Rendering a definitive diagnosis may pose a challenge particularly in a resource-limited setting. We report a case of primary osteosarcoma of the urinary bladder presenting with hematuria, dysuria and positive history of schistosomal contact. Computed tomography intravenous urogram revealed a large heterogeneous mass at the right superolateral aspect of the urinary bladder. Morphological evaluation of the biopsy and a minimal panel of immunohistochemical antibodies of vimentin and cytokeratin 20 ruled out potential differentials and thus confirmed the diagnosis of osteosarcoma.<\/jats:p>","DOI":"10.1093\/jscr\/rjaa236","type":"journal-article","created":{"date-parts":[[2020,6,16]],"date-time":"2020-06-16T19:10:07Z","timestamp":1592334607000},"source":"Crossref","is-referenced-by-count":3,"title":["Diagnosis of primary osteosarcoma of the urinary bladder in a resource-limited setting: a case report and review of the literature"],"prefix":"10.1093","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7226-0168","authenticated-orcid":false,"given":"Alex","family":"Mremi","sequence":"first","affiliation":[{"name":"Department of Pathology, Kilimanjaro Christian Medical Centre (KCMC), Moshi, Tanzania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeremia J","family":"Pyuza","sequence":"additional","affiliation":[{"name":"Department of Pathology, Kilimanjaro Christian Medical Centre (KCMC), Moshi, Tanzania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicholas","family":"Bartholomeo","sequence":"additional","affiliation":[{"name":"Department of Urology, Kilimanjaro Christian Medical Centre (KCMC), Moshi, Tanzania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alice A","family":"Andongolile","sequence":"additional","affiliation":[{"name":"Kilimanjaro Clinical Research Institute (KCRI), Kilimanjaro Christian Medical Centre (KCMC), Moshi, Tanzania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James J","family":"Yahaya","sequence":"additional","affiliation":[{"name":"Department of Biomedical Science, College of Health Sciences (CHS), The University of Dodoma, Dodoma, Tanzania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2020,7,23]]},"reference":[{"key":"2020072322264298300_ref1","doi-asserted-by":"crossref","first-page":"350","DOI":"10.1002\/1097-0142(19860115)57:2<350::AID-CNCR2820570227>3.0.CO;2-S","article-title":"Primary osteogenic sarcoma of the bladder.
