Occasionally, meningiomas are identified outside the central nervous system, and are referred to as extracranial meningiomas (EMs). The vast majority of EMs are an extension from an intracranial or intraspinal tumor. However, primary EMs may arise from extracranial sites with the most common sites being the skin and scalp subcutis, which are further categorized as cutaneous meningiomas (CMs). CMs are rare cutaneous tumors with similar ultrastructural and cytologic findings compared to those of intracranial meningiomas, but with a wide range of histologic differences. Therefore, an assessment using a panel of investigative tools, including imaging, histopathology, and immunohistochemistry, is required to determine the diagnosis of CMs. Here, we report the case of a 64-year-old gentleman presenting with a posttraumatic well-circumscribed superficial mass overlying the right nasal bridge. We are unable to identify other cases arising in the nasal bridge.<\/jats:p>","DOI":"10.3390\/diagnostics14161731","type":"journal-article","created":{"date-parts":[[2024,8,9]],"date-time":"2024-08-09T09:48:54Z","timestamp":1723196934000},"page":"1731","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Posttraumatic Cutaneous Meningioma with a \u201cMeningiolipoma\u201d Pattern Presenting as a Nasal Bridge Mass"],"prefix":"10.3390","volume":"14","author":[{"given":"Dong","family":"Ren","sequence":"first","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, University of California, Irvine, CA 92697, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jerry","family":"Lou","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, University of California, Irvine, CA 92697, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edward","family":"Kuan","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, University of California, Irvine, CA 92697, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8786-1932","authenticated-orcid":false,"given":"Mari","family":"Perez-Rosendahl","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, University of California, Irvine, CA 92697, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William H.","family":"Yong","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, University of California, Irvine, CA 92697, USA"},{"name":"Department of Pathology, University of California, Irvine Medical Center, Orange, CA 92868, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"ii1","DOI":"10.1093\/neuonc\/not151","article-title":"CBTRUS statistical report: Primary brain and central nervous system tumors diagnosed in the United States in 2006\u20132010","volume":"15","author":"Ostrom","year":"2013","journal-title":"Neuro-oncology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"60","DOI":"10.1111\/his.12366","article-title":"Comparative study of soft tissue perineurioma and meningioma using a five-marker immunohistochemical panel","volume":"65","author":"Agaimy","year":"2014","journal-title":"Histopathology"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"113","DOI":"10.1007\/s12105-010-0177-3","article-title":"Intraoral perineurioma, soft tissue type: Report of five cases, including 3 intraosseous examples, and review of the literature","volume":"4","author":"Koutlas","year":"2010","journal-title":"Head Neck Pathol."},{"key":"ref_4","doi-asserted-by":"crossref","unstructured":"Liu, H., Qian, H., Li, X., Zuo, F., Meng, X., Liu, S., and Wan, J.
