Here, we describe a case of pan in the setting of a known breast ductal carcinoma in situ, which, to our knowledge, had not been described in association with pan. As a result, thorough investigation was undertaken to search for another concurrent neoplasm that would better explain the development of pan. In so doing, we identified a coexisting metastatic cholangiocarcinoma. We thus conclude that when pan is observed in an uncommon association with a known malignancy, further investigation should be undertaken to explore whether a more likely occult culprit exists.<\/jats:p>","DOI":"10.3747\/co.19.997","type":"journal-article","created":{"date-parts":[[2012,8,8]],"date-time":"2012-08-08T20:10:19Z","timestamp":1344456619000},"page":"299-302","source":"Crossref","is-referenced-by-count":7,"title":["Occult Cause of Paraneoplastic Acanthosis Nigricans in a Patient with Known Breast Dcis: Case and Review"],"prefix":"10.3390","volume":"19","author":[{"given":"B.D.","family":"Jakubovic","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.F.","family":"Sawires","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.N.","family":"Adam","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2012,8,1]]},"container-title":["Current Oncology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.mdpi.com\/1718-7729\/19\/4\/997\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,2,18]],"date-time":"2021-02-18T17:54:22Z","timestamp":1613670862000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.mdpi.com\/1718-7729\/19\/4\/997"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,8,1]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2012,8]]}},"alternative-id":["co.19.997"],"URL":"https:\/\/doi.org\/10.3747\/co.19.997","relation":{},"ISSN":["1718-7729"],"issn-type":[{"value":"1718-7729","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,8,1]]}}}
