Additionally, a sebaceous steatocystoma of the anterior scalp presented alongside the meningioma. A steatocystoma localized to the scalp is also remarkably rare. To our knowledge, this is the first report documenting <jats:italic>both<\/jats:italic> an extracranial meningioma and a steatocystoma presenting concurrently on the scalp. A male patient in his thirties presented with a mass lesion on the scalp. A CT scan revealed one posterior scalp mass with no intracranial abnormalities. Post excision histologic examination confirmed an extracranial meningioma (meningothelial variant, WHO Grade I). A second anterior scalp mass, not revealed by CT scan, was discovered during surgery. It was excised and diagnosed as a steatocystoma. Meningiomas predominantly occur intracranially but, in some instances, may present as a standalone extracranial tumor <jats:italic>without<\/jats:italic> intracranial abnormalities. Because extracranial meningioma is uncommon, it may be overlooked during clinical diagnosis of scalp masses. We recommend that this neoplasm be routinely considered in the differential diagnosis of extracranial tumors. The discovery of another rare tumor\u2014a steatocystoma located in immediate proximity on the scalp\u2014is further remarkable. We briefly review relevant case reports and etiologies and consider a potential relationship between the two neoplasms. However, it remains more likely that the concurrence of these tumors in our patient was simply coincidental.<\/jats:p>","DOI":"10.1155\/2020\/6539064","type":"journal-article","created":{"date-parts":[[2020,9,8]],"date-time":"2020-09-08T23:33:50Z","timestamp":1599608030000},"page":"1-5","source":"Crossref","is-referenced-by-count":3,"title":["Extracranial Meningioma in the Scalp with Concurrent Steatocystoma"],"prefix":"10.1155","volume":"2020","author":[{"given":"Jiankun","family":"Tong","sequence":"first","affiliation":[{"name":"Department of Pathology, New York Presbyterian Queens, 56-45 Main Street, Flushing, NY 11355, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7791-5522","authenticated-orcid":true,"given":"Sergei A.","family":"Aksenov","sequence":"additional","affiliation":[{"name":"Department of Pathology, New York Presbyterian Queens, 56-45 Main Street, Flushing, NY 11355, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mitchell I.","family":"Chorost","sequence":"additional","affiliation":[{"name":"Department of Surgery, St. Francis Hospital, 100 Port Washington Blvd., Roslyn, NY 11576, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William H.","family":"Rodgers","sequence":"additional","affiliation":[{"name":"Department of Pathology, New York Presbyterian Queens, 56-45 Main Street, Flushing, NY 11355, USA"},{"name":"Weill Cornell Medical College, 525 East 68th Street, Box 130, New York, NY 10065, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1227\/01.NEU.0000188281.91351.B9"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.4274\/meandros.2137"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1007\/s12105-009-0118-1"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1111\/j.1346-8138.1995.tb03884.x"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198706000-00008"},{"issue":"9","key":"7","first-page":"1883","volume":"33","year":"2006","journal-title":"The Journal of Rheumatology"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.5858\/arpa.2010-0505-RS"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2407-12-275"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.3342\/ceo.2013.6.4.266"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1016\/j.surneu.2006.02.043"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1080\/00016480310014903"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1080\/02841850510021210"},{"key":"14","first-page":"29","volume":"25","year":"2017","journal-title":"Hong Kong Journal of Dermatology & Venereology"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1016\/j.ad.2013.08.007"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1159\/000488584"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.5021\/ad.2009.21.1.106"},{"key":"18","first-page":"255","volume-title":"Cysts","year":"2005"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1097\/00000372-199702000-00017"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1093\/neuonc\/not110"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2990.1992.tb00825.x"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1227\/00006123-198606000-00015"}],"container-title":["Case Reports in Pathology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cripa\/2020\/6539064.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cripa\/2020\/6539064.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cripa\/2020\/6539064.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,9,8]],"date-time":"2020-09-08T23:33:52Z","timestamp":1599608032000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/cripa\/2020\/6539064\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,9,8]]},"references-count":21,"alternative-id":["6539064","6539064"],"URL":"https:\/\/doi.org\/10.1155\/2020\/6539064","relation":{},"ISSN":["2090-6781","2090-679X"],"issn-type":[{"value":"2090-6781","type":"print"},{"value":"2090-679X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,9,8]]}}}
