With hormonal changes and enlargement of the uterus during pregnancy, tumors can also increase the chance of rupture and consequent SHiP. We report a case of a 30\u2010year\u2010old primiparous woman presented with sudden\u2010onset intraabdominal hemorrhage at 34 weeks\u2019 gestation. The source of bleeding was rupture of a perivascular epithelioid cell neoplasm on the left round ligament of the uterus. The pregnancy ended with an uncomplicated, full\u2010term, vaginal delivery. We performed an additional post\u2010partum surgery to resect the left round ligament and transposition of the right ovary. In cases of SHiP, the possibility of a nonendometriosis origin should be considered. Preoperative imaging and histologic examinations of bleeding lesions are crucial for managing SHiP.<\/jats:p>","DOI":"10.1111\/jog.13870","type":"journal-article","created":{"date-parts":[[2018,12,12]],"date-time":"2018-12-12T08:40:11Z","timestamp":1544604011000},"page":"709-713","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Rupture
