These diseases may present as purplish, reddish\u2010brown cutaneous plaques or nodules. Here, we report an exceptional case of lichen planus (LP) in which the patient had classic histopathological features, but the infiltrating inflammatory cells were plasma cells with restricted light chain expression. The patient presented with severe rashes, including purplish\u2010red plaques and nodules, erythema, and erosions in the palmoplantar area, verrucous hyperplasia of the oral mucosa, and anonychia of the toes. These findings suggest a possible role of plasma cells with restricted light chain expression in the LP. Clinicians should closely follow patients for changes in their rash, perform repeat biopsies if necessary, and regularly conduct multisystemic evaluations.<\/jats:p>","DOI":"10.1111\/cup.14699","type":"journal-article","created":{"date-parts":[[2024,8,10]],"date-time":"2024-08-10T02:39:30Z","timestamp":1723257570000},"page":"938-941","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Widespread purplish\u2010red plaques with plasma cell infiltrate: A rare type of lichen planus"],"prefix":"10.1111","volume":"51","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0013-2815","authenticated-orcid":false,"given":"Szeman","family":"Cheung","sequence":"first","affiliation":[{"name":"Department of Dermatology, Ruijin Hospital Shanghai Jiao Tong University School of Medicine  Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7961-6427","authenticated-orcid":false,"given":"Jie","family":"Zheng","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Ruijin Hospital Shanghai Jiao Tong University School of Medicine  Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9232-1412","authenticated-orcid":false,"given":"Xiaoqing","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Ruijin Hospital Shanghai Jiao Tong University School of Medicine  Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,8,9]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMcp1103641"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000372\u2010199406000\u201000015"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600\u20100560.2007.00965.x"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1001\/archderm.127.2.264"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/DAD.0000000000000706"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/DAD.0000000000002109"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/s0190\u20109622(97)70046\u2010x"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2012.11.031"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/cam4.4816"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2009.07.047"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clml.2011.07.004"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1177\/0022034518788282"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365\u20102133.2000.03303.x"}],"container-title":["Journal of Cutaneous Pathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/cup.14699","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,11,4]],"date-time":"2024-11-04T08:07:35Z","timestamp":1730707655000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/cup.14699"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,8,9]]},"references-count":13,"journal-issue":{"issue":"12","published-print":{"date-parts":[[2024,12]]}},"alternative-id":["10.1111\/cup.14699"],"URL":"https:\/\/doi.org\/10.1111\/cup.14699","archive":["Portico"],"relation":{},"ISSN":["0303-6987","1600-0560"],"issn-type":[{"type":"print","value":"0303-6987"},{"type":"electronic","value":"1600-0560"}],"subject":[],"published":{"date-parts":[[2024,8,9]]},"assertion":[{"value":"2023-12-14","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-07-23","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-08-09","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
