An abdominal CT scan revealed a large (207 \u00d7 155 \u00d7 182 mm) thin-walled inhomogeneous tumor connected to the uterus and right ovary. Emergency surgery laparotomy was performed. Inside the abdominal cavity, a 30 \u00d7 30 cm heterogenous, dark blue tumor in the right adnexa area, torsed two times, weighing 3700 g was found. Histological examination revealed right ovary clear cell carcinoma. We emphasize the rare nature of the histology and presentation of this case report. Ovarian clear cell carcinomas are relatively rare malignancies, presenting in 5 to 10% of ovarian malignant tumors in the west.<\/jats:p>","DOI":"10.3390\/medicina58010089","type":"journal-article","created":{"date-parts":[[2022,1,7]],"date-time":"2022-01-07T03:46:27Z","timestamp":1641527187000},"page":"89","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Acute Presentation of Large Size Clear Cell Ovarian Carcinoma as Double Torsed Ovarian Tumor"],"prefix":"10.3390","volume":"58","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4522-0600","authenticated-orcid":false,"given":"Diana","family":"Bu\u017einskien\u0117","sequence":"first","affiliation":[{"name":"Faculty of Medicine, Vilnius University, LT-03101 Vilnius, Lithuania"},{"name":"Center of Obstetrics and Gynecology, Vilnius University Hospital Santaros Klinikos, LT-08661 Vilnius, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vilius","family":"Rudaitis","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Vilnius University, LT-03101 Vilnius, Lithuania"},{"name":"Center of Obstetrics and Gynecology, Vilnius University Hospital Santaros Klinikos, LT-08661 Vilnius, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karolina","family":"Misevi\u010di\u016bt\u0117","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Vilnius University, LT-03101 Vilnius, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"10","DOI":"10.3322\/caac.20138","article-title":"Cancer statistics, 2012","volume":"62","author":"Siegel","year":"2012","journal-title":"CA Cancer J.
