The mural subtype is characterized by ameloblastomatous epithelial infiltration of the fibrous cyst wall and may demonstrate more aggressive biological behavior than other unicystic variants. This report describes a mural unicystic ameloblastoma in a 62\u2010year\u2010old male presenting with a long\u2010standing painless swelling of the left mandible. Cone\u2010beam computed tomography demonstrated a well\u2010defined radiolucent lesion measuring approximately 47 \u00d7 25\u2009mm with marked buccolingual expansion, internal septations producing a multiloculated appearance, and focal buccal cortical perforation. Incisional biopsy established the diagnosis of ameloblastoma without definitive subclassification. Segmental mandibular resection was subsequently performed because of the lesion\u2032s radiographic extent and cortical perforation. Histopathological examination of the resected specimen demonstrated a true cystic lesion lined by ameloblastomatous odontogenic epithelium with extensive intraluminal plexiform epithelial proliferation and multiple ameloblastomatous epithelial islands infiltrating the fibrous cyst wall, confirming mural unicystic ameloblastoma. Despite these findings, preservation of the underlying cystic architecture supported the diagnosis of mural unicystic ameloblastoma rather than predominantly solid ameloblastoma with secondary cystic degeneration. This case highlights the diagnostic challenges of unicystic ameloblastoma in lesions demonstrating multiloculated radiographic appearance, cortical perforation, and extensive intraluminal and mural proliferation, and emphasizes the importance of adequate histopathological sampling and clinicopathological correlation for accurate subclassification and surgical management.<\/jats:p>","DOI":"10.1155\/crid\/2912131","type":"journal-article","created":{"date-parts":[[2026,7,9]],"date-time":"2026-07-09T08:08:26Z","timestamp":1783584506000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Mural Unicystic Ameloblastoma in a 62\u2010Year\u2010Old Patient Mimicking Conventional Ameloblastoma: A Case Report"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6888-0639","authenticated-orcid":false,"given":"Faisal Mehsen","family":"Alali","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-2297-8122","authenticated-orcid":false,"given":"Maya","family":"Al-jokhadar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad","family":"Al-Qudsi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4021-8552","authenticated-orcid":false,"given":"Ali","family":"Alrafedah","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-3913-1136","authenticated-orcid":false,"given":"Mohammed","family":"Alshammari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3579-1813","authenticated-orcid":false,"given":"Yousef","family":"Alkhaibari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6029-0439","authenticated-orcid":false,"given":"Bassel","family":"Tarakji","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,9]]},"reference":[{"key":"e_1_2_13_1_2","doi-asserted-by":"publisher","DOI":"10.1111\/odi.12646"},{"key":"e_1_2_13_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.joms.2017.03.034"},{"key":"e_1_2_13_3_2","doi-asserted-by":"publisher","DOI":"10.5146\/tjpath.2022.01573"},{"key":"e_1_2_13_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1368-8375(98)00012-8"},{"key":"e_1_2_13_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.bjps.2024.07.042"},{"key":"e_1_2_13_6_2","doi-asserted-by":"publisher","DOI":"10.3390\/reports7040093"},{"key":"e_1_2_13_7_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12105-021-01307-7"},{"key":"e_1_2_13_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.bjoms.2021.07.022"},{"key":"e_1_2_13_9_2","doi-asserted-by":"publisher","DOI":"10.1111\/odi.13031"},{"key":"e_1_2_13_10_2","volume-title":"Oral and Maxillofacial Pathology","author":"Neville B.
