There are, however, occasions where lesions are found in distant sites such as lymph nodes, viscera and subcutaneous tissues without clinically apparent skin involvement. This is known as metastatic melanoma of unknown primary (MUP). Its presentation in skeletal muscle is rare, and the available literature is sparse. This article presents an 85-year-old woman with a MUP presenting in the right temporalis muscle, which was diagnosed with the aid of the ultrasound-guided core biopsy. The melanoma deposit was successfully excised, and no recurrence was identified. The patient is now under close follow-up.<\/jats:p>","DOI":"10.1136\/bcr-2017-221577","type":"journal-article","created":{"date-parts":[[2017,10,20]],"date-time":"2017-10-20T10:40:11Z","timestamp":1508496011000},"page":"bcr-2017-221577","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Metastatic melanoma of unknown primary in the temporalis muscle"],"prefix":"10.1136","volume":"2017","author":[{"given":"Marco","family":"Dalle Carbonare","sequence":"first","affiliation":[{"name":"Oral and Maxillofacial Surgery Department, Eastbourne District General Hospital, Eastbourne, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mei Xien","family":"Goh","sequence":"additional","affiliation":[{"name":"Oral and Maxillofacial Surgery Department, Eastbourne District General Hospital, Eastbourne, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zainab","family":"AlshiekhAli","sequence":"additional","affiliation":[{"name":"Pathology Department, Eastbourne District General Hospital, Eastbourne, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Howlett","sequence":"additional","affiliation":[{"name":"Radiology Department, Eastbourne District General Hospital, Eastbourne, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2017,10,20]]},"reference":[{"key":"2025082707050127000_2017.oct20_1.bcr-2017-221577.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.critrevonc.2010.04.007"},{"key":"2025082707050127000_2017.oct20_1.bcr-2017-221577.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2014.09.029"},{"key":"2025082707050127000_2017.oct20_1.bcr-2017-221577.3","doi-asserted-by":"crossref","first-page":"704","DOI":"10.1159\/000453592","article-title":"Unknown Primary Melanoma: Worldwide Survey on Clinical Management","volume":"232","author":"Ribero","year":"2016","journal-title":"Dermatology"},{"key":"2025082707050127000_2017.oct20_1.bcr-2017-221577.4","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0142(19970501)79:9<1816::AID-CNCR26>3.0.CO;2-#"},{"key":"2025082707050127000_2017.oct20_1.bcr-2017-221577.5","first-page":"341","article-title":"Malignant melanoma of unknown primary origin","volume":"117","author":"Das Gupta","year":"1963","journal-title":"Surg Gynecol Obstet"},{"key":"2025082707050127000_2017.oct20_1.bcr-2017-221577.6","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.12.9363"},{"key":"2025082707050127000_2017.oct20_1.bcr-2017-221577.7","doi-asserted-by":"publisher","DOI":"10.6004\/jnccn.2011.0117"},{"key":"2025082707050127000_2017.oct20_1.bcr-2017-221577.8","doi-asserted-by":"publisher","DOI":"10.1136\/jcp.2005.033613"},{"key":"2025082707050127000_2017.oct20_1.bcr-2017-221577.9","doi-asserted-by":"publisher","DOI":"10.1016\/0007-1226(90)90092-E"},{"key":"2025082707050127000_2017.oct20_1.bcr-2017-221577.10","first-page":"605","article-title":"Improved detection of metastatic melanoma by T2*-weighted imaging","volume":"27","author":"Gaviani","year":"2006","journal-title":"AJNR Am J Neuroradiol"},{"key":"2025082707050127000_2017.oct20_1.bcr-2017-221577.11","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.165.6.7484597"},{"key":"2025082707050127000_2017.oct20_1.bcr-2017-221577.12","doi-asserted-by":"publisher","DOI":"10.1309\/AJCP2SD8RFQEUZJW"},{"key":"2025082707050127000_2017.oct20_1.bcr-2017-221577.13","doi-asserted-by":"publisher","DOI":"10.1309\/AJCPOIE0CZNAT6SQ"},{"key":"2025082707050127000_2017.oct20_1.bcr-2017-221577.14","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1155\/2012\/647684","article-title":"Metastatic behavior in melanoma: timing, pattern, survival, and influencing factors","volume":"2012","author":"Tas","year":"2012","journal-title":"J Oncol"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2017-221577","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T14:05:07Z","timestamp":1756303507000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2017-221577"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,10,20]]},"references-count":14,"alternative-id":["10.1136\/bcr-2017-221577"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2017-221577","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,10,20]]}}}
