Only two cases of a primary CCS arising in the lung have been reported in the literature, and neither were located in the lung apex. We report a case of a primary CCS located in the lung apex that originally presented as ptosis, as well as arm pain and weakness. Distant metastasis was discovered on diagnosis, which led to irreversible paraplegia and death of the patient.<\/jats:p>","DOI":"10.1136\/bcr-2019-231556","type":"journal-article","created":{"date-parts":[[2020,1,10]],"date-time":"2020-01-10T04:06:44Z","timestamp":1578629204000},"page":"e231556","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Primary clear cell sarcoma in the lung apex with spinal metastasis: a fatal outcome"],"prefix":"10.1136","volume":"13","author":[{"given":"RemyGrace","family":"Sass","sequence":"first","affiliation":[{"name":"College of Medicine, University of Nebraska Medical Center, Omaha, Nebraska, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pavan Kumar","family":"Tandra","sequence":"additional","affiliation":[{"name":"Hematology-Oncology, University of Nebraska Medical Center, Omaha, Nebraska, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicole","family":"Shonka","sequence":"additional","affiliation":[{"name":"Hematology-Oncology, University of Nebraska Medical Center, Omaha, Nebraska, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Melissa","family":"Manzer","sequence":"additional","affiliation":[{"name":"Radiology, University of Nebraska Medical Center, Omaha, Nebraska, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,1,9]]},"reference":[{"key":"2025082801361856000_13.1.e231556.1","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(196509)18:9<1163::AID-CNCR2820180916>3.0.CO;2-0"},{"key":"2025082801361856000_13.1.e231556.2","doi-asserted-by":"crossref","first-page":"839","DOI":"10.1080\/14737140.2016.1197122","article-title":"Biology and management of clear cell sarcoma: state of the art and future perspectives","volume":"16","author":"Cornillie","year":"2016","journal-title":"Expert Rev Anticancer Ther"},{"key":"2025082801361856000_13.1.e231556.3","doi-asserted-by":"crossref","first-page":"1711","DOI":"10.1007\/s00432-018-2693-6","article-title":"The epidemiology and survivorship of clear cell sarcoma: a national cancer database (NCDB) review","volume":"144","author":"Gonzaga","year":"2018","journal-title":"J Cancer Res Clin Oncol"},{"key":"2025082801361856000_13.1.e231556.4","doi-asserted-by":"crossref","first-page":"111","DOI":"10.1007\/s00428-016-1943-8","article-title":"Primary pulmonary clear cell sarcoma\u2014the first two reported cases","volume":"469","author":"Goh","year":"2016","journal-title":"Virchows Arch"},{"key":"2025082801361856000_13.1.e231556.5","doi-asserted-by":"crossref","DOI":"10.1186\/1477-7819-4-48","article-title":"Clear cell sarcoma of the scapula.
