This lesion then extended to the abdomen, arms and legs. From the patient\u2019s back, we found irregular linear hyperpigmented patches with some of the edges in the form of hyperpigmented plaques. On the abdomen, arms and legs, erythema-hyperpigmented plaque and patches were visible along the elevated edges with multiple scattered sizes. Lichen planus (LP) has several types based on various clinical manifestations. The diagnosis of LP can be made based on the clinical appearance and symptoms of pruritus. Many diseases can mimic other diseases so histopathology is used to make the diagnosis. Here, we report a case of LP with unusual features with diagnosis confirmed by histopathological examination. The patient was treated with oral and topical potent corticosteroids with good response.<\/jats:p>","DOI":"10.1136\/bcr-2021-242466","type":"journal-article","created":{"date-parts":[[2021,7,8]],"date-time":"2021-07-08T11:55:53Z","timestamp":1625745353000},"page":"e242466","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Case of lichen planus with unusual features"],"prefix":"10.1136","volume":"14","author":[{"given":"Flandiana","family":"Yogianti","sequence":"first","affiliation":[{"name":"Department of Dermatology and Venereology, Faculty of Medicine, Public Health and Nursing, Universitas Gadjah Mada, Yogyakarta, Daerah Istimewa Yogyakarta, Indonesia"},{"name":"Department of Dermatology and Venereology, Dr. Sardjito General Hospital, Yogyakarta, Daerah Istimewa Yogyakarta, Indonesia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nabila Kirtti","family":"Pradipta","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Venereology, Faculty of Medicine, Public Health and Nursing, Universitas Gadjah Mada, Yogyakarta, Daerah Istimewa Yogyakarta, Indonesia"},{"name":"Department of Dermatology and Venereology, Dr. Sardjito General Hospital, Yogyakarta, Daerah Istimewa Yogyakarta, Indonesia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,7,8]]},"reference":[{"key":"2025082801593060000_14.7.e242466.1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1155\/2014\/742826","article-title":"Cutaneous and mucosal lichen planus: a comprehensive review of clinical subtypes, risk factors, diagnosis, and prognosis","volume":"2014","author":"Gorouhi","year":"2014","journal-title":"ScientificWorldJournal"},{"key":"2025082801593060000_14.7.e242466.2","doi-asserted-by":"crossref","first-page":"39","DOI":"10.5826\/dpc.0604a09","article-title":"Atypical case of lichen planus recognized by dermoscopy","volume":"6","author":"Papageorgiou","year":"2016","journal-title":"Dermatol Pract Concept"},{"key":"2025082801593060000_14.7.e242466.3","doi-asserted-by":"crossref","first-page":"61","DOI":"10.9790\/0853-1216169","article-title":"Lichen planus \u2013A review","volume":"12","author":"Madalli","year":"2013","journal-title":"IOSR-JDMS"},{"key":"2025082801593060000_14.7.e242466.4","doi-asserted-by":"crossref","first-page":"1153","DOI":"10.5005\/jp-journals-10024-2191","article-title":"Oral manifestation in patients diagnosed with dermatological diseases","volume":"18","author":"Thete","year":"2017","journal-title":"J Contemp Dent Pract"},{"key":"2025082801593060000_14.7.e242466.5","first-page":"e1","article-title":"Cutaneous, genital and oral lichen planus: a descriptive study of 274 patients","volume":"24","author":"Cassol-Spanemberg","year":"2019","journal-title":"Med Oral Patol Oral Cir Bucal"},{"key":"2025082801593060000_14.7.e242466.6","doi-asserted-by":"crossref","first-page":"90","DOI":"10.18689\/mjdr-1000123","article-title":"Atypical case of hypertrophic lichen planus recognized by dermoscopy","volume":"4","author":"Zinoune","year":"2019","journal-title":"Madridge J Dermatol Res"},{"key":"2025082801593060000_14.7.e242466.7","first-page":"1","article-title":"An atypical presentation of lichen planus-like reaction from pembrolizumab","volume":"2019","author":"Lee","year":"2019","journal-title":"Case Rep Dermatol Med"},{"key":"2025082801593060000_14.7.e242466.8","doi-asserted-by":"crossref","first-page":"20","DOI":"10.1016\/j.dsi.2016.09.002","article-title":"Atypical dermoscopic findings in patients diagnosed with lichen planus by histological examination","volume":"35","author":"Jung","year":"2017","journal-title":"Dermatologica Sinica"},{"key":"2025082801593060000_14.7.e242466.9","unstructured":"Arnold DL , Krishnamurthy K .
