Metastatic disease generally presents with identification of known primary lesion; however, in 3.2% of patients, metastatic disease is discovered with unknown primary lesion\/site. Rarely, melanoma is diagnosed as a primary lesion in visceral organs. Suspected primary hepatic melanoma is exceedingly rare and described in only a few case reports. We present the case of a 69-year-old Caucasian male who was found to have a hepatic melanoma on final pathology after resection of suspected primary hepatic malignancy. After a thorough postoperative workup, a primary lesion was unable to be identified. As such, a visceral primary lesion is considered.<\/jats:p>","DOI":"10.1177\/0003134820940732","type":"journal-article","created":{"date-parts":[[2020,10,19]],"date-time":"2020-10-19T22:14:57Z","timestamp":1603145697000},"page":"511-513","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Primary Heptaic Melanoma or Melanoma of Unknown Primary?"],"prefix":"10.1177","volume":"87","author":[{"given":"Jesse P.","family":"Wright","sequence":"first","affiliation":[{"name":"Department of Colorectal Surgery, AdventHealth - Orlando, Orlando, FL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sunil K.","family":"Geevarghese","sequence":"additional","affiliation":[{"name":"Department of Surgery, Vanderbilt University Medical Center, Nashville, TN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,10,19]]},"reference":[{"key":"bibr1-0003134820940732","doi-asserted-by":"publisher","DOI":"10.15586\/codon.noncutaneousmelanoma.2018.ch7"},{"key":"bibr2-0003134820940732","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2005.03.006"},{"key":"bibr3-0003134820940732","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v13.i29.4027"},{"key":"bibr4-0003134820940732","doi-asserted-by":"publisher","DOI":"10.1186\/1477-7819-12-362"}],"container-title":["The American Surgeon\u2122"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0003134820940732","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/0003134820940732","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0003134820940732","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T12:33:40Z","timestamp":1777379620000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/0003134820940732"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,10,19]]},"references-count":4,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2021,4]]}},"alternative-id":["10.1177\/0003134820940732"],"URL":"https:\/\/doi.org\/10.1177\/0003134820940732","relation":{},"ISSN":["0003-1348","1555-9823"],"issn-type":[{"value":"0003-1348","type":"print"},{"value":"1555-9823","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,10,19]]}}}
