This tumour was secreting ectopic adrenocorticotropic hormone (ACTH), a paraneoplastic endocrine phenomenon, which resulted in Cushing syndrome symptomatology. Though most ectopic ACTH-producing lung cancers are either small cell or carcinoid tumours, this was in fact a large cell neuroendocrine cancer (LCNEC). Patient underwent surgical resection and adjuvant\/neoadjuvant chemotherapy with radiation; however, he succumbed to LCNEC given aggressive nature of the disease.<\/jats:p>","DOI":"10.1136\/bcr-2016-219156","type":"journal-article","created":{"date-parts":[[2017,3,25]],"date-time":"2017-03-25T05:37:14Z","timestamp":1490420234000},"page":"bcr2016219156","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Ectopic ACTH-producing large cell neuroendocrine Pancoast tumour presenting as Horner syndrome"],"prefix":"10.1136","volume":"2017","author":[{"given":"Rajanshu","family":"Verma","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandra","family":"Lambert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Harold H","family":"Katz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott J","family":"Benson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2017,3,24]]},"reference":[{"key":"2025042705433334000_2017.mar23_1.bcr2016219156.1","unstructured":"Husain AN .
