt; The PTC is a transitional form between the trichilemmal cyst (TC) and the MPTC. The increase in the size of a TC and ulceration are sufficient signals to suspect this evolution. <\/jats:p>","DOI":"10.1159\/000518354","type":"journal-article","created":{"date-parts":[[2021,10,19]],"date-time":"2021-10-19T21:04:47Z","timestamp":1634677487000},"page":"161-164","source":"Crossref","is-referenced-by-count":9,"title":["The Proliferating and Malignant Proliferating Trichilemmal Cyst: An Anatomo-Clinical Study of Three Cases"],"prefix":"10.1159","volume":"8","author":[{"given":"Ibtissam","family":"Benslimane Kamal","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fouzia","family":"Hali","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Farida","family":"Marnissi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soumiya","family":"Chiheb","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2021,10,19]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1001\/archderm.1966.01600250017002"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1097\/RLU.0000000000000742"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.annpat.2011.05.011"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1155\/2016\/7481569"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1159\/000249868"}],"container-title":["Skin Appendage Disorders"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/518354","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/518354","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:14:39Z","timestamp":1745421279000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000518354"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,10,19]]},"references-count":5,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2022,3,3]]},"published-print":{"date-parts":[[2022,3,8]]}},"URL":"https:\/\/doi.org\/10.1159\/000518354","archive":["Portico"],"relation":{},"ISSN":["2296-9195","2296-9160"],"issn-type":[{"value":"2296-9195","type":"print"},{"value":"2296-9160","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,10,19]]}}}
