We report a case of a young adult presenting with retention of urine and was found to have a large abdomino-pelvic mass causing bony destruction and compression of pelvic viscera. A biopsy revealed a cellular tumor composed of spindle to oval cells arranged in a hemangiopericytomatous pattern. Histopathology was suggestive of poorly differentiated synovial sarcoma. Immunohistochemistry (IHC) was positive for vimentin, CD 99, Bcl2, Mic2 and focally for EMA and negative for CD 34, CK, desmin, synaptophysin, and WT1. Due to equivocal IHC findings molecular analysis was done which confirmed the diagnosis as synovial sarcoma.<\/jats:p>","DOI":"10.4103\/0377-4929.125336","type":"journal-article","created":{"date-parts":[[2014,1,18]],"date-time":"2014-01-18T01:32:10Z","timestamp":1390008730000},"page":"396-398","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":3,"title":["Dumb-bell shaped poorly differentiated pelvic synovial sarcoma with molecular confirmation: A rare presentation of an uncommon disease entity"],"prefix":"10.4103","volume":"56","author":[{"given":"Roumina","family":"Hasan","sequence":"first","affiliation":[{"name":"Department of Pathology, Kasturba Medical College, Manipal University, Manipal, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandeep","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Radiodiagnosis, Kasturba Medical College, Manipal University, Manipal, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lakshmi","family":"Rao","sequence":"additional","affiliation":[{"name":"Department of Pathology, Kasturba Medical College, Manipal University, Manipal, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-20250920","doi-asserted-by":"crossref","first-page":"1543","DOI":"10.1148\/rg.265065084","article-title":"Imaging of Synovial Sarcoma with Radiologic-Pathologic Correlation1","volume":"26","author":"Murphey","year":"2006","journal-title":"Radiographics"},{"key":"R3-20250920","first-page":"48A","article-title":"Primary intra-abdominal synovial sarcoma","volume":"36","author":"Narula","year":"2007","journal-title":"Appl Radiol"},{"key":"R4-20250920","first-page":"5859","article-title":"Genome-Wide Analysis of Gene Expression in Synovial Sarcomas Using a cDNA Microarray","volume":"62","author":"Nagayama","year":"2002","journal-title":"Cancer Res"},{"key":"R5-20250920","doi-asserted-by":"crossref","first-page":"67","DOI":"10.4103\/0019-509X.41774","article-title":"A t(X; 18) SYT-SSX2 positive synovial sarcoma in the pelvis of a young adult male: A rare case report with review of literature","volume":"45","author":"Rekhi","year":"2008","journal-title":"Indian J Cancer"},{"key":"R6-20250920","doi-asserted-by":"crossref","first-page":"97","DOI":"10.1002\/(SICI)1096-911X(199902)32:2<97::AID-MPO5>3.0.CO;2-J","article-title":"Synovial sarcoma mimicking desmoplastic small round-cell tumor: Critical role for molecular diagnosis","volume":"32","author":"Cole","year":"1999","journal-title":"Med Pediatr Oncol"},{"key":"R7-20250920","doi-asserted-by":"crossref","first-page":"102","DOI":"10.1186\/1477-7819-8-102","article-title":"Malignant inguinal monophasic synovial sarcoma: Report of a case and review of literature","volume":"8","author":"Xu","year":"2010","journal-title":"World J Surg Oncol"},{"key":"R8-20250920","doi-asserted-by":"crossref","first-page":"140","DOI":"10.1097\/00004728-200401000-00024","article-title":"Synovial sarcoma of the soft tissues: Prognostic significance of imaging features","volume":"28","author":"Tateishi","year":"2004","journal-title":"J Comput Assist Tomogr"},{"key":"R9-20250920","doi-asserted-by":"crossref","first-page":"588","DOI":"10.1046\/j.1365-2559.2003.01652.x","article-title":"Calponin and h-caldesmon expression in synovial sarcoma; the use of calponin in diagnosis","volume":"42","author":"Fisher","year":"2003","journal-title":"Histopathology"}],"container-title":["Indian Journal of Pathology and Microbiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/00004270-201356040-00012","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T13:49:58Z","timestamp":1787838598000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/00004270-201356040-00012"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,10]]},"references-count":8,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2013]]}},"URL":"https:\/\/doi.org\/10.4103\/0377-4929.125336","relation":{},"ISSN":["0377-4929","0974-5130"],"issn-type":[{"value":"0377-4929","type":"print"},{"value":"0974-5130","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,10]]}}}
