We report a rare case of SMTUMP in a 44-year-old woman, who presented with vague symptoms of pharyngitis. Nasal endoscopy revealed a smooth mass in left nasal cavity. Contrast-enhanced CT and MRI scans showed features likely to be inverted papilloma or olfactory neuroblastoma or meningioma. Excision was planned and intraoperatively, frozen section revealed a probable spindle cell lesion. Final histopathological report following immunohistochemistry (IHC) &amp; immunofluoresence (IF) confirmed it to be a SMTUMP. This patient underwent complete resection via endoscopic KTP laser assisted, anterior skull base surgery with no recurrence on follow-up.<\/jats:p>","DOI":"10.1136\/bcr-2016-217386","type":"journal-article","created":{"date-parts":[[2016,11,22]],"date-time":"2016-11-22T11:18:06Z","timestamp":1479813486000},"page":"bcr2016217386","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Smooth muscle tumour of uncertain malignant potential (SMTUMP) in the nasal cavity: an incidental finding"],"prefix":"10.1136","volume":"2016","author":[{"given":"Dipak Ranjan","family":"Nayak","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery, Kasturba Medical College, Manipal, Karnataka, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Asheesh Dora","family":"Ghanpur","sequence":"additional","affiliation":[{"name":"Department of ENT, Head and Neck Surgery, Kasturba Medical College, Manipal, Karnataka, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Apoorva N","family":"Reddy","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery, Kasturba Medical College, Manipal, Karnataka, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Swati","family":"Sharma","sequence":"additional","affiliation":[{"name":"Department of Pathology, Kasturba Medical College, Manipal, Karnataka, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2016,11,22]]},"reference":[{"key":"2025082702050591000_2016.nov22_1.bcr2016217386.1","first-page":"55","article-title":"Leiomyoma of the inferior turbinates","volume":"29","author":"Huang","year":"2000","journal-title":"J Otolaryngol"},{"key":"2025082702050591000_2016.nov22_1.bcr2016217386.2","doi-asserted-by":"crossref","first-page":"297","DOI":"10.5858\/2003-127-0297-SSMCT","article-title":"Sinonasal smooth muscle cell tumors: a clinicopathologic and immunohistochemical analysis of 12 cases with emphasis on the low-grade end of the spectrum","volume":"127","author":"Huang","year":"2003","journal-title":"Arch Pathol Lab Med"},{"key":"2025082702050591000_2016.nov22_1.bcr2016217386.3","first-page":"129","article-title":"Leiomyosarcoma of the sinonasal tract: a clinicopathological study of nine cases","volume":"27","author":"Kuruvilla","year":"1990","journal-title":"Arch Otolaryngol Head Neck Surg"},{"key":"2025082702050591000_2016.nov22_1.bcr2016217386.4","doi-asserted-by":"publisher","DOI":"10.1016\/S0196-0709(96)90022-8"},{"key":"2025082702050591000_2016.nov22_1.bcr2016217386.5","doi-asserted-by":"publisher","DOI":"10.1177\/019459989411100520"},{"key":"2025082702050591000_2016.nov22_1.bcr2016217386.6","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(197505)35:5<1300::AID-CNCR2820350508>3.0.CO;2-Z"},{"key":"2025082702050591000_2016.nov22_1.bcr2016217386.7","doi-asserted-by":"publisher","DOI":"10.1016\/S0196-0709(98)90066-7"},{"key":"2025082702050591000_2016.nov22_1.bcr2016217386.8","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0347(199701)19:1<63::AID-HED12>3.0.CO;2-S"},{"key":"2025082702050591000_2016.nov22_1.bcr2016217386.9","first-page":"571","article-title":"Angioleiomyoma of the inferior nasal turbinate: a case report and review of the literature","volume":"48","author":"Melgarejo Moreno","year":"1997","journal-title":"Acta Otorrinolaringol Esp"},{"key":"2025082702050591000_2016.nov22_1.bcr2016217386.10","first-page":"1336","article-title":"Cellular leiomyoma of the nasal cavity: findings of CT and MR imaging","volume":"26","author":"Ikeda","year":"2005","journal-title":"Am J Neuroradaiol"},{"key":"2025082702050591000_2016.nov22_1.bcr2016217386.11","unstructured":"Batsakis JG .
