GBC has inferior outcomes due to its advanced presentation and poor response to chemotherapy. The approximate 5-year survival rate for metastatic GBC is less than 5%, with a median survival of around 6\u2009months. Distant metastases from GBC to the bones happen in the later part of the natural history of the disease. Presentation with bony metastasis is infrequent, and less than 25 cases have been reported. Our case was an elderly man in his 70s who presented with back pain and, on workup, was detected to have adenocarcinoma of the gall bladder with disseminated lytic bony metastasis without any visceral metastasis. This case describes the natural history of such cases and discusses the role of bone scan or fluorodeoxyglucose positron emission tomography in the workup for GBC.<\/jats:p>","DOI":"10.1136\/bcr-2023-257753","type":"journal-article","created":{"date-parts":[[2024,1,10]],"date-time":"2024-01-10T00:29:25Z","timestamp":1704846565000},"page":"e257753","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Gallbladder carcinoma presenting with disseminated bony metastasis"],"prefix":"10.1136","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3779-7645","authenticated-orcid":false,"given":"Amitabh Kumar","family":"Upadhyay","sequence":"first","affiliation":[{"name":"Medical Oncology, Tata Main Hospital, Jamshedpur, Jharkhand, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shashank","family":"Shekhar","sequence":"additional","affiliation":[{"name":"Medical Oncology, Meherbai Tata Memorial Hospital, Jamshedpur, Jharkhand, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abhishek","family":"Kumar","sequence":"additional","affiliation":[{"name":"Nuclear Medicine, Tata Main Hospital, Jamshedpur, Jharkhand, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Somshankar","family":"Chowdhury","sequence":"additional","affiliation":[{"name":"Pathology, Meherbai Tata Memorial Hospital, Jamshedpur, Jharkhand, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,1,4]]},"reference":[{"key":"2025082803501108000_17.1.e257753.1","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21660"},{"key":"2025082803501108000_17.1.e257753.2","doi-asserted-by":"crossref","first-page":"33","DOI":"10.21037\/cco.2019.08.03","article-title":"Epidemiology of gallbladder cancer in India","volume":"8","author":"Dutta","year":"2019","journal-title":"Chin Clin Oncol"},{"key":"2025082803501108000_17.1.e257753.3","doi-asserted-by":"crossref","first-page":"3978","DOI":"10.3748\/wjg.v23.i22.3978","article-title":"Gallbladder cancer epidemiology, pathogenesis and molecular genetics: recent update","volume":"23","author":"Sharma","year":"2017","journal-title":"World J Gastroenterol"},{"key":"2025082803501108000_17.1.e257753.4","doi-asserted-by":"crossref","unstructured":"Prasad N , Sen S .
