Due to its extensive use, there is an inherent risk of developing a contact allergy to it. Previous studies have shown that the prevalence rate of contact allergy to colophonium is around 1%\u20132%. This meta\u2010analysis aimed to estimate the current prevalence of colophonium contact allergy in dermatitis patients. Two authors independently searched PubMed, Embase and Web of Science for studies reporting the prevalence of contact allergy in dermatitis patients with inception through 30 June 2025. A proportion meta\u2010analysis was conducted to estimate the pooled prevalence of colophonium contact allergy. Seventy\u2010three studies involving 459\u2009757 patients with dermatitis were included. The pooled prevalence of colophonium contact allergy was 3.54% (95% CI, 3.01\u20134.16) with an\n                    <jats:italic>I<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    of 98.6% (95% CI, 98.5\u201398.7) and a clinical relevance of 39.42% (95% CI, 37.94\u201340.92). Significant sensitization rates were observed in different geographic regions, with the highest prevalence found in Southeast Asia (6.83%). The prevalence rate was 3.31% among children and 1.31% among adults; however, these differences were not statistically significant. The prevalence rate was 4.74% for patients with AD and 4.87% for patients without AD, with no statistically significant difference. Colophonium sensitization has remained stable in recent decades, highlighting the substance's widespread presence in products. This emphasizes the need for prevention and better registration.\n                  <\/jats:p>","DOI":"10.1111\/cod.70153","type":"journal-article","created":{"date-parts":[[2026,4,5]],"date-time":"2026-04-05T23:14:06Z","timestamp":1775430846000},"page":"1-16","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Prevalence of Contact Allergy to Colophonium in Dermatitis Patients: A Systematic Review and Meta\u2010Analysis"],"prefix":"10.1111","volume":"95","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-1580-4671","authenticated-orcid":false,"given":"Kian","family":"Karimian","sequence":"first","affiliation":[{"name":"National Allergy Research Centre, Department of Dermatology and Allergy Herlev and Gentofte Hospital  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-2780-3604","authenticated-orcid":false,"given":"Daniel","family":"Isufi","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Allergy Herlev and Gentofte\u2014Copenhagen University Hospital  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2442-5735","authenticated-orcid":false,"given":"Mikkel Bak","family":"Jensen","sequence":"additional","affiliation":[{"name":"National Allergy Research Centre, Department of Dermatology and Allergy Herlev and Gentofte Hospital  Copenhagen Denmark"},{"name":"Institute of Clinical Medicine, Faculty of Health and Medical Sciences, University of Copenhagen  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3537-8463","authenticated-orcid":false,"given":"Jeanne Duus","family":"Johansen","sequence":"additional","affiliation":[{"name":"National Allergy Research Centre, Department of Dermatology and Allergy Herlev and Gentofte Hospital  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-9756-656X","authenticated-orcid":false,"given":"Jakob Ferl\u00f8v Baselius","family":"Schwensen","sequence":"additional","affiliation":[{"name":"National Allergy Research Centre, Department of Dermatology and Allergy Herlev and Gentofte Hospital  Copenhagen Denmark"},{"name":"Institute of Clinical Medicine, Faculty of Health and Medical Sciences, University of Copenhagen  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,4,5]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/J.1600\u20100536.1999.TB06178.X"},{"key":"e_1_2_12_3_1","volume-title":"Kanerva's Occupational Dermatology","author":"Karlberg A.
