When malignant, they can be aggressive with local invasion and metastatic spread. Conventional PEComas do not have TFE3 gene rearrangement and are associated with TSC with a preference for an occurrence at a younger age. We report a case of a young male who had progressive chronic hip pain and was found to have a TFE3-associated PEComa in his pelvic region.<\/jats:p>","DOI":"10.1177\/23247096221103385","type":"journal-article","created":{"date-parts":[[2022,6,14]],"date-time":"2022-06-14T07:11:15Z","timestamp":1655190675000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["A Rare Cause of Chronic Hip Pain From PEComa: An Aggressive Mesenchymal Sarcoma"],"prefix":"10.1177","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5382-8245","authenticated-orcid":false,"given":"Samender","family":"Randhawa","sequence":"first","affiliation":[{"name":"State University of New York Upstate Medical University, Syracuse, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jessica","family":"Pinsker","sequence":"additional","affiliation":[{"name":"State University of New York Upstate Medical University, Syracuse, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Madhurya","family":"Amirapu","sequence":"additional","affiliation":[{"name":"State University of New York Upstate Medical University, Syracuse, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5051-6991","authenticated-orcid":false,"given":"Metlapalli Venkata","family":"Sravanthi","sequence":"additional","affiliation":[{"name":"State University of New York Upstate Medical University, Syracuse, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6236-2822","authenticated-orcid":false,"given":"Prashanth","family":"Ashok Kumar","sequence":"additional","affiliation":[{"name":"State University of New York Upstate Medical University, Syracuse, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Komal","family":"Akhtar","sequence":"additional","affiliation":[{"name":"State University of New York Upstate Medical University, Syracuse, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2022,6,14]]},"reference":[{"key":"bibr1-23247096221103385","volume-title":"WHO Classification of Tumours of Soft Tissue and Bone","author":"Doyle LA","year":"2020","edition":"5"},{"key":"bibr2-23247096221103385","doi-asserted-by":"publisher","DOI":"10.5603\/OCP.2020.0003"},{"key":"bibr3-23247096221103385","doi-asserted-by":"publisher","DOI":"10.1159\/000510241"},{"key":"bibr4-23247096221103385","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0b013e31824a8a37"},{"key":"bibr5-23247096221103385","doi-asserted-by":"publisher","DOI":"10.1016\/j.anndiagpath.2015.06.003."},{"key":"bibr6-23247096221103385","doi-asserted-by":"publisher","DOI":"10.1097\/01.pas.0000173232.22117.37"},{"key":"bibr7-23247096221103385","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0b013e3181f17ac0"},{"key":"bibr8-23247096221103385","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0000000000000389"},{"key":"bibr9-23247096221103385","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.21.01728"},{"key":"bibr10-23247096221103385","unstructured":"FDA resources page.
