Objective: Confirm the beneficial effect of low doses of oral tretinoin in lichen planus. Methods: Eighteen patients with lichen planus were treated in an open study for up to 19 months. Efficacy and safety data were recorded. Results: Complete remission was observed in 13 (72%) and marked improvement in 4 (22%) out of 18 patients. Six patients showed moderate and 12 had no side effects. Conclusion: Tretinoin is a valuable drug when given at low doses to patients with lichen planus who failed to respond to other therapies.<\/jats:p>","DOI":"10.1159\/000246406","type":"journal-article","created":{"date-parts":[[2009,10,7]],"date-time":"2009-10-07T07:08:20Z","timestamp":1254899300000},"page":"334-336","source":"Crossref","is-referenced-by-count":26,"title":["Efficacy of Oral Low-Dose Tretinoin (all-trans-Retinoic Acid) in Lichen planus"],"prefix":"10.1159","author":[{"given":"F.","family":"Ott","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W.","family":"Bollag","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.-M.","family":"Geiger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,10,7]]},"container-title":["Dermatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/246406","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000246406","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T09:16:14Z","timestamp":1777540574000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000246406"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,10,7]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000246406","archive":["Portico"],"relation":{},"ISSN":["1018-8665","1421-9832"],"issn-type":[{"value":"1018-8665","type":"print"},{"value":"1421-9832","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,10,7]]}}}
