Adenomatoid tumors (ATs) are rare, benign neoplasms occurring mainly in reproductive organs such as the uterus, ovaries, fallopian tubes, and testes. Uterine adenomatoid tumors (UATs) are generally incidentally diagnosed during histopathological examination of excisional biopsies performed for other indications, most commonly uterine leiomyomas. We herein present a 38-year-old woman who underwent laparoscopic excision of a uterine leiomyoma and a right ovarian teratoma. Microscopic examination of the excisional biopsy revealed that the enucleated uterine tumor was composed of proliferating glandular tissue covered with single-layered cells that were surrounded by proliferating smooth muscle cells, corresponding exactly to the features of UATs...

A 19-year-old woman with a history of isosexual precocious puberty and bilateral oophorectomy at age 10 years because of giant ovarian cysts, presents with headaches and mild symptoms and signs of hyperthyroidism. Hormonal evaluation revealed elevated FSH and LH levels in the postmenopausal range and free hyperthyroxinemia with an inappropriately normal TSH. Pituitary MRI showed a 2-cm macroadenoma with suprasellar extension. She underwent successful surgical resection of the pituitary tumor, which proved to be composed of two distinct populations of cells, each of them strongly immunoreactive for FSH and TSH, respectively...

BACKGROUND: We previously showed that microRNA-503 (miR-503) transfection into endometriotic cyst stromal cells (ECSCs) induced cell cycle arrest at the G0/G1 phase by suppressing cyclin D1. This finding prompted us to evaluate the potential therapeutic effects of cyclin D1 inhibitors in endometriotic cells. This study aimed to determine whether arcyriaflavin A, a representative inhibitor of cyclin D1-cyclin-dependent kinase 4 (CDK4), is beneficial in the treatment of endometriosis. METHODS: ECSCs were isolated from the ovarian endometriotic tissues of 32 women...

Virilizing ovarian dermoid cysts are very rare. The source of androgen in these cysts may be tumors such as Sertoli-Leydig cell tumor or Leydig cell hyperplasia. A 52-year-old postmenopausal female with virilization was found to have an ovarian dermoid cyst on ultrasound. Her serum testosterone levels were elevated. Leydig cell hyperplasia within the dermoid cyst was found to be the source of androgen in this patient.

Hydatid disease is a parasitic infection that most commonly affects the liver and lungs, although the disease can arise in any part of the body. Cysts may mimic many benign and malignant conditions. The diagnosis cannot be confirmed preoperatively in all cases. A 44-yr-old menopausal woman was admitted to the department of gynecology with complaints of abdominal distention. A fixed abdominopelvic mass was identified. Radiology revealed a 20-cm mass with branched septations and solid components. CA-125 level was 55 kU/L, and Risk of Malignancy Index-2 score was 880...

Struma ovarii is a rare tumor, which accounts for 2.7% of ovarian teratomas and 0.01% of ovarian tumors. It usually affects women in the fifth decades of life and is most often detected incidentally during ultrasound and then confirmed histologically. The gold standard treatment is surgery and prognosis is excellent. We here report the particular case of a young female patient with giant struma ovarii whose radiological features were classified as unusual presentation. We match patient's data with those from the literature...

BACKGROUND: Mesenteric cyst is a rare clinical entity especially in pregnancy; therefore, few cases have been reported in the literature. The standard method of their treatment is surgical excision either with laparotomy or laparoscopy. In addition, mesenteric vein thrombosis is a rare and life-threatening condition in pregnancy and needs immediate treatment because it can lead to intestinal necrotic ischemia. This is the first report of the coexistence of mesenteric cysts and mesenteric vein thrombosis during gestation...

Ovaries of Acipenser baerii are of an alimentary type and probably are meroistic. They contain ovarian nests, individual follicles, inner germinal ovarian epithelium, and fat tissue. Nests comprise cystoblasts, germline cysts, numerous early previtellogenic oocytes, and somatic cells. Cysts are composed of cystocytes, which are connected by intercellular bridges and are in the pachytene stage of the first meiotic prophase. They contain bivalents, finely granular, medium electron dense material, and nucleoli in the nucleoplasm...

High-grade serous ovarian cancer (HGSOC) is characterized by a TP53 mutation rate of up to 96.7% and associated with a more aggressive tumor biology. The origin of HGSOC is thought to arise either from fallopian tube secretory cells or the ovarian surface epithelium/inclusion cysts, the former with more evidence. Peritoneal tumor spread is heterogeneous, either excessive in the peritoneum (with miliary appearance) or more confined to the ovaries with only few (bigger and exophytically growing) peritoneal implants...

