An 81-year-old woman with SDC underwent a total parotidectomy with facial nerve sacrifice and a neck dissection. Following surgery, she was diagnosed with disseminated bone marrow metastases. She underwent chemotherapy and trastuzumab for palliation. We present a case of SDC of the parotid which was diagnosed with disseminated bone marrow metastasis following surgery for the primary. This case also highlights the importance of having a high index of suspicion while evaluating highly aggressive tumours like SDC for any atypical findings during workup.<\/jats:p>","DOI":"10.1136\/bcr-2018-226636","type":"journal-article","created":{"date-parts":[[2018,12,18]],"date-time":"2018-12-18T17:19:47Z","timestamp":1545153587000},"page":"bcr-2018-226636","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Bone marrow metastases in salivary duct carcinoma of the parotid gland"],"prefix":"10.1136","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9028-8746","authenticated-orcid":false,"given":"Ameya","family":"Asarkar","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\/HNS, Louisiana State University Health Sciences Center Shreveport, Shreveport, Louisiana, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amol","family":"Takalkar","sequence":"additional","affiliation":[{"name":"Center for Molecular Imaging and Therapy, Biomedical Research Foundation of Northwest Louisiana, Shreveport, Louisiana, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manish","family":"Dhawan","sequence":"additional","affiliation":[{"name":"Oncology Associates of Northwest Louisiana, Highland Clinic, Shreveport, Louisiana, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cherie Ann O","family":"Nathan","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\/HNS, Louisiana State University Health Sciences Center Shreveport, Shreveport, Louisiana, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2018,12,3]]},"reference":[{"key":"2025082708202557000_11.1.bcr-2018-226636.1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00301495"},{"key":"2025082708202557000_11.1.bcr-2018-226636.2","doi-asserted-by":"crossref","first-page":"1763","DOI":"10.5858\/133.11.1763","article-title":"Update on selected salivary gland neoplasms","volume":"133","author":"McHugh","year":"2009","journal-title":"Arch Pathol Lab Med"},{"key":"2025082708202557000_11.1.bcr-2018-226636.3","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.21116"},{"key":"2025082708202557000_11.1.bcr-2018-226636.4","doi-asserted-by":"publisher","DOI":"10.1016\/S0046-8177(96)90162-8"},{"key":"2025082708202557000_11.1.bcr-2018-226636.5","doi-asserted-by":"publisher","DOI":"10.1159\/000332564"},{"key":"2025082708202557000_11.1.bcr-2018-226636.6","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2559.1995.tb01440.x"},{"key":"2025082708202557000_11.1.bcr-2018-226636.7","unstructured":"Amin MB , Edge SB , Greene FL , et al . eds.
