Atypical leiomyomas (synonyms: pleomorphic leiomyomas, leiomyomas with bizarre nuclei, bizarre leiomyomas, or symplastic leiomyomas) are a rare subtype of leiomyomas, characterized by cells with bizarre, pleomorphic\u2010appearing nuclei without (or with extremely low) associated mitotic activity. Despite the cytologic appearance, such tumors have a benign clinical course. Although there are cases of leiomyomas appearing outside the uterus in a background of endometriosis, cases specifically of atypical leiomyomas in this setting are exceptionally rare. We present a case of an atypical leiomyoma arising from pararectal endometriosis in a patient presenting with endometriosis\u2010associated primary ovarian clear cell carcinoma, metastasis to the bladder peritoneum, and a peri\u2010intestinal lymph node, in addition to a concurrent ovarian fibroma.<\/jats:p>","DOI":"10.1155\/crip\/7026230","type":"journal-article","created":{"date-parts":[[2025,9,8]],"date-time":"2025-09-08T21:49:44Z","timestamp":1757368184000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Atypical (Symplastic) Leiomyoma Arising in Pararectal Endometriosis Associated With Metastatic Ovarian Clear Cell Carcinoma: A Case Report"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1409-2199","authenticated-orcid":false,"given":"Nicholas","family":"Boivin","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ciaran","family":"Mannion","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,9,8]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.4293\/JSLS.2019.00038"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2559.2000.00845.x"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-199803000-00008"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejogrb.2021.08.006"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1177\/1066896913501385"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmig.2008.03.002"},{"key":"e_1_2_9_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.crwh.2017.08.001"},{"key":"e_1_2_9_8_2","first-page":"218","article-title":"Leiomyosarcoma of the Ovary","volume":"85","author":"Reddy S.
