With a slight male predisposition, it occurs more commonly in the lower extremities with an insidious and painless presentation. Contrary to the usual, our patient was with a rare presentation in the inguinal region with a dull aching pain.<\/jats:p>\n <\/jats:sec>\n \n Case presentation<\/jats:title>\n We herein report a case of a 64-year-old female patient with myopericytoma, the first of its kind reported in Nepal, present in the right inguinal region and surgically removed. The mass was single with dull aching pain, non-tender, globular, smooth, mobile, covered with skin and, had been slowly growing for 1 year and had started bleeding for 4 days. On complete surgical excision and subsequent biopsy, a nodule with thin-walled blood vessels and spindle-shaped cells having indistinct cell border, eosinophilic cytoplasm, and oval to spindle-shaped nucleus was observed, features consistent with those of myopericytoma.<\/jats:p>\n <\/jats:sec>\n \n Discussion<\/jats:title>\n Myopericytoma can occur in different sites in the body. Its differential diagnoses in the inguinal region include inguinal hernia, lipoma, or an inguinal lymphangioma. Histopathological analysis and immunohistochemistry (IHC) staining are used for diagnosis and confirmation.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Myopericytomas are rare and have a substantial propensity to be misdiagnosed as other soft tissue tumors such as sarcomas due to significant overlap in their presentation and histological features. Complete surgical excision of mass is the curative therapy.<\/jats:p>\n <\/jats:sec>\n \n Highlights<\/jats:title>\n <\/jats:sec>","DOI":"10.1016\/j.ijscr.2021.105820","type":"journal-article","created":{"date-parts":[[2021,3,23]],"date-time":"2021-03-23T15:54:26Z","timestamp":1616514866000},"page":"105820","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Myopericytoma in right inguinal region"],"prefix":"10.1097","volume":"81","author":[{"given":"Kshitiz","family":"Acharya","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Navin","family":"Poudel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aramva Bikram","family":"Adhikari","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Subarna","family":"Giri","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kanchana","family":"Bali","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naveen C.","family":"Bhatta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"R1-117-20260114","doi-asserted-by":"crossref","first-page":"338","DOI":"10.1007\/s11552-014-9647-5","article-title":"Myopericytoma of the distal forearm: a case report","volume":"10","author":"Yang","year":"2015","journal-title":"Hand"},{"key":"R2-117-20260114","first-page":"1771","article-title":"Myopericytoma of the stomach: report of one case and review of literature","volume":"13","author":"Weng","year":"2020","journal-title":"Int.
