Multimodality Imaging Approach to Ovarian Neoplasms with Pathologic Correlation.

Radiographics 2021 Jan-Feb;41(1):289-315. Epub 2020 Nov 13.

From the Department of Radiology and Biomedical Imaging (E.C.T., M.M.) and Department of Pathology (L.I.), Yale School of Medicine, 333 Cedar St, PO Box 208042, Room TE-2, New Haven, CT 06520.

Ovarian neoplasms can be categorized on the basis of histopathologic features into epithelial surface cell tumors, germ cell tumors, sex cord-stromal tumors, and metastases. While their imaging appearance is often nonspecific, it closely parallels the gross pathologic appearance, and radiologic-pathologic correlation is helpful to aid in a deeper understanding of the subtypes. Epithelial cell neoplasms are the most common category, and they can be benign, borderline, or malignant. Read More

Gonadoblastoma versus ovarian mixed germ cell-sex cord stromal tumor in women or girls with no evidence of a disorder of sex development: A problem in differential diagnosis.

Pathol Res Pract 2020 Nov 5;216(11):153198. Epub 2020 Sep 5.

Department of Pathology and Laboratory Medicine, Indiana University School of Medicine, Van Nuys Medical Science Building 128, 635 Barnhill Drive, Indianapolis, IN 46240-5120, United States; Department of Urology, Indiana University School of Medicine, Indianapolis, IN 46240-5120, United States.

Gonadoblastoma occurring in a normal girl or woman has been confused with ovarian mixed germ cell-sex cord stromal tumor (MGC-SCST) due to a lack of knowledge that the former occurs occasionally in a normal woman or girl. In this article, we develop histological criteria that facilitate the distinction of gonadoblastoma in an individual with a normal karyotype and no evidence of a disorder of sex development from ovarian MGC-SCST. We reviewed the histological findings of gonadoblastoma occurring in normal individuals and compared them to cases of ovarian MGC-SCST in our files. Read More

Rare DICER1 and Absent FOXL2 Mutations Characterize Ovarian Juvenile Granulosa Cell Tumors.

Am J Surg Pathol 2021 02;45(2):223-229

Departments of Pathology.

FOXL2 somatic mutation occurs in a high percentage of ovarian adult granulosa cell tumors and DICER1 mutations in a high proportion of Sertoli-Leydig cell tumors. These mutations have only been studied in a limited number of juvenile granulosa cell tumors (JGCTs), and their occurrence and frequency in these neoplasms is controversial. We aimed to determine the frequency of FOXL2 and DICER1 mutations in a large cohort of 50 JGCTs, and to evaluate the prognostic impact of these mutations. Read More

Ovarian granulosa cell tumor characterization identifies FOXL2 as an immunotherapeutic target.

JCI Insight 2020 08 20;5(16). Epub 2020 Aug 20.

Department of Radiation Oncology and.

Granulosa cell tumors (GCT) are rare ovarian malignancies. Due to the lack of effective treatment in late relapse, there is a clear unmet need for novel therapies. Forkhead Box L2 (FOXL2) is a protein mainly expressed in granulosa cells (GC) and therefore is a rational therapeutic target. Read More

CircPSMC3 alleviates the symptoms of PCOS by sponging miR-296-3p and regulating PTEN expression.

J Cell Mol Med 2020 09 17;24(18):11001-11011. Epub 2020 Aug 17.

Reproductive Medical Center, Renmin Hospital, Wuhan University, Wuhan, China.

Polycystic ovary syndrome (PCOS), the most common female endocrine disease that causes anovulatory infertility, still lacks promising strategy for the accurate diagnosis and effective therapeutics of PCOS attributed to its unclear aetiology. In this study, we determined the abnormal reduction in circPSMC3 expression by comparing the ovarian tissue samples of PCOS patients and normal individuals. The symptom relief caused by up-regulation of circPSMC3 in PCOS model mice suggested the potential for further study. Read More

Ovarian Gynandroblastoma with a Juvenile Granulosa Cell Tumor Component in a Postmenopausal Woman.

Diagnostics (Basel) 2020 Jul 30;10(8). Epub 2020 Jul 30.

Department of Pathology and Translational Genomics, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 06351, Korea.

Ovarian gynandroblastoma (GAB) is an extremely rare sex cord-stromal tumor showing morphological evidence of both female (granulosa cell tumor) and male (Sertoli-Leydig cell tumor (SLCT)) components. Almost all GAB cases have been reported in children, adolescents, or women of reproductive age, and most of them typically have adult granulosa cell tumors as the female component. In contrast, GAB with a juvenile granulosa cell tumor (JGCT) component is a very rare condition; to the best of our knowledge, only one case of GAB with JGCT in a postmenopausal woman has been reported.

Epidemiology of ovarian cancer.

Chin Clin Oncol 2020 Aug 30;9(4):47. Epub 2020 Jun 30.

Department of Surgery, Section of Gynecology, National Institute of Medical Sciences and Nutrition "Salvador Zubirán", Mexico City, Mexico.

Worldwide, ovarian cancer (OC) is the seventh most common type of malignant neoplasm in women and the eighth cause of mortality in them. The classification of OC is made by the possible origin of one of the three main components of the ovary: epithelium, stroma, and germinal cells. Due to this the main malignant tumors arising from the ovary are epithelial carcinoma, germ cell tumor, sex cord-stromal tumor, and Krukenberg's tumor. Read More

Mutant FOXL2 Hijacks SMAD4 and SMAD2/3 to Drive Adult Granulosa Cell Tumors.

Cancer Res 2020 09 8;80(17):3466-3479. Epub 2020 Jul 8.

Biotech Research and Innovation Centre (BRIC), University of Copenhagen, Copenhagen N, Denmark.

The mutant protein FOXL2 is expressed in at least 95% of adult-type ovarian granulosa cell tumors (AGCT) and is considered to be a driver of oncogenesis in this disease. However, the molecular mechanism by which FOXL2 contributes to tumorigenesis is not known. Here, we show that mutant FOXL2 acquires the ability to bind SMAD4, forming a FOXL2/SMAD4/SMAD2/3 complex that binds a novel hybrid DNA motif AGHCAHAA, unique to the FOXL2 mutant. Read More