PURPOSE: Gonadotroph adenomas are pituitary adenomas with inefficient and variable secretory characteristics, that is why they are usually considered as a subgroup of nonfunctioning pituitary adenomas (NFPA) and are recognized only at immunohistochemistry. When gonadotroph adenomas secrete active hormones, they may cause spontaneous ovarian hyperstimulation syndrome (OHSS) in premenopausal women. Aim of our study is to describe three women with OHSS diagnosed before the removal of the adenoma and to calculate the prevalence of OHSS in premenopausal women with a clinical diagnosis of NFPA...

Polycystic ovarian syndrome (PCOS) is an endocrine-metabolic disorder characterized by hormonal disturbances including hyperandrogenemia, insulin resistance, and hyperinsulinemia culminating into obesity, multiple ovarian cysts and anovulatory infertility in women. There has been no effective medication against PCOS and its complication. However, weight loss can reduce insulin resistance, which in turn helps to restore hormonal balance and ovulation resulting to improved fertility. Previously, we reported that alkaline reduced water (ARW) could significantly reduce obesity by alleviating adiposity, regulating the levels of adipokines/pro-inflammatory cytokines and by inducing cholesterol homeostasis...

Tailgut cysts, also known as retrorectal hamartomas, are very rare neoplasms located in the presacral/retrorectal space that originate from the embryonic hindgut. Although a majority of lesions in this location are benign, 30% of the reported cases in the literature were found to be malignant. This report describes a case of a presacral mass found on CT of a 37-year-old woman who initially presented with worsening abdominal pain and a history of ovarian cyst rupture. This patient's clinical picture was complicated by an enlarging ovarian cyst...

Recent studies suggest that long non-coding RNAs (lncRNAs) play crucial roles in many types of human malignant cancers. However, the function of lncRNAs in benign tumors remains poorly understood. In the present study, to explored the potential roles of lncRNAs in benign epithelial ovarian cysts (BEOCs) which commonly occur in young women and possess malignant potential, we described the expression profile of the lncRNAs between BEOC and normal ovarian tissues using lncRNA microarray techniques. The results showed that 1,325 transcripts of lncRNAs (1,014 upregulated and 311 downregulated) were differentially expressed in the BEOCs compared with the normal controls [absolute fold-change ≥2, false discovery rate (FDR) <0...

OBJECTIVE: The reasons why endometriosis is more aggressive and invasive in some patients are unknown. Despite the importance of population-based clinically defined risk factors in the prediction of recurrence, biochemical markers obtained from the patient are more valuable for prediction on an individual basis. Therefore, the discovery of significant potential biomarkers could be useful to clinicians for shedding light on the pathogenesis of endometriosis and in the monitoring recurrence...

Tankyrases are physiological regulators of Axin, a protein involved in several cellular processes, including Wnt signaling. Here, we investigated the effect of a specific Tankyrase inhibitor (XAV939) in follicular-luteal dynamics, and its possible relationship with ovarian vascular development. Studies were designed to analyze the effect of intrabursa administration of XAV939 in gonadotropin-treated prepubertal rats. In particular, we examined follicle and corpus luteum development, steroidogenesis, angiogenic markers, and apoptotic parameters...

Sidika E Karakas
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder affecting young women. Even though the definition of PCOS has changed over the years, all diagnostic criteria include two or more of the following: oligomenorrhea/oligoovulation/anovulation, androgen excess and polycystic ovaries (PCO). Traditional method of assessing the ovarian morphology has been transvaginal pelvic ultrasound. Recent studies support that serum anti-Mullerian hormone (AMH) levels correlate with the number of ovarian follicles and cysts...

BACKGROUND: Ovarian cancer is the leading cause of death among gynecologic diseases in Western countries. We have previously identified a miR-200-E-cadherin axis that plays an important role in ovarian inclusion cyst formation and tumor invasion. The purpose of this study was to determine if the miR-200 pathway is involved in the early stages of ovarian cancer pathogenesis by studying the expression levels of the pathway components in a panel of clinical ovarian tissues, and fallopian tube tissues harboring serous tubal intraepithelial carcinomas (STICs), a suggested precursor lesion for high-grade serous tumors...

Cancer cells employ many strategies to evade immune defense and to facilitate tumor growth and angiogenesis. As a novel mode of intercellular communication, cancer-derived exosomes contribute to the recruitment and mediation of lymphocytes within the tumor environment. However, the mechanisms and key molecules mediating the effect of exosomes on lymphocytes are unclear. We treated healthy peripheral blood lymphocytes with exosomes from ovarian cancer and ovarian cysts and screened for differentially expressed genes using the RT(2) Profiler Cancer Inflammation and Immunity Crosstalk PCR Array...
