Benign or malignant somatic neoplasms developing within teratomas can arise from any tissue in up to 2% of mature cystic teratomas, including low-grade malignant mucinous neoplasms. This report presents the case of a 34-year-old woman with no previous gynecological or general health issues, who was admitted to our Hospital after an asymptomatic pelvic mass was detected during a routine exam. A transvaginal ultrasound revealed a unilateral pelvic mass in the left adnexal region, measuring 8 cm. The CT scan showed a cystic-appearing formation measuring nearly 12 cm, which indented the bladder dome. Final diagnosis indicated a mucinous carcinoma arising from a mucinous borderline lesion within the context of a mature ovarian teratoma. No other involvement or lymphadenopathies were detected on 18FDG-PET CT scan, and the patient is now well and free of recurrences.<\/jats:p>","DOI":"10.3390\/diagnostics15151957","type":"journal-article","created":{"date-parts":[[2025,8,4]],"date-time":"2025-08-04T15:30:06Z","timestamp":1754321406000},"page":"1957","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Mucinous Carcinoma, Mucinous Borderline Tumor and Pseudomyxoma Ovarii in a Cystic Teratoma: A Histological Conundrum"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5313-0971","authenticated-orcid":false,"given":"Cinzia","family":"Giacometti","sequence":"first","affiliation":[{"name":"Pathology Unit, Pederzoli Hospital, Peschiera del Garda, 37019 Verona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mariateresa","family":"Mirandola","sequence":"additional","affiliation":[{"name":"Gynecology & Obstetrics Unit, Pederzoli Hospital, Peschiera del Garda, 37019 Verona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Camillo","family":"Aliberti","sequence":"additional","affiliation":[{"name":"Radiology Unit, Pederzoli Hospital, Peschiera del Garda, 37019 Verona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0635-5059","authenticated-orcid":false,"given":"Filippo","family":"Molinari","sequence":"additional","affiliation":[{"name":"Academic Unit of Obstetrics and Gynecology, IRCSS Hospital Polyclinic San Martino, 16132 Genoa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisa","family":"Marcolini","sequence":"additional","affiliation":[{"name":"Pathology Unit, Pederzoli Hospital, Peschiera del Garda, 37019 Verona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniele","family":"Mautone","sequence":"additional","affiliation":[{"name":"Gynecology & Obstetrics Unit, Pederzoli Hospital, Peschiera del Garda, 37019 Verona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guido","family":"Martignoni","sequence":"additional","affiliation":[{"name":"Pathology Unit, Pederzoli Hospital, Peschiera del Garda, 37019 Verona, Italy"},{"name":"Pathology Unit, Department of Diagnostic and Public Health, University of Verona, 37126 Verona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"152494","DOI":"10.1016\/j.anndiagpath.2025.152494","article-title":"Mucinous neoplasms associated with mature cystic teratomas: A clinicopathologic study of 50 cases: Are we ready for nomenclature change?","volume":"78","author":"Ramalingam","year":"2025","journal-title":"Ann.
