A 48-year-old man with sinonasal mass presented with nasal obstruction and occasional epistaxis. Nasal endoscopy showed a readily bleeding mass in the left nasal cavity. Endoscopic removal of the mass was done. The histopathology came out to be hemangiopericytoma. The patient was kept on follow-up, and no metastasis or recurrence was seen in last 1 year. Hemangiopericytoma is a very rare vascular tumor. Surgery is the mainstay treatment of choice. A long-term follow-up is needed after surgery to rule out recurrence and metastasis. <\/jats:p>","DOI":"10.1177\/2050313x231173787","type":"journal-article","created":{"date-parts":[[2023,5,30]],"date-time":"2023-05-30T06:10:08Z","timestamp":1685427008000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Sinonasal hemangiopericytoma: A rare sinonasal tumor"],"prefix":"10.1177","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4981-1950","authenticated-orcid":false,"given":"Apar","family":"Pokharel","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology and Head and Neck Surgery, College of Medical Sciences, Chitwan, Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sabina","family":"Rai","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology and Head and Neck Surgery, Korea-Nepal Friendship Hospital, Bhaktapur, Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alina","family":"Baral","sequence":"additional","affiliation":[{"name":"Department of Pathology, College of Medical Sciences, Chitwan, Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,5,29]]},"reference":[{"issue":"3","key":"bibr1-2050313X231173787","first-page":"274","volume":"37","author":"Maresi E","year":"2007","journal-title":"Ann Clin Lab Sci"},{"issue":"3","key":"bibr2-2050313X231173787","first-page":"251","volume":"35","author":"Peyvandi A","year":"2010","journal-title":"Iran J Med Sci"},{"key":"bibr3-2050313X231173787","first-page":"796713","volume":"2013","author":"Ledderose GJ","year":"2013","journal-title":"Case Rep Otolaryngol"},{"key":"bibr4-2050313X231173787","doi-asserted-by":"publisher","DOI":"10.4103\/0973-029X.157214"},{"key":"bibr5-2050313X231173787","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2559.2002.01396.x"},{"key":"bibr6-2050313X231173787","doi-asserted-by":"publisher","DOI":"10.4103\/0973-029X.42194"},{"key":"bibr7-2050313X231173787","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijscr.2022.107241"},{"key":"bibr8-2050313X231173787","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejenta.2013.04.004"},{"key":"bibr9-2050313X231173787","doi-asserted-by":"publisher","DOI":"10.1258\/00222150260369525"},{"key":"bibr10-2050313X231173787","doi-asserted-by":"publisher","DOI":"10.1007\/PL00006046"},{"key":"bibr11-2050313X231173787","doi-asserted-by":"publisher","DOI":"10.1007\/s12105-016-0686-9"},{"key":"bibr12-2050313X231173787","first-page":"21","volume-title":"Allergens and allergen immunotherapy","author":"Cohen SG","year":"2004","edition":"3"},{"key":"bibr13-2050313X231173787","doi-asserted-by":"publisher","DOI":"10.1093\/jscr\/rjx202"},{"key":"bibr14-2050313X231173787","doi-asserted-by":"publisher","DOI":"10.1002\/hed.23074"},{"issue":"15","key":"bibr15-2050313X231173787","first-page":"157","volume":"4","author":"Manea C","year":"2014","journal-title":"Rom J Rhinol"}],"container-title":["SAGE Open Medical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2050313X231173787","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/2050313X231173787","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2050313X231173787","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,1]],"date-time":"2025-03-01T16:40:29Z","timestamp":1740847229000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/2050313X231173787"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,1]]},"references-count":15,"alternative-id":["10.1177\/2050313X231173787"],"URL":"https:\/\/doi.org\/10.1177\/2050313x231173787","relation":{},"ISSN":["2050-313X","2050-313X"],"issn-type":[{"value":"2050-313X","type":"print"},{"value":"2050-313X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,1]]},"article-number":"2050313X231173787"}}
