Few studies in the United States (US) have compared the prevalence of BCC to SCC by anatomical location. The aim of this study was to determine the KC prevalence in a Midwestern US population standardised by relative tumour density (RTD) per anatomical area, which has not been previously reported in the US. Data was collected from Veterans Affairs' patients with biopsy\u2010proven KCs from October 1999 to September 2020. KCs were divided into BCCs and SCCs. RTD was calculated by standardising frequency of occurrence in a location by body surface area. The proportion of BCCs to SCCs for each location was also analysed. A total of 31\u2009663 KCs (17\u2009776 BCCs and 13\u2009887 SCCs) were identified in 10\u2009933 patients, with the majority on the head and neck. BCCs were more likely overall on the trunk and upper arms than SCCs. SCCs were more common on the hands, forearms, genitals\/perineum\/perianal area, and ears. Both BCC and SCC occurred more frequently over sun\u2010exposed areas when controlling for body surface area of the location. Higher proportions of BCCs were found on sun\u2010protected areas when compared to SCCs. The relative preponderance of SCCs on the genitals\/perineum\/perianal area may be due to human papillomavirus.<\/jats:p>","DOI":"10.1111\/exd.70196","type":"journal-article","created":{"date-parts":[[2025,12,19]],"date-time":"2025-12-19T12:39:19Z","timestamp":1766147959000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Anatomical Locations of Keratinocyte Carcinomas Among United States Veterans Affairs Healthcare System Patients in Minnesota: A Cross\u2010Sectional Study"],"prefix":"10.1111","volume":"34","author":[{"given":"Mikhail","family":"Usovich","sequence":"first","affiliation":[{"name":"Department of Dermatology Minneapolis VA Medical Health Care System  Minneapolis Minnesota USA"},{"name":"Department of Dermatology University of Minnesota  Minneapolis Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-5336-0309","authenticated-orcid":false,"given":"John","family":"Meisenheimer","sequence":"additional","affiliation":[{"name":"Department of Dermatology Minneapolis VA Medical Health Care System  Minneapolis Minnesota USA"},{"name":"Department of Dermatology University of Minnesota  Minneapolis Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Madeeha","family":"Rizvi","sequence":"additional","affiliation":[{"name":"Department of Dermatology Minneapolis VA Medical Health Care System  Minneapolis Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5086-7679","authenticated-orcid":false,"given":"Katelyn J.","family":"Rypka","sequence":"additional","affiliation":[{"name":"Department of Dermatology Minneapolis VA Medical Health Care System  Minneapolis Minnesota USA"},{"name":"Department of Dermatology University of Minnesota  Minneapolis Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liang","family":"Liu","sequence":"additional","affiliation":[{"name":"The Hormel Institute, University of Minnesota  Minneapolis Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erin M.","family":"Warshaw","sequence":"additional","affiliation":[{"name":"Department of Dermatology Minneapolis VA Medical Health Care System  Minneapolis Minnesota USA"},{"name":"Department of Dermatology University of Minnesota  Minneapolis Minnesota USA"},{"name":"From the Contact Dermatitis Clinic Park Nicollet Health System  Minneapolis Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amy","family":"Gravely","sequence":"additional","affiliation":[{"name":"Department of Research Minneapolis VA Medical Center  Minneapolis Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0108-2127","authenticated-orcid":false,"given":"Julie","family":"Lynch","sequence":"additional","affiliation":[{"name":"VA Informatics and Computing Infrastructure (VINCI), VA Salt Lake City Health Care System  Salt Lake City Utah USA"},{"name":"Division of Epidemiology, Department of Internal Medicine University of Utah School of Medicine  Salt Lake City Utah USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anders D.","family":"Westanmo","sequence":"additional","affiliation":[{"name":"Department of Pharmacy Benefits Services Minneapolis VA Health Care System  Minneapolis Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noah","family":"Goldfarb","sequence":"additional","affiliation":[{"name":"Department of Dermatology Minneapolis VA Medical Health Care System  Minneapolis Minnesota USA"},{"name":"Department of Dermatology University of Minnesota  Minneapolis Minnesota USA"},{"name":"Department of Internal Medicine Minneapolis VA Health Care System  Minneapolis Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,12,19]]},"reference":[{"key":"e_1_2_14_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2012.11.037"},{"key":"e_1_2_14_3_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamadermatol.2015.1187"},{"key":"e_1_2_14_4_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamadermatol.2016.4070"},{"key":"e_1_2_14_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/jso.2930030304"},{"key":"e_1_2_14_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2017.10.007"},{"key":"e_1_2_14_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2017.10.006"},{"key":"e_1_2_14_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0215(19990517)81:4<555::AID-IJC9>3.0.CO;2-R"},{"key":"e_1_2_14_9_1","doi-asserted-by":"publisher","DOI":"10.1067\/mjd.2001.114742"},{"issue":"10","key":"e_1_2_14_10_1","first-page":"1105","article-title":"Changes in Nonmelanoma Skin Cancer Incidence Between 1977\u20101978 and 1998\u20101999 in Northcentral New Mexico","volume":"12","author":"Athas W.
