The main histological types of cervical cancer are squamous cell carcinoma\u201475% of all cases; adenocarcinoma\u201410\u201325%; and all other rare variants including adenosquamous carcinoma and neuroendocrine carcinoma. Squamotransitional cervical cancer is an extremely rare and poorly studied subtype of squamous cell carcinoma. Case report: We present a case of a 64-year-old female patient with early-stage squamotransitional carcinoma. A metastasis was observed in the left ovary and the left fallopian tube and a benign Brenner tumor in the right ovary. Discussion: Although it is believed that this cervical cancer subtype shares the same risk factors and prognosis as squamous cell carcinoma, it is more likely to metastasize and recur. It is not unusual for spread to exist within nearby structures like the cervix and adnexa. It is impossible to tell which is the predominant focus from the immunoprofile of the lesions. Practically speaking, the best course of action in these situations is to rule out the presence of a primary tumor in the urinary tract before clarifying the condition of the cervix, uterus, and adnexal tissues. The presence of a Brenner tumor raises the possibility of a connection between the tumor\u2019s differentiation from a cell population and potential urothelial differentiation. Conclusion: Squamotransitional cervical cancer is a rare tumor with a poorly studied clinical behavior. Despite a shortage of information in the literature, it should be regarded as a more aggressive variety of squamous cell carcinoma and, as such, should be treated and followed up more aggressively. This case is the first described with involvement of the cervix, endometrium, and adnexal structures and a concomitant Brenner tumor.<\/jats:p>","DOI":"10.3390\/reports6040054","type":"journal-article","created":{"date-parts":[[2023,11,14]],"date-time":"2023-11-14T02:20:37Z","timestamp":1699928437000},"page":"54","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Squamotransitional Cell Carcinoma of the Uterine Cervix with Ovarian Metastasis and Benign Brenner Tumor: A Case Report"],"prefix":"10.3390","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7719-382X","authenticated-orcid":false,"given":"Angel","family":"Yordanov","sequence":"first","affiliation":[{"name":"Department of Gynaecological Oncology, Medical University Pleven, 5800 Pleven, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Milen","family":"Karaivanov","sequence":"additional","affiliation":[{"name":"Department of General and Clinical Pathology, University Hospital \u201cDr. Georgi Stranski\u201d, 5800 Pleven, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ivan","family":"Ivanov","sequence":"additional","affiliation":[{"name":"Department of General and Clinical Pathology, University Hospital \u201cDr. Georgi Stranski\u201d, 5800 Pleven, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5279-3095","authenticated-orcid":false,"given":"Stoyan","family":"Kostov","sequence":"additional","affiliation":[{"name":"Department of Gynecology, St. Anna University Hospital, Medical University\u2014Varna \u201cProf. Dr. Paraskev Stoyanov\u201d, 9000 Varna, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Venelina","family":"Todorova","sequence":"additional","affiliation":[{"name":"Imaging Department, University Hospital \u201cDr. Georgi Stranski\u201d, 5800 Pleven, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ilko","family":"Iliev","sequence":"additional","affiliation":[{"name":"Department of Gynaecological Oncology, Medical University Pleven, 5800 Pleven, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eva","family":"Tzoneva","sequence":"additional","affiliation":[{"name":"\u201cDr. Shterev\u201d Hospital, 1000 Sofia, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Diana","family":"Strateva","sequence":"additional","affiliation":[{"name":"Department of Gynaecological Oncology, Medical University Pleven, 5800 Pleven, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"555","DOI":"10.1016\/j.ygyno.2021.06.029","article-title":"The New Mexico HPV Pap Registry Steering Committee.
