A 32-year-old woman consulted for an evaluation of pelvic pain following intrauterine insemination (IUI). Vaginal and abdominal sonography, septic workup were performed and laparoscopic surgery was scheduled after failure to respond to a course of antibiotics. During laparoscopic surgery, bilateral tubo-ovarian abscesses arising on the endometriotic cysts of both ovaries were identified with a vast amount of brownish peritoneal fluid under the adhesion of the greater omentum. Bilateral ovarian cystectomy, right salpingectomy and lysis adhesion were performed...

STUDY QUESTION: Are the large cells derived from cultured DEAD box polypeptide 4 (DDX4)-positive oogonial stem cells (OSCs), isolated from the ovarian cortex of non-menopausal and menopausal women, oocyte-like cells? SUMMARY ANSWER: Under appropriate culture conditions, DDX4-positive OSCs from non-menopausal and menopausal women differentiate into large haploid oocyte-like cells expressing the major oocyte markers growth differentiation factor 9 (GDF-9) and synaptonemal complex protein 3 (SYCP3) and then enter meiosis...

Saccharin sodium and rebaudioside A are widely used as non-caloric sweeteners in our daily life; however, the impacts and regulatory mechanisms of such sweeteners on reproduction remain unclear. In the present study, we used rats as animal models to evaluate the effects of daily exposure to saccharin sodium and rebaudioside A on ovarian biologic functions. Weanling rats were distributed into five experimental groups receiving normal water, 1.5 or 7.5 mM saccharin sodium solution, or 0.5 or 2.5 mM rebaudioside A solution for 48 days of exposure...

BACKGROUND: Giant ovarian cysts are tumours of the ovary presenting with diameters greater than 10 cm. Giant ovarian cysts have become rare in recent days as they are diagnosed and managed early due to the availability of good imaging modalities. The aim of this case report is to show how a huge cystic ovarian mass can mislead the diagnosis of ascites in a postmenopausal woman. Factors associated with late presentation of giant ovarian cysts in sub-Saharan Africa have also been discussed...

INTRODUCTION: Echinococcus granulosus is a parasitic tape worm. The definitive host is the dog and humans are one of its intermediate hosts. It involves organs such as liver and lungs. Uterus involvement is very rare. PRESENTATION OF CASE: We here report a case of primary uterus hydatid cyst that we had to remove her uterine on left ovary and fallopian tube. Generalized toxic shock and infection due to cyst rupture or organ dysfunction due to invasion (like our patient) or pressure of cyst are complications of this cyst...

In female mammals, primordial follicles consist of two types of cells, namely, oocytes and pregranulosa cells that surround the oocytes. The size of the primordial follicle pool determines the reproductive ability of female mammals. However, the underlying mechanisms controlling primordial follicle assembly remain unclear. In this study, we show that oocyte-derived Janus kinase (JAK) signaling is vital for germline cyst breakdown and primordial follicle formation in vitro JAK2 and JAK3 activity is increased while germline cysts are breaking down...

Di(2-ethylhexyl) phthalate (DEHP) is a plasticizer in many consumer products. Although DEHP is a known endocrine disruptor, little is known about the effects of DEHP exposure on female reproduction. Thus, this study tested the hypothesis that prenatal DEHP exposure affects follicle numbers, estrous cyclicity, and hormone levels in multiple generations of mice. Pregnant CD-1 mice were orally dosed with corn oil (vehicle control) or DEHP (20 and 200 µg/kg/day, and 500 and 750 mg/kg/day) from gestation day 10...

BACKGROUND: Ovarian transposition is aimed at preserving ovarian function before irradiation in pelvic malignancies. The extrapelvic location of the ovaries and their physiologic fluorine-18-fluorodeoxyglucose (F-FDG)-uptake is a potential source of misdiagnosis as metastasis on F-FDG PET/CT. We describe the F-FDG PET/CT characteristics of transposed ovaries and their changes over time. PATIENTS AND METHODS: We reviewed F-FDG PET/CT studies of all consecutive women with pelvic malignancies who underwent ovarian transposition between 2007 and 2013...

