A 46\u2010year\u2010old patient was referred to our clinic due to prolonged menstrual bleeding, without additional symptoms. Histopathological analysis of the specimens collected through exploratory curettage demonstrated the presence of uterine PEComa, characterized by positive immunohistochemical markers including HMB\u201045, TFE3, Cathepsin K, and ER. The patient underwent laparoscopic hysterectomy with bilateral adnexectomy. No recurrence of the disease was observed during the subsequent examinations. This case underscores a common diagnostic pitfall: the absence of a distinct mass on imaging. It highlights that a PEComa can present with only non\u2010specific endometrial thickening, making preoperative diagnosis exceptionally challenging and reliant on histopathology. Laparoscopic surgery in our case provided the patient with quick recovery and a less invasive approach with satisfying results and the absence of recurrent disease during a one\u2010year follow\u2010up period. Future multicenter studies should facilitate a deeper comprehension and undoubtedly lead to a more effective management of a rare and enigmatic condition that is uterine PEComa.<\/jats:p>","DOI":"10.1111\/jog.70169","type":"journal-article","created":{"date-parts":[[2025,12,13]],"date-time":"2025-12-13T01:09:57Z","timestamp":1765588197000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Perivascular Epithelioid Cell Neoplasm of the Uterus: A Case Report"],"prefix":"10.1111","volume":"51","author":[{"given":"Lazar","family":"Nejkovi\u0107","sequence":"first","affiliation":[{"name":"The Obstetrics and Gynaecology Clinic Narodni Front  Belgrade Serbia"},{"name":"School of Medicine, University of Belgrade  Belgrade Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana","family":"\u0110or\u0111evi\u0107","sequence":"additional","affiliation":[{"name":"The Obstetrics and Gynaecology Clinic Narodni Front  Belgrade Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Smiljana","family":"Doni\u0107","sequence":"additional","affiliation":[{"name":"The Obstetrics and Gynaecology Clinic Narodni Front  Belgrade Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marijana","family":"Cimbaljevi\u0107","sequence":"additional","affiliation":[{"name":"The Obstetrics and Gynaecology Clinic Narodni Front  Belgrade Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1443-0311","authenticated-orcid":false,"given":"Aleksandar","family":"Raki\u0107","sequence":"additional","affiliation":[{"name":"The Obstetrics and Gynaecology Clinic Narodni Front  Belgrade Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,12,12]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.pas.0000173232.22117.37"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmig.2009.04.014"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/jcu.22950"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.2147\/OTT.S300523"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.29116"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/gcc.22908"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1136\/jclinpath\u20102015\u2010202945"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0000000000000133"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ygyno.2024.06.007"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gore.2022.100962"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.3390\/diagnostics10080553"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.13.10909"},{"key":"e_1_2_11_14_1","doi-asserted-by":"publisher","DOI":"10.1097\/PGP.0000000000000653"},{"key":"e_1_2_11_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijsu.2015.05.002"},{"key":"e_1_2_11_16_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13256\u2010024\u201004781\u2010z"}],"container-title":["Journal of Obstetrics and Gynaecology Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jog.70169","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,12,22]],"date-time":"2025-12-22T04:03:56Z","timestamp":1766376236000},"score":1,"resource":{"primary":{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/10.1111\/jog.70169"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,12]]},"references-count":15,"journal-issue":{"issue":"12","published-print":{"date-parts":[[2025,12]]}},"alternative-id":["10.1111\/jog.70169"],"URL":"https:\/\/doi.org\/10.1111\/jog.70169","archive":["Portico"],"relation":{},"ISSN":["1341-8076","1447-0756"],"issn-type":[{"value":"1341-8076","type":"print"},{"value":"1447-0756","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,12]]},"assertion":[{"value":"2025-06-02","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-12-02","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-12-12","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e70169"}}
