INTRODUCTION: Ovarian teratomas undergo the malignant transformation in 0.2-2% of cases. The behavior of malignancies in mature cystic teratomas (MCT) is determined by their phenotype and not their derivation from germ cells. We can recognize pure angiosarcomas or as a part of other tumors like malignant mixed Mullerian tumors and adenosarcomas. PRESENTATION OF CASE: We present the first case of bilateral ovarian angiosarcoma arising from the mature teratomas. Due to widespread disease, we performed limited surgical procedure consisting of bilateral adnexectomy and omentectomy...

The article discusses the features of epidemiology, morphology, clinical course and modern principles of diagnostics and treatment of tumors of female genitals of children and adolescents. Special attention is paid to ovarian germ cell tumors. The use of immunohistochemical and tumor markers enables the differential diagnosis among malignant ovarian germ cell tumors. Nowadays surgical methods, chemotherapy and radiation therapy are applied in treatment of tumors of female genitals. The main standard of surgical operation of ovarian tumors is removal of appendages on the side of the affection...

Yolk sac tumor (YST) is the second most common subtype of ovarian germ cell tumors. It usually occurs in the second and third decades of life and is rare in postmenopausal women. In postmenopausal women, YST is commonly an aggressive tumor and can present as a pure germ cell component or as a mixed component with other germ cell or epithelial components. The recognition of this histological subtype is important not only for differential diagnosis but also for determining prognosis and treatment decisions. In this case report, we describe a 61-year-old woman with YST coexisting with epithelial carcinoma focusing on the efficacy of systemic therapies...

Malignant Germ Cell Tumors have primarily affecting adolescents and young adults. In advanced disease, greater than 70% of patients can be cured with standard chemotherapy regimens and fertility-sparing surgery appears to be safe with excellent survival after long-term follow-up. Due to their rarity, follow up and fertility management is largely based on trials of epithelial ovarian cancer or on few small studies. We report a review of the literature studies about the assessment, the monitoring and the treatment of fertility for Malignant Germ Cell Tumors as pratical guidelines for management of fertility in these patients...

Collision tumors are uncommon neoplasms in which elements of differing histologic origins coexist in a single mass. Ovarian collision tumors are a rare subtype of such lesions. The identification of collision tumors by radiologic examinations is essential to ensure that comprehensive biopsies are performed to guide appropriate treatments. According to the clinical and imaging findings of 12 patients and reviews of previous studies, ovarian collision tumors are mixtures of different combinations of epithelial tumors, germ cell tumors, and sex-cord-stromal tumors...

BACKGROUND: Whereas among pediatric oncologists, ovarian yolk sac tumor (O-YST) is considered a chemosensitive tumor, it is often cited as an adverse prognostic factor in adult women with ovarian germ cell tumors. METHODS: The Malignant Germ Cell International Consortium data set included 6 pediatric clinical trials (United States, United Kingdom, and France) and 2 adult gynecology clinical trials (United States). Any patient with an O-YST that was International Federation of Gynecology and Obstetrics stage IC or higher and treated with a platinum-based chemotherapy was eligible...

Ovarian teratomas are tumors resulting from pluripotent germ cells. We here describe 3 different types of teratomas: mature, immature and monodermal teratomas. Immature teratoma accounts for less than 1% of ovarian cancers and mainly affects young subjects. We report the case of a 25 year female patient, admitted with abdomino pelvic mass. She underwent ultrasound and a pelvic CT scan followed by conservative treatment based on left annexectomy associated with multiple biopsies. Anatomopathological examination showed immature ovarian teratoma...

Gonadoblastoma is an uncommon ovarian tumor arising primarily in females with gonadal dysgenesis and a 46, XY karyotype. Germ cell tumors arising within and/or overgrowing a gonadoblastoma have been reported. We report a rare case of a malignant mixed germ cell tumor (yolk sac tumor and choriocarcinoma) arising in a gonadoblastoma of the left ovary in a 19-year-old female with a 46, XX karyotype. The patient's initial α-fetoprotein level was 20 000 KIU/L. The patient underwent a laparoscopic unilateral salpingo-oophorectomy with omentectomy and peritoneal washing followed by adjuvant chemotherapy...

Infertility is a global health problem with an estimated incidence of 15%. Exposure to chemicals is a potential causal factor, and there is a lack of studies examining the effects on female germ cells. Here, we have studied the impact of different aryl hydrocarbon receptor (AHR) modulators on human ovarian follicles using a human ovarian tissue culture model. Expression of AHR was analyzed in tissue samples, and effects of the selected ligands resveratrol (RSVL), 6-formylindolo(3,2-b)carbazole (FICZ), and alpha-naphthoflavone (aNF) on AHR transactivation studied in a granulosa cell tumor line...

Ovarian germ cell tumors (OGCTs) and sex cord stromal tumors (SCSTs) are rare gynecologic tumors that are derived from germ and stromal cells, respectively. Unlike their epithelial counterparts, molecular pathogenesis of these tumor types is still poorly understood. Here, we characterized microRNA (miRNA) expression profiles of 9 OGCTs (2 malignant and 7 benign) and 3 SCSTs using small RNA sequencing. We observed significant miRNA expression variations among the three tumor groups. To further demonstrate the biological relevance of our findings, we selected 12 miRNAs for validation in an extended cohort of 16 OGCTs (9 benign and 7 malignant) and 7 SCSTs by reverse transcription-quantitative polymerase chain reaction...

The incidence of ovarian cancer depends on the ethnicity and geographical area. Menopausal status is a well-known risk factor for ovarian cancer and most cases occur after menopause in Caucasians. However, it is less clear how the status of menopause or age at diagnosis is associated with ovarian cancer including its subtypes in Chinese women. Data on 1,283 women with primary malignant or borderline ovarian cancer including age at diagnosis, age at menopause and histology from the largest women's hospital in China was analysed...

BACKGROUND: Malignant ovarian germ cell tumors (MOGCTs) are a rare form of ovarian malignancy. Socioeconomic status (SES) has been shown to affect survival in several gynecologic cancers. We examined whether SES impacted survival in adolescent and young adults (AYAs) with MOGCT. MATERIALS AND METHODS: The National Cancer Data Base was used to identify AYAs (aged 15-39 years) with MOGCT from 1998 to 2012. Three SES surrogate variables identified were as follows: insurance type, income quartile, and education quartile...

Ovarian germ cell tumors (GCTs) are rare and affect mainly young girls and women. Two histological groups are distinguished: dysgerminomas and nondysgerminomatous tumors. These tumors have initial good responses to surgery and chemotherapy in 80% cases, but >75% of patients die due to complications of disease progression. There are very few case reports of mixed GCT with extradural spine metastases. We report a rare case of a 17-year-old girl who had undergone left salpingo-oophorectomy with omental and peritoneal biopsy for ovarian GCT with extradural spinal metastasis...
