Excisional biopsy revealed abrupt transition from oral mucosal epithelium to epidermis\u2010like stratified squamous epithelium with hyperkeratosis, hypergranulosis, basal cell melanosis, and mild melanocytic hyperplasia, along with sebaceous adnexal structures in the lamina propria, confirming the diagnosis. Epidermal choristoma is an exceptionally rare developmental lesion of ectodermal origin, with nine oral cases reported to date. Due to its nonspecific clinical appearance, it may be mistaken for benign melanotic lesions or early mucosal melanoma. Complete surgical excision is curative, with no recurrence observed at 15\u2010month follow\u2010up in this case. This report highlights the importance of histopathologic evaluation of pigmented tongue lesions to avoid misdiagnosis and ensure appropriate management.<\/jats:p>","DOI":"10.1155\/crid\/1327746","type":"journal-article","created":{"date-parts":[[2026,9,24]],"date-time":"2026-09-24T11:34:50Z","timestamp":1790249690000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Epidermal Choristoma of the Tongue: A Potential Diagnostic Pitfall"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0239-4619","authenticated-orcid":false,"given":"Rana Saud","family":"Alshagroud","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-5034-7044","authenticated-orcid":false,"given":"Bader Mutrik","family":"Aldawsari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-7083-4539","authenticated-orcid":false,"given":"Hassan Ibrahim","family":"Khormi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yara Ibrahim","family":"Alromaih","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7881-3966","authenticated-orcid":false,"given":"Azizah Bin","family":"Mubayrik","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,24]]},"reference":[{"key":"e_1_2_8_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajoms.2011.11.005"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/0030-4220(91)90498-2"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.joms.2009.04.120"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.12968\/denu.2000.27.5.231"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.0303-6987.2005.00325.x"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcms.2012.02.023"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1111\/pde.12487"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/pde.14589"},{"key":"e_1_2_8_9_2","article-title":"Epidermal Choristoma Presenting as an Enlarging Tongue Mass","volume":"4","author":"Lindquist N.
