Computed tomographic findings in dogs with ovarian tumors: A tortuous ovarian artery consistently identifies ovarian origin in complex abdominal masses.

The aim of this retrospective multicentric case series is to describe the CT findings of ovarian neoplasia in dogs. Twenty dogs with pre- and postcontrast CT exams and cytological/histological diagnosis of ovarian neoplasia were included. Five dogs presented with bilateral tumors, for a total of 25 neoplasms: 15 carcinomas (4 bilateral), 4 granulosa cell tumors, 2 poorly differentiated malignant neoplasia (bilateral), 2 luteomas, 1 teratoma, 1 dysgerminoma.

[Clinicopathological significance of SOX2 and FOXG1 expression patterns in ovarian immature teratomas].

To investigate the relationship between the expression patterns of SOX2 and FOXG1 and the differentiation/development level of neural components in immature teratoma and to determine the clinical significance and potential application of this correlation in a clinical setting. We conducted a comprehensive whole transcriptome sequencing analysis to identify differentially expressed genes (DEGs) across various subtypes of ovarian germ cell tumors. Additionally, immunohistochemical staining of paraffin-embedded tissue sections was employed to assess the nuclear staining pattern of SOX2 and FOXG1 proteins within the tumor tissues.

Enhancing the accuracy of preoperative and intraoperative evaluation of malignant ovarian germ cell tumors with a focus on fertility preservation in young women.

Objective: To analyze and improve the accuracy of preoperative assessment and intraoperative frozen-section analysis (FSA) for malignant ovarian germ cell tumors (MOGCTs), especially in the context of fertility preservation.

Methods: A retrospective review of 48 women aged under 40 years, diagnosed with MOGCTs, and treated at Chonnam National University Hospital between July and December 2022 was conducted. The results of preoperative magnetic resonance imaging (MRI), measurement of serum tumor markers (α-fetoprotein [AFP], β-human chorionic gonadotropin, lactate dehydrogenase [LDH], cancer antigen [CA] 125, CA 19-9, CA 72-4, carcinoembryonic antigen), and intraoperative FSA were compared with the final pathology diagnosis.

Metastasis of ovarian dysgerminoma in a postmenopausal patient: a rare case report.

Ovary dysgerminoma is one of the most good prognosis malignant tumor, which has a 5-year overall survival rate exceeding to 90%. Generally, the incidence of ovarian dysgerminoma (OD) is relatively low, accounting for ~0.6% of all ovarian tumors.

Spontaneous pregnancy after fertility-sparing surgery and adjuvant chemotherapy for advanced pure dysgerminoma: A case report.

Key Clinical Message: Fertility-sparing surgery and appropriate adjuvant chemotherapy for advanced malignant ovarian germ cell tumors have excellent survival results and promising reproductive and obstetric outcomes.

Abstract: This case report aims to demonstrate the potential feasibility and success of fertility-sparing surgery (FSS) coupled with adjuvant chemotherapy in treating advanced malignant ovarian germ cell tumor (MOGCT), focusing on pure dysgerminoma, fertility, and achieving spontaneous pregnancy. The patient was a 23-year-old female who initially presented with complaints of abdominal distension and a palpable mass and was subsequently diagnosed with advanced MOGCT.

Ovarian Germ Cell Tumors in North-Western India: A Comprehensive 3-Year Retrospective Study of 145 Cases at a Tertiary Cancer Hospital.

Germ cell tumors encompass a broad spectrum of neoplasms arising from germ cell lineage, demonstrating varying histological profiles and clinical presentations. These tumors encompass a range of benign and malignant entities. While global trends provide insights into their prevalence, specific regional variations, such as those within North-Western India, remain less explored.

Comprehensive microRNA expression analysis of pediatric gonadal germ cell tumors: unveiling novel biomarkers and signatures.

microRNAs (miRNAs) are small endogenous noncoding RNAs, and alterations in their expression may contribute to oncogenesis. Discovering a unique miRNA pattern holds the potential for early detection and novel treatment possibilities in cancer. This study aimed to evaluate miRNA expression in pediatric patients with gonadal germ cell tumors (GCTs), focusing on characterizing the miRNA profiles of each histological subtype and identifying a distinct histological miRNA signature for a total of 42 samples of pediatric gonadal GCTs.
