They affect various anatomic sites, kidneys being one of them. Renal PEComas are further rare, posing a challenge to include them in the differential diagnoses. We present a case of a type of renal PEComa in a 54-year old post-menopausal female with vague abdominal pain. Imaging revealed a large left perinephric mass initially suspected to be a liposarcoma. Surgical excision and subsequent histopathological evaluation confirmed a benign, fat predominant renal angiomyolipoma. This case depicts the mimicking and heterogenous nature of PEComas and the importance of early detection followed by appropriate treatment.<\/jats:p>","DOI":"10.1093\/jscr\/rjag215","type":"journal-article","created":{"date-parts":[[2026,3,17]],"date-time":"2026-03-17T12:37:35Z","timestamp":1773751055000},"source":"Crossref","is-referenced-by-count":1,"title":["From the spectrum of PEComa: a renal angiomyolipoma"],"prefix":"10.1093","volume":"2026","author":[{"given":"Shuvi V","family":"Kamble","sequence":"first","affiliation":[{"name":"Mohammed Bin Rashid University of Medicine and Health Sciences , Dubai 505055 ,","place":["United Arab Emirates"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammad U","family":"Younis","sequence":"additional","affiliation":[{"name":"General Surgery, Mediclinic City Hospital , Dubai 505004 ,","place":["United Arab Emirates"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hemant J","family":"Vadeyar","sequence":"additional","affiliation":[{"name":"General Surgery, Mediclinic City Hospital , Dubai 505004 ,","place":["United Arab Emirates"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,4,4]]},"reference":[{"key":"2026040410402869200_ref1","article-title":"Perivascular epithelioid cell tumors (PEComas) of the bone and soft tissue: a Japanese musculoskeletal oncology group (JMOG) multi-institutional study","volume":"149","author":"Yuya","journal-title":"J Cancer Res Clin Oncol"},{"key":"2026040410402869200_ref2","doi-asserted-by":"publisher","first-page":"102890","DOI":"10.1016\/j.eucr.2024.102890","article-title":"Renal PEComa in a young male: a case report and insights from the literature","volume":"58","author":"Sholan","year":"2025","journal-title":"Urol Case Rep"},{"key":"2026040410402869200_ref3","volume-title":"Perivascular epithelioid cell neoplasm - symptoms, causes, treatment","author":"Andrew","year":"2022"},{"key":"2026040410402869200_ref4","doi-asserted-by":"publisher","first-page":"119","DOI":"10.1007\/s00428-007-0509-1","article-title":"PEComas: the past, the present and the future","volume":"452","author":"Martignoni","year":"2008","journal-title":"Springer Nat"},{"key":"2026040410402869200_ref5","doi-asserted-by":"publisher","first-page":"110332","DOI":"10.1016\/j.clinimag.2024.110332","article-title":"PEComas: a review of imaging and clinical features","volume":"116","author":"Kinzel","year":"2024","journal-title":"Clin Imaging"},{"key":"2026040410402869200_ref6","doi-asserted-by":"publisher","first-page":"372","DOI":"10.14740\/wjon1794","article-title":"Comprehensive insights into renal perivascular epithelioid cell neoplasms: from molecular mechanisms to clinical practice.
