Diagnosis of LS is mainly clinical, but clinical differentiation from conditions like vitiligo, morphea may be a difficult task at times that often requires histological analysis. Dermoscopy is one such non-invasive tool which can help diagnose the disease. There is paucity of Indian data on dermoscopy of LS.\nObjectives: To evaluate clinical, dermatoscopic patterns of LS and correlate them with histopathology.\nMethods: The study was conducted in a tertiary hospital after obtaining consent from 20 patients. OITEZ e-scope digital microscope was used to evaluate the lesions. Both polarized and nonpolarized mode were used and skin biopsy was done to confirm diagnosis.\nResults: Based on morphology, LS was classified as scleroatrophic lesions (61.5%), guttate lesions (30.8%) and hyperkeratotic lesions (7.7%). Dermoscopic analysis revealed structureless white to yellow areas\u00a0 as most common finding (100%) followed by chrysalis like structure (80.8%). Linear irregular vessels were seen in 61.5% lesions and perifollicular scaling in 50.0% lesions. Keratotic plugs were seen in 50.0% lesions. A new characteristic finding, \u201crosettes\u201d was seen in 38.5% lesions has never been reported with LS before. Non polarized mode was particularly useful for identifying texture changes, keratotic plugs and minute scales which were not visible otherwise.Conclusions: Dermoscopy is a simple diagnostic tool that helps in the early diagnosis of LS with specific pattern which can avoid invasive procedure like biopsy. Both non-polarised and polarized dermoscopy must be done to visualize the changes of LS well.<\/jats:p>","DOI":"10.5826\/dpc.1203a125","type":"journal-article","created":{"date-parts":[[2022,7,29]],"date-time":"2022-07-29T10:03:20Z","timestamp":1659089000000},"page":"e2022125","source":"Crossref","is-referenced-by-count":13,"title":["Dermoscopic evaluation of extragenital lichen sclerosus et atrophicus"],"prefix":"10.5826","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6136-1278","authenticated-orcid":false,"given":"Sunanda Arun","family":"Mahajan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jayati Shailesh","family":"Dave","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"27750","published-online":{"date-parts":[[2022,7,28]]},"container-title":["Dermatology Practical &amp; Conceptual"],"original-title":[],"link":[{"URL":"http:\/\/dpcj.org\/index.php\/dpc\/article\/download\/1854\/1649","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/dpcj.org\/index.php\/dpc\/article\/download\/1854\/1649","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,7,30]],"date-time":"2022-07-30T10:03:27Z","timestamp":1659175407000},"score":1,"resource":{"primary":{"URL":"http:\/\/dpcj.org\/index.php\/dpc\/article\/view\/1854"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,7,28]]},"references-count":0,"URL":"https:\/\/doi.org\/10.5826\/dpc.1203a125","relation":{},"ISSN":["2160-9381"],"issn-type":[{"value":"2160-9381","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,7,28]]}}}
