With most clinical manifestations occurring due to mass effect, Pancoast syndrome is a known complication that includes shoulder and arm musculoskeletal pain, Horner\u2019s syndrome and neurological complications of the upper extremities, including weakness and atrophy. Even though adenocarcinoma is the most common cause of Pancoast syndrome among lung cancers, other malignancies can be responsible as well. Treatment is similar to that of other standard NSCLC treatments that include chemotherapy, radiation, immunotherapy and surgery. Here we report a patient with Pancoast syndrome secondary to a poorly differentiated malignant neoplasm composed of anaplastic cells.<\/jats:p>","DOI":"10.36518\/2689-0216.1076","type":"journal-article","created":{"date-parts":[[2021,2,27]],"date-time":"2021-02-27T03:13:26Z","timestamp":1614395606000},"source":"Crossref","is-referenced-by-count":1,"title":["Pancoast Syndrome Due to High Grade Anaplastic Tumor"],"prefix":"10.36518","volume":"2","author":[{"given":"Christian","family":"Almanzar","sequence":"first","affiliation":[{"name":"Brandon Regional Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seth","family":"Maxwell","sequence":"additional","affiliation":[{"name":"Brandon Regional Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mauricio","family":"Gomez","sequence":"additional","affiliation":[{"name":"Brandon Regional Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Omar","family":"Ansari","sequence":"additional","affiliation":[{"name":"Brandon regional Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis","family":"Silva","sequence":"additional","affiliation":[{"name":"Brandon Regional Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"22435","published-online":{"date-parts":[[2021,2,26]]},"container-title":["HCA Healthcare Journal of Medicine"],"original-title":[],"language":"en","deposited":{"date-parts":[[2026,11,6]],"date-time":"2026-11-06T09:33:30Z","timestamp":1793957610000},"score":1,"resource":{"primary":{"URL":"https:\/\/scholarlycommons.hcahealthcare.com\/hcahealthcarejournal\/vol2\/iss1\/8"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,2,26]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2021,2,26]]}},"URL":"https:\/\/doi.org\/10.36518\/2689-0216.1076","relation":{},"ISSN":["2689-0216"],"issn-type":[{"value":"2689-0216","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,2,26]]}}}