Background: Having low-grade chronic inflammation such as elevated C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) plays a crucial role in polycystic ovary syndrome (PCOS). This study aimed at investigating the therapeutic effects of curcumin on IL-6, CRP and TNF-α and symptoms of polycystic ovary syndrome. Methods: In this research, 72 female adult Wistar rats were divided into control (n=12), PCOS (n=12) and curcumin-treated PCOS groups (n=48)...

AIMS: Evidence suggests that up to 70% of high-grade serous ovarian carcinomas (HGSCs) potentially arise from fallopian tube fimbriae, and that many of the remaining cases arise from within the ovary in cortical inclusion cysts (CICs) with a Müllerian phenotype (Müllerian-CICs). It has been proposed that Müllerian-CICs arise either from metaplasia of mesothelial ovarian surface epithelium (OSE) entrapped within the ovary after ovulation, or from normal tubal cells entrapped post-ovulation...

BACKGROUND: Plasmablastic lymphoma (PBL) is relatively new clinical entity described as a distinct subtype of diffuse large B-cell lymphoma (DLBCL). It is characterized by its aggressive nature and proliferation of large neoplastic cells resembling immunoblasts including cells with more obvious plasmacytic differentiation. In this case report, we describe an unexpected finding of PBL associated with a mature cystic teratoma of the ovary in a young immune competent woman. CASE PRESENTATION: A 19-year old woman was admitted to the hospital with generalized lymphadenopathy, a pelvic tumor mass measuring 35 × 30 cm and a 4 cm lump in her right breast...

A 74-year-old postmenopausal woman visited our gynecology clinic complaining of a palpable abdominal mass. Physical and radiological evaluation indicated that the mass exhibited features of a left ovarian neoplasm showing heterogeneous enhancement. Surgical resection was performed to confirm this suspicion. During surgery, a mass was observed only in the left ovary with no invasive growth, but adhesions to the surrounding peritoneum were seen. Given the patient's age, large mass size, and accompanying uterine myoma and right ovarian cyst, total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed...

The genus Grania comprises over 70 species of exclusively marine clitellate annelids belonging to the family Enchytraeidae. Morphologically, this genus is well separated from other enchytraeids, with thick cuticles, anterior segments I-IV fused into a "head", chaetal bundles consisting only of one stout chaeta, and reduction of circular musculature. The aim of the present study is to describe the ovary organization and the course of oogenesis in Grania postclitellochaeta, and to compare it with other known systems of ovary organization and oogenesis in clitellate annelids, especially in enchytraeids...

We report the case of a 33-year-old woman who went under surgery for a cystic mature teratoma. The histological exam found two cysts, one was a mature teratoma and the other was a struma ovarii with a papillary carcinomatous element. Struma ovarii cancerization is seen in 5 to 10% of the cases usually under a papillary carcinoma type. Diagnosis is rarely made before surgery, the patients exceptionally show thyroid symptoms. Histologically, the tumour presents the same way as the one seen in the thyroid gland and BRAF mutations have been reported...

A 32-year-old woman, who presented for laparoscopic sterilization after two full-term normal deliveries, was incidentally diagnosed to have a left-sided complex cyst in the pouch of Douglas (POD). She had no history of previous surgeries or any symptoms of lower abdominal pain, nausea, or vomiting in the past. She underwent laparoscopy, and the left ovary and distal portion of the fallopian tube were absent in their normal position. An ectopic left ovary with dermoid cyst was noted in the POD. The right ovary and tube were in their normal position...

Among female infants, a mass in the abdomen carries a large number of differential diagnoses. Arelatively uncommon condition is ovarian cyst, which may be encountered among such patients. Even more rare condition is auto-amputation of ovary. We herein, present a case of a female infant who presented as abdominal mass and turned out to be autoamputation of right ovary attached to mesentery of intestine. It was excised successfully and the patient is doing well at 3 years follow-up.

Genital tuberculosis mimicking carcinoma ovary is a well-known dilemma as there is no definitive serological or imaging modality for diagnosing abdominopelvic tuberculosis. A 20-years-old unmarried girl presented with complex adnexal mass, mild ascites and CA 125 >1000. Her staging laparotomy and frozen section was planned. Laparotomy revealed miliary tuberculosis and frozen section confirmed the diagnosis of tuberculosis. Patient was started with anti-tuberculosis treatment and follow up showed resolution of cysts...
