He presented following a pathological fracture with a falsely reassuring core and fine-needle aspiration biopsy. The initial biopsy was suggestive of an aneurysmal bone cyst and was therefore treated conservatively without further follow-up. The rapid increase in size over the next 8\u2005months triggered a repeat presentation and subsequent repeat biopsy. The open biopsy confirmed high-grade osteosarcoma and the patient underwent claviculectomy with neoadjuvant chemotherapy.<\/jats:p>","DOI":"10.1136\/bcr-2014-208859","type":"journal-article","created":{"date-parts":[[2015,4,24]],"date-time":"2015-04-24T06:00:33Z","timestamp":1429855233000},"page":"bcr2014208859","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Primary osteosarcoma of the clavicle and the perils of bone biopsy"],"prefix":"10.1136","volume":"2015","author":[{"given":"William J","family":"Cundy","sequence":"first","affiliation":[{"name":"Department of Orthopaedics and Trauma, Royal Adelaide Hospital, Adelaide, South Australia, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher","family":"Carter","sequence":"additional","affiliation":[{"name":"Department of Cytopathology, SA Pathology, Adelaide, South Australia, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deepak","family":"Dhatrak","sequence":"additional","affiliation":[{"name":"Department of Cytopathology, SA Pathology, Adelaide, South Australia, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark","family":"Clayer","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Trauma, Royal Adelaide Hospital, Adelaide, South Australia, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2015,4,24]]},"reference":[{"key":"2025082704035321000_2015.apr23_1.bcr2014208859.1","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-007-0397-7"},{"key":"2025082704035321000_2015.apr23_1.bcr2014208859.2","doi-asserted-by":"publisher","DOI":"10.1634\/theoncologist.9-4-422"},{"key":"2025082704035321000_2015.apr23_1.bcr2014208859.3","doi-asserted-by":"publisher","DOI":"10.1007\/s00402-010-1237-6"},{"key":"2025082704035321000_2015.apr23_1.bcr2014208859.4","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-006-0212-x"},{"key":"2025082704035321000_2015.apr23_1.bcr2014208859.5","doi-asserted-by":"crossref","first-page":"397","DOI":"10.3928\/01477447-20100429-16","article-title":"Bone tumors of the clavicle: risk of malignancy in the elderly and safe needle biopsy","volume":"33","author":"Basarir","year":"2010","journal-title":"Orthopedics"},{"key":"2025082704035321000_2015.apr23_1.bcr2014208859.6","doi-asserted-by":"crossref","unstructured":"Khalbuss WE , Parwani AV .
