It generally occurs in the female genital tract, especially in the uterus, gastrointestinal tract, retroperitoneum and rarely in the head and neck. Here we report a case of leiomyosarcoma in a 24-year-old man with a 6-month history of toothache and extraction of three right upper molar teeth, that was complicated by fistula tract formation and facial swelling. Imaging studies demonstrated tumoural lesions involving the right maxillary sinus, nasal cavity, hard palate and orbit. The histopathological and immunohistochemical studies confirmed that it was leiomyosarcoma.<\/jats:p>","DOI":"10.1136\/bcr-2013-200933","type":"journal-article","created":{"date-parts":[[2013,12,5]],"date-time":"2013-12-05T06:49:35Z","timestamp":1386226175000},"page":"bcr2013200933","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Leiomyosarcoma of the maxilla in a 24-year-old man who initially presented with odontalgia, and suffered from tumour mismanagement"],"prefix":"10.1136","volume":"2013","author":[{"given":"Shokouh","family":"Taghipour Zahir","sequence":"first","affiliation":[{"name":"Department of Pathology, Shahid Sadoughi University of Medical Sciences, Yazd, Islamic Republic of Iran"},{"name":"Department of Pathology, Mortaz General Hospital, Yazd, Islamic Republic of Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naser Sefidrokh","family":"Sharahjin","sequence":"additional","affiliation":[{"name":"Department of Radiology, Shahid Sadoughi University of Medical Sciences, Yazd, Islamic Republic of Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2013,12,5]]},"reference":[{"key":"2025082723400973000_2013.dec05_1.bcr2013200933.1","first-page":"174","article-title":"Leiomyosarcoma of the maxillary sinus","volume":"64","author":"Chew","year":"2009","journal-title":"Med J Malaysia"},{"key":"2025082723400973000_2013.dec05_1.bcr2013200933.2","doi-asserted-by":"crossref","first-page":"122","DOI":"10.1177\/014556130408300213","article-title":"Leiomyosarcoma of the maxillary sinuses: report of two cases","volume":"83","author":"Prasad","year":"2004","journal-title":"Ear Nose Throat J"},{"key":"2025082723400973000_2013.dec05_1.bcr2013200933.3","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2559.2002.01412.x"},{"key":"2025082723400973000_2013.dec05_1.bcr2013200933.4","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-051x.2002.290214.x"},{"key":"2025082723400973000_2013.dec05_1.bcr2013200933.5","first-page":"115","article-title":"Leiomyosarcoma of the ethmoidal cells","volume":"39","author":"Keck","year":"2001","journal-title":"Rhinology"},{"key":"2025082723400973000_2013.dec05_1.bcr2013200933.6","doi-asserted-by":"publisher","DOI":"10.1053\/joms.2001.22691"},{"key":"2025082723400973000_2013.dec05_1.bcr2013200933.7","doi-asserted-by":"crossref","first-page":"221","DOI":"10.1259\/bjr.71.842.9579188","article-title":"Leiomyosarcoma of the maxillary sinus: CT and MRI findings","volume":"71","author":"Tanaka","year":"1998","journal-title":"Br J Radiol"},{"key":"2025082723400973000_2013.dec05_1.bcr2013200933.8","doi-asserted-by":"publisher","DOI":"10.1007\/BF00464348"},{"key":"2025082723400973000_2013.dec05_1.bcr2013200933.9","first-page":"17","article-title":"Leiomyosarcoma of the nasal cavity and paranasal sinuses","volume":"29","author":"Richter","year":"1981","journal-title":"HNO"},{"key":"2025082723400973000_2013.dec05_1.bcr2013200933.10","doi-asserted-by":"publisher","DOI":"10.1016\/0030-4220(80)90333-3"},{"key":"2025082723400973000_2013.dec05_1.bcr2013200933.11","doi-asserted-by":"crossref","first-page":"52","DOI":"10.1007\/s00784-003-0233-4","article-title":"Sarcomas of the oral and maxillofacial region: a review of 32 cases in 25years","volume":"8","author":"Yamaguchi","year":"2004","journal-title":"Clin Oral Investig"},{"key":"2025082723400973000_2013.dec05_1.bcr2013200933.12","doi-asserted-by":"publisher","DOI":"10.1001\/archoto.2011.147"},{"key":"2025082723400973000_2013.dec05_1.bcr2013200933.13","first-page":"10","article-title":"Leiomyosarcoma of the maxillary sinus: an unusual site of occurrence","volume":"2","author":"Shruti","year":"2008","journal-title":"Internet J Head Neck Surg"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2013-200933","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T06:40:21Z","timestamp":1756363221000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2013-200933"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,12,5]]},"references-count":13,"alternative-id":["10.1136\/bcr-2013-200933"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2013-200933","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,12,5]]}}}
