Previous reports of drug\u2010induced acanthosis nigricans have simply consisted of a list of drugs possibly implicated in causing acanthosis nigricans. Several drugs listed are based on single case reports without biopsy confirmation, report of clearing on stopping the drug or reporting on whether acanthosis nigricans recurred with drug rechallenge. A comprehensive literature search was conducted using PubMed, EMBASE(Ovid), Cochrane Library, Scopus, and Web of Science electronic databases. The authors screened the initial result of the search strategy by title and abstract using the following inclusion criteria: eligible studies included those with patients who developed acanthosis nigricans secondary to a drug. This study is the first to comprehensively review the drugs that have been implicated in the development of acanthosis nigricans. A total of 38 studies were included in the systematic review, and a total of 13 acanthosis nigricans inducing drugs were identified. Nicotinic acid and insulin were the two most significant drugs that were reported to cause acanthosis nigricans. By using the results of this study, we created a revised classification system of drug\u2010induced acanthosis nigricans which can be used as a concise framework for clinicians to refer to.<\/jats:p>","DOI":"10.1111\/dth.14794","type":"journal-article","created":{"date-parts":[[2021,1,22]],"date-time":"2021-01-22T01:29:50Z","timestamp":1611278990000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Drug\u2010induced acanthosis nigricans: A systematic review and new classification"],"prefix":"10.1155","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0575-1773","authenticated-orcid":false,"given":"Ahmed I.","family":"Mourad","sequence":"first","affiliation":[{"name":"Department of Medicine, Cumming School of Medicine University of Calgary  Calgary Alberta Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5885-2594","authenticated-orcid":false,"given":"Richard M.","family":"Haber","sequence":"additional","affiliation":[{"name":"Department of Medicine, Cumming School of Medicine University of Calgary  Calgary Alberta Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,2,4]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0190-9622(94)70128-8"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-151-4-200908180-00135"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.2165\/00002018-200528120-00010"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1159\/000246834"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.1959.00270050105016"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.1961.03620050005002"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1001\/archderm.1964.01590260060010"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0190-9622(81)80131-4"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.5070\/D34GD131PK"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2133.1992.tb00692.x"},{"issue":"8","key":"e_1_2_7_12_1","first-page":"739","article-title":"Acanthosis nigricans induced by local nicotinic acid","volume":"111","author":"Pascal J","year":"1984","journal-title":"Ann Dermatol Venereol"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005792-196801000-00002"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1001\/archderm.1984.01650460021010"},{"issue":"2","key":"e_1_2_7_15_1","first-page":"E20","article-title":"Localized acanthosis nigricans at the site of repetitive insulin injections","volume":"105","author":"Bomar L","year":"2020","journal-title":"Cutis"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcjd.2019.08.010"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1503\/cmaj.180705"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1097\/DAD.0000000000000659"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.5070\/D31W06W6RG"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2230.2012.04373.x"},{"issue":"1","key":"e_1_2_7_21_1","first-page":"5","article-title":"Case of exogenous insulin\u2010derived acanthosis nigricans caused by insulin injections","volume":"39","author":"Yahagi E","year":"2014","journal-title":"Tokai J Exp Clin Med"},{"key":"e_1_2_7_22_1","doi-asserted-by":"publisher","DOI":"10.4103\/0378-6323.113112"},{"issue":"12","key":"e_1_2_7_23_1","first-page":"e85","article-title":"Case report: acanthosis nigricans resulting from repetitive same\u2010site insulin injections","volume":"11","author":"Brodell JD","year":"2012","journal-title":"J Drugs Dermatol"},{"key":"e_1_2_7_24_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.diabres.2011.07.023"},{"issue":"4","key":"e_1_2_7_25_1","first-page":"514","article-title":"Visual vignette.
