Genome-wide analyses have recently been reported for ovarian cancer. High-grade serous ovarian carcinoma(HGSOC) almost exclusively harbor TP53 mutations and prominent copy number aberrations. Approximately 20% of HGSOCs harbor BRCA mutations, in which case PARP inhibitors may be effective. HGSOCs are classified into 4 molecular subtypes with distinct histopathological features by transcriptional profiling. These subtypes differ in prognosis and drug sensitivity. Additionally, a whole-genome analysis for HGSOC has revealed various factors that can induce resistance to chemotherapy...

Background Ovarian cysts, which present as neoplastic and non-neoplastic lesions, are the most common gynaecological cause of hospital admissions. Early diagnosis is difficult due to asymptomatic nature. Clinical, radiological and gross examination alone cannot distinguish benign from malignant lesions, hence, histopathological examination is important for diagnostic, therapeutic and prognostic approach. Objective The objective of the study is to analyze the spectrum of ovarian cystic lesions with their clinico-morphorgical features...

Hydatid disease, caused by the larval stage of Echinococcus granulosus, is found most commonly in the liver and lungs, but no organ is immune. The ovarian involvement is often secondary to a cyst's dissemination localized in a different site. Occasionally, the cyst enlarges, thus mimicking an ovarian tumor. Patients with hydatid cysts at unusual locations present with atypical presentations and pose a diagnostic dilemma. A high index of suspicion is required in order to make a correct diagnosis pre-operatively to prevent spillage of the cyst contents during surgery...

This study aimed to investigate the potential detrimental effect of human endometriotic fluids (EFs) on in vitro growth of mouse preantral follicles. Preantral follicles (isolated from ovaries of 7- to 8-week-old mice) were cultured in growth medium for 10 days and then in maturation medium for 2 days. During in vitro culture, EF supernatants (0%, 2.5%, 5%, and 10%) were supplemented. Meiotic spindle integrity of metaphase II (MII) oocytes was analyzed. Hormone (17β-estradiol and anti-Müllerian hormone [AMH]) levels in the final spent media were measured by enzyme-linked immunosorbent assay...

Previous work has demonstrated that the increase in the activity of sympathetic nerves, which occurs during the subfertility period in female rats, causes an increase in follicular cyst development and impairs follicular development. In addition, the increase in ovarian sympathetic activity of aged rats correlates with an increased expression of kisspeptin (KISS1) in the ovary. This increase in KISS1 could participate in the decrease in follicular development that occurs during the subfertility period. We aimed to determine whether the blockade of ovarian sympathetic tone prevents the increase in KISS1 expression during reproductive aging and improves follicular development...

Borderline Brenner tumors represent quite a rare entity of ovarian tumors (about 2%) that develop from the surface ovarian epithelium. They are formed from papillary structures made of fibrovascular conjunctive axes covered by a transition epithelium, similar to the urinary bladder epithelium. According to the WHO classification, Brenner tumors present the following forms: benign, borderline and malignant. The benign ones are the most frequent, representing about 95%, the borderline represent about 5%, and the malignant ones less than 1%...

NHERF1 is an adaptor protein expressed in the apical membrane of polarized epithelia, which interacts with the EZRIN-Radixin-Moesin (ERM) family of proteins connecting signaling pathways to the cell cytoskeleton. NHERF1 and EZRIN cooperate in the maintenance of the apical microvilli in polarized epithelial cells. In several types of cancers, NHERF1 and EZRIN are displaced from the apical compartment to the cytoplasm and nuclei of cancer cells. At the present, the distribution of NHERF1 in ovarian tumors is not well known...

Purpose. Torsion of the fallopian tube, involving hydatids of Morgagni, though a rare cause of acute pelvic pain in young girls, can pose significant risks to future fertility. Tubal torsion may present as a diagnostic dilemma since the ovary itself usually appears normal on ultrasound. Thus, surgical intervention may be delayed which can lead to worsening necrosis and result in the need for resection of the affected tube. Methods. We reviewed two cases of fallopian tube torsion associated with hydatids of Morgagni in adolescent females...

Introduction. Carcinosarcoma is an uncommon form of ovarian cancers, classified as being part of the group of mixed epithelial and mesenchymal tumors. The occurrence of carcinosarcoma in association with a mature cystic teratoma and synchronous tubal carcinoma is very rare. Case Report. A 69-year-old woman presented with a pelvic mass. An abdominal computerized tomographic scan detected a 15 cm right pelvic mass which was suggestive of malignant transformation of a dermoid cyst. Intraoperative, bilateral ovarian masses (left 10 cm and right 12 cm) with diffuse peritoneal metastatic nodules were identified...

BACKGROUND: Polycystic ovarian syndrome (PCOS), one of the leading causes of infertility seen in women, is characterized by anovulation and hyperandrogenism, resulting in ovarian dysfunction. In addition, associations of several metabolic complications like insulin resistance, obesity, dyslipidemia and psychological co-morbidities are well known in PCOS. One of the major factors influencing mood and the emotional state of mind is neurotransmitters. Also, these neurotransmitters are very crucial for GnRH release...
