However, it has been under-utilized for the diagnosis and characterization of mucosal disorders. The dermoscopic characterization of cutaneous lichen planus and its variants has been well documented with Wickham\u2019s striae constituting the hallmark of the condition. However, the dermoscopic features of oral lichen planus with hand-held or videodermoscopy remain to be elucidated. We present the case of a young adult man who presented with asymptomatic white lacy lesions over a bluish-black background over the tongue, patchy hyperpigmentation of the buccal mucosae and gingivae, and longitudinal melanonychia involving some nails. History of intake of any drugs preceding the lesions, smoking, chewing of betel nut and dental implants was negative. Family history was non-contributory. There were no cutaneous lesions suggestive of lichen planus. Mucoscopy (dermoscopy of the mucosa, oral in this case) and onychoscopy were done followed by biopsy from the tongue that confirmed the diagnosis of lichen planus. Oral mucoscopy of the tongue revealed a tri-colored pattern with structureless veil-like grey-white areas (modified Wickham\u2019s striae), well-demarcated red glossy erosions, and violaceous-to-brown clods. Additionally, vascular pattern of dotted and linear to curved vessels along the borders of leukoplakia-like areas and erosions were observed. Onychoscopy confirmed lichen planus-associated melanonychia. Dermoscopy also proved useful in conveniently ruling out other disorders typified by mucosal and nail pigmentation such as Laugier Hunziker syndrome and drug-induced changes. Although direct oral microscopy has been used in defining features of oral lichen planus, to the best of our knowledge this case is the first report on mucoscopy or dermoscopy of oral lichen planus<\/ns4:p>","DOI":"10.12688\/f1000research.14134.2","type":"journal-article","created":{"date-parts":[[2018,3,27]],"date-time":"2018-03-27T09:25:02Z","timestamp":1522142702000},"page":"284","update-policy":"https:\/\/doi.org\/10.12688\/f1000research.crossmark-policy","source":"Crossref","is-referenced-by-count":11,"title":["Case Report: Dermoscopic features of oral lichen planus - the evolution of mucoscopy"],"prefix":"10.12688","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7444-4956","authenticated-orcid":false,"given":"Sidharth","family":"Sonthalia","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sangeeta","family":"Varma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abhijeet Kumar","family":"Jha","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deepak","family":"Jakhar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feroze","family":"Kaliyadan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2560","published-online":{"date-parts":[[2018,3,27]]},"reference":[{"key":"ref-1","doi-asserted-by":"publisher","first-page":"679-94","DOI":"10.1016\/j.det.2013.06.008","article-title":"Dermoscopy in general dermatology.","volume":"31","author":"A Lallas","year":"2013","journal-title":"Dermatol Clin."},{"key":"ref-2","doi-asserted-by":"publisher","first-page":"151-6","DOI":"10.1159\/000071785","article-title":"Dermoscopic features of plaque psoriasis and lichen planus: new observations.","volume":"207","author":"F V\u00e1zquez-L\u00f3pez","year":"2003","journal-title":"Dermatology."},{"key":"ref-3","doi-asserted-by":"publisher","first-page":"808","DOI":"10.1001\/archderm.142.6.808","article-title":"Dermoscopy subpatterns of inflammatory skin disorders.","volume":"142","author":"I Zalaudek","year":"2006","journal-title":"Arch Dermatol."},{"key":"ref-4","doi-asserted-by":"publisher","first-page":"1130","DOI":"10.1001\/archdermatol.2011.278","article-title":"Dermoscopy for discriminating between lichenoid sarcoidosis and lichen planus.","volume":"147","author":"F Vazquez-Lopez","year":"2011","journal-title":"Arch Dermatol."},{"key":"ref-5","doi-asserted-by":"publisher","first-page":"1198-205","DOI":"10.1111\/j.1365-2133.2012.10868.x","article-title":"Accuracy of dermoscopic criteria for the diagnosis of psoriasis, dermatitis, lichen planus and pityriasis rosea.","volume":"166","author":"A Lallas","year":"2012","journal-title":"Br J Dermatol."},{"key":"ref-6","doi-asserted-by":"publisher","first-page":"593-619","DOI":"10.1016\/0190-9622(91)70241-S","article-title":"Lichen planus.","volume":"25","author":"A Boyd","year":"1991","journal-title":"J Am Acad Dermatol."},{"key":"ref-7","doi-asserted-by":"crossref","first-page":"216-220","DOI":"10.2340\/0001555552216220","article-title":"Prevalence of oral lichen planus among 7639 Indian villagers in Kerala, South India.","volume":"52","author":"J Pindborg","year":"1972","journal-title":"Acta Derm Venereol."},{"key":"ref-8","doi-asserted-by":"crossref","first-page":"255-257","DOI":"10.2340\/0001555559255257","article-title":"Incidence rate of oral lichen planus among Indian villagers.","volume":"59","author":"R Bhonsle","year":"1979","journal-title":"Acta Derm Venereol."},{"key":"ref-9","doi-asserted-by":"publisher","first-page":"79-89","DOI":"10.1016\/S0733-8635(02)00067-0","article-title":"The clinical manifestations and treatment of oral lichen planus.","volume":"21","author":"D Eisen","year":"2003","journal-title":"Dermatol Clin."},{"key":"ref-10","doi-asserted-by":"publisher","first-page":"51-5","DOI":"10.5826\/dpc.0504a13","article-title":"Dermoscopic findings in different clinical variants of lichen planus.
