We report a case of primary leiomyosarcoma of the peritoneal cavity which clinically presented with suprapubic, freely mobile, nontender mass which measured 10\u00d710 cm in size. Contrast enhanced computed tomography revealed well defined heterogenous hypodense solid cystic mass. The mass was surgically excised out in its entirety. The histopathological examination revealed spindle cells arranged in alternating fascicles having pleomorphic nuclei, indistinct margin and eosinophilic cytoplasm with foci of haemorrhage, necrosis and 5-6 mitosis\/HPF. The spindle cells were immunoreactive for smooth muscle actin, desmin and negative for S-100, CD-34 and c-kit. Histopathology and immunohistochemistry were helpful in making the final confirmatory diagnosis. Leiomyosarcomas are aggressive tumors, with poor prognosis and often difficult to treat. The survival rates are lowest among all soft tissue sarcomas.<\/jats:p>","DOI":"10.4081\/rt.2014.5165","type":"journal-article","created":{"date-parts":[[2014,11,7]],"date-time":"2014-11-07T05:04:53Z","timestamp":1415336693000},"page":"22-23","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Primary Leiomyosarcoma of Peritoneal Cavity"],"prefix":"10.1177","volume":"6","author":[{"given":"Jyotsna Naresh","family":"Bharti","sequence":"first","affiliation":[{"name":"Department of Pathology, Maulana Azad Medical College, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Biswajit","family":"Dey","sequence":"additional","affiliation":[{"name":"Department of Pathology, Maulana Azad Medical College, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Parth","family":"Desai","sequence":"additional","affiliation":[{"name":"Department of Pathology, Maulana Azad Medical College, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richa","family":"Gupta","sequence":"additional","affiliation":[{"name":"Department of Pathology, Maulana Azad Medical College, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nita","family":"Khurana","sequence":"additional","affiliation":[{"name":"Department of Pathology, Maulana Azad Medical College, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gauri","family":"Gandhi","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Maulana Azad Medical College, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2014,3,1]]},"reference":[{"key":"bibr1-rt.2014.5165","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-443-06688-7.00006-7"},{"key":"bibr2-rt.2014.5165","first-page":"197","volume-title":"Pathology and genetics of tumours of the breast and female genital organs","author":"Mok SC","year":"2003"},{"key":"bibr3-rt.2014.5165","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.139.2.291"},{"key":"bibr4-rt.2014.5165","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.152.1.6729102"},{"key":"bibr5-rt.2014.5165","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.167.2.8686629"},{"key":"bibr6-rt.2014.5165","doi-asserted-by":"publisher","DOI":"10.1097\/00004728-199607000-00026"},{"key":"bibr7-rt.2014.5165","first-page":"301","volume-title":"Clinical pathology of soft-tissue tumors","author":"Hansen CH","year":"2001"},{"key":"bibr8-rt.2014.5165","first-page":"491","volume-title":"Soft tissue tumors","author":"Enzinger FM","year":"1995"},{"key":"bibr9-rt.2014.5165","unstructured":"FlemingIDCooperJSHensonDE AJCC Cancer staging manual, ed 5.
