Computed tomography urography showed an ill-defined heterogeneously enhancing soft tissue lesion near the neck of the bladder. The patient was advised of radical cystectomy with an ileal conduit for which the patient was unwilling. Hence, transurethral resection of bladder tumor was performed. Histopathological evaluation of surgical specimen revealed it to be primary osteosarcoma of the urinary bladder. The patient was given radiotherapy. Regular follow-up revealed no abnormality, and the patient showed excellent response with normal urinary tract function. Primary urinary bladder sarcomas are extremely rare clinical entities. To date, in scientific literature, fewer than 50 primary bladder osteosarcomas have been reported.<\/jats:p>","DOI":"10.4103\/ijc.ijc_823_21","type":"journal-article","created":{"date-parts":[[2025,8,11]],"date-time":"2025-08-11T17:00:23Z","timestamp":1754931623000},"page":"305-307","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Bladder preserving approach for treatment of primary osteogenic sarcoma of bladder: A rare case report"],"prefix":"10.4103","volume":"62","author":[{"given":"Ravi","family":"Batra","sequence":"first","affiliation":[{"name":"Department of Surgery, Mahatma Gandhi Institute of Medical Science, Sewagram, Wardha, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2962-416X","authenticated-orcid":false,"given":"Sneha","family":"Yadav","sequence":"additional","affiliation":[{"name":"Department of Surgery, Mahatma Gandhi Institute of Medical Science, Sewagram, Wardha, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mayur","family":"Chaure","sequence":"additional","affiliation":[{"name":"Department of Surgery, Mahatma Gandhi Institute of Medical Science, Sewagram, Wardha, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shreyak","family":"Garg","sequence":"additional","affiliation":[{"name":"Department of Surgery, Mahatma Gandhi Institute of Medical Science, Sewagram, Wardha, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saurabh","family":"Uplenchwar","sequence":"additional","affiliation":[{"name":"Department of Surgery, Mahatma Gandhi Institute of Medical Science, Sewagram, Wardha, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dilip","family":"Gupta","sequence":"additional","affiliation":[{"name":"Department of Surgery, Mahatma Gandhi Institute of Medical Science, Sewagram, Wardha, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2025,8,11]]},"reference":[{"key":"R1-20250812","doi-asserted-by":"crossref","first-page":"887","DOI":"10.1097\/00000658-194311000-00010","article-title":"Primary osteogenic sarcoma of the bladder","volume":"118","author":"Crane","year":"1943","journal-title":"Ann Surg"},{"key":"R2-20250812","doi-asserted-by":"crossref","first-page":"2253","DOI":"10.1002\/1097-0142(19951201)76:11<2253::AID-CNCR2820761112>3.0.CO;2-8","article-title":"A review of 40 patients with extraskeletal osteosarcoma","volume":"76","author":"Lee","year":"1995","journal-title":"Cancer"},{"key":"R3-20250812","doi-asserted-by":"crossref","first-page":"39","DOI":"10.1186\/1752-1947-3-39","article-title":"Primary osteosarcoma of the urinary bladder following cyclophosphamide therapy for systemic lupus erythematosus:A case report","volume":"3","author":"Baydar","year":"2009","journal-title":"J Med Case Rep"},{"key":"R4-20250812","doi-asserted-by":"crossref","first-page":"E69","DOI":"10.5489\/cuaj.10161","article-title":"Carcinosarcoma of the bladder:Case report and review of the literature","volume":"5","author":"Akoluk","year":"2011","journal-title":"Can Urol Assoc J"},{"key":"R5-20250812","doi-asserted-by":"crossref","first-page":"771","DOI":"10.1016\/S0090-4295(94)80228-9","article-title":"Primary osteogenic sarcoma of the urinary bladder successfully treated with combination therapy","volume":"44","author":"Phan","year":"1994","journal-title":"Urology"},{"key":"R6-20250812","doi-asserted-by":"crossref","first-page":"437","DOI":"10.1007\/BF02551110","article-title":"Primary osteosarcoma of the urinary bladder","volume":"29","author":"Okada","year":"1997","journal-title":"Int Urol Nephrol"},{"key":"R7-20250812","doi-asserted-by":"crossref","first-page":"rjaa236","DOI":"10.1093\/jscr\/rjaa236","article-title":"Diagnosis of primary osteosarcoma of the urinary bladder in a resource-limited setting:A case report and review of the literature","volume":"2020","author":"Mremi","year":"2020","journal-title":"J Surg Case Rep."},{"key":"R8-20250812","doi-asserted-by":"crossref","first-page":"1121","DOI":"10.1002\/1097-0142(197105)27:5<1121::AID-CNCR2820270519>3.0.CO;2-3","article-title":"Osteogenic sarcoma of the somatic soft tissues.
