Onychoscopy, a noninvasive tool, might obviate the need for nail biopsy, which is a diagnostic gold standard. &lt;b&gt;&lt;i&gt;Objective:&lt;\/i&gt;&lt;\/b&gt; The aim of this study was to evaluate onychoscopic features of nail unit in patients with nail psoriasis. &lt;b&gt;&lt;i&gt;Methods:&lt;\/i&gt;&lt;\/b&gt;  Fifty-five patients with clinically diagnosed and histologically documented nail psoriasis were recruited. Onychoscopy was performed for each nail (excluding the 5th toenail). Clinically, 443\/550 fingernails and 101\/440 toenails were involved. The frequency distributions of various onychoscopic features was assessed and compared using the \u03c7&lt;sup&gt;2&lt;\/sup&gt; test (&lt;i&gt;p&lt;\/i&gt; value &amp;#x3c;0.05 was considered significant). &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; With onychoscopy, additional 52 fingernails and 64 toenails showed psoriatic involvement. Pitting was the commonest finding in fingernails (60.5%) followed by subungual hyperkeratosis (SUH) (52.8%), onycholysis (40.8%), and dotted capillaries in hyponychium, proximal, and lateral nail folds (38.6 vs. 35.8 vs. 35.8%). In toenails, we observed SUH (85.1%), nail plate thickening (82.1%), onycholysis (77.2%), and dotted capillaries in hyponychium and nail folds (59.4 vs. 53.4 vs. 45.5%). Fuzzy lunula was a novel onychoscopic finding noted in 33.6% fingernails and 4.95% toenails (&lt;i&gt;p&lt;\/i&gt; &amp;#x3c; 0.00001). &lt;b&gt;&lt;i&gt;Limitations:&lt;\/i&gt;&lt;\/b&gt; Small sample size. &lt;b&gt;&lt;i&gt;Conclusions:&lt;\/i&gt;&lt;\/b&gt; Onychoscopy may aid in diagnosing nail lesions even before the clinical signs are apparent. <\/jats:p>","DOI":"10.1159\/000508165","type":"journal-article","created":{"date-parts":[[2020,6,11]],"date-time":"2020-06-11T21:00:33Z","timestamp":1591909233000},"page":"207-215","source":"Crossref","is-referenced-by-count":29,"title":["Dermoscopic Features of Nail Psoriasis: An Observational, Analytical Study"],"prefix":"10.1159","volume":"6","author":[{"given":"Ankita","family":"Chauhan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Archana","family":"Singal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chander","family":"Grover","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sonal","family":"Sharma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2020,6,11]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1038\/sj.jid.5700118"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.4103\/0378-6323.72443"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-3083.2009.03364.x"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/keh198"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2230.2000.00663.x"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.2165\/11318180-000000000-00000"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2005.07.073"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.4103\/0019-5154.135470"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2133.2005.06862.x"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-4632.2004.02335.x"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.4103\/0019-5154.156377"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.5114\/ada.2017.65618"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2007.11.026"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.4103\/idoj.IDOJ_51_19"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.4103\/ijdvl.IJDVL_795_16"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2013.02.009"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-3083.2011.04289.x"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.15386\/cjmed-679"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1111\/1346-8138.13752"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1590\/abd1806-4841.20153736"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2007.07.042"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.3109\/09546634.2011.607796"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2010.10.021"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1684\/ejd.2014.2399"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1007\/s10227-002-0143-0"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-4362.2003.01802.x"},{"key":"ref27","doi-asserted-by":"publisher","DOI":"10.1111\/jdv.14141"},{"key":"ref28","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2133.2000.03544.x"},{"key":"ref29","doi-asserted-by":"publisher","DOI":"10.1159\/000250060"},{"key":"ref30","doi-asserted-by":"publisher","DOI":"10.3109\/03009748109095307"}],"container-title":["Skin Appendage Disorders"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/508165","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/508165","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T16:07:31Z","timestamp":1745424451000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000508165"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020]]},"references-count":30,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2020,7,17]]},"published-print":{"date-parts":[[2020,7,15]]}},"URL":"https:\/\/doi.org\/10.1159\/000508165","archive":["Portico"],"relation":{},"ISSN":["2296-9195","2296-9160"],"issn-type":[{"value":"2296-9195","type":"print"},{"value":"2296-9160","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020]]}}}
