INTRODUCTION: Persistent Müllerian Duct Syndrome (PMDS) is a rare sexual disease. It is characterized by the presence of female reproductive structures such as uterus, cervix, fallopian tubes and upper part of vagina in a normal genotypically and phenotypically male. The diagnosis is usually incidental since the patients will present with normal external genitalia and secondary sexual characteristics. Imaging techniques such as magnetic resonance imaging (MRI), computed tomography (CT) scan, or ultrasound (US) could help in the diagnosis...

We report the imaging findings of three ovarian dysgerminomas that coexisted with other germ cell tumors or gonadoblastomas, focusing on the distribution of tumor nests and vascular architecture, which might provide information about the pathogenesis of dysgerminomas. In a 14-year-old female with dysgerminoma and coexisting gonadoblastomas, contrast-enhanced magnetic resonance imaging (MRI) demonstrated a solid mass in the right ovary, which presented as hyperintense lobules on diffusion-weighted imaging separated by fibrovascular septa...

Liver hemangiomas are the most common benign primary tumors of the liver. Due to their high prevalence, incidental finding of hemangiomas during radiological workup of oncologic patients is not uncommon. We present the case of a patient diagnosed of an ovarian immature teratoma and hepatic lesions with typical radiological appearance of hemangiomas that decreased in size during adjuvant chemotherapy with BEP regimen (cisplatin, etoposide and bleomycin). Chemotherapy-induced shrinkage of hepatic hemangiomas can mimic the response of liver metastases to chemotherapy and may induce erroneous interpretations...

Ovarian malignancies are rare in pregnancy; however, the incidence of abnormal adnexal masses diagnosed during pregnancy is increasing. The most common masses are ovarian cysts, and only 3-6% of those are malignant. The majority of ovarian masses are diagnosed at an early stage by routine ultrasound examinations. Malignant germ cell tumors are the most common ovarian malignancies associated with pregnancy, while the incidence of epithelial ovarian cancer is only 1:12,000-1:50,000 of pregnancies. The diagnosis and management of ovarian cancer during pregnancy remain unclear due to the rare occurrence and scant data on this condition...

INTRODUCTION: Rare ovarian tumors include complex borderline ovarian tumors, sex-cord tumors, germ cell tumors, and rare epithelial tumors. Indications and modalities of fertility preservation, infertility management and contraindications for hormonal contraception or menopause hormone therapy are frequent issues in clinical practice. A panel of experts from the French national network dedicated to rare gynaecological cancers, and of experts in reproductive medicine and gynaecology have worked on guidelines about fertility preservation, contraception and menopause hormone therapy in women treated for ovarian rare tumors...

PURPOSE: In this report, we characterize the timing and behavior of malignant ovarian germ cell tumors (GCTs) in pediatric patients with dysgenetic gonads compared to those with normal gonadal development. PATIENTS AND METHODS: Patients from the Children's Oncology Group AGCT0132 with malignant ovarian GCTs were included. Within this population, we sought to identify patients with gonadoblastoma, streak ovaries, or other evidence of gonadal dysgenesis (GD). Patients with malignant GCTs containing one or more of the following histologies-yolk sac tumor, embryonal carcinoma, or choriocarcinoma-were included...

BACKGROUND: Malignant ovarian germ cell tumor is a rare type of disease, which generally has a good prognosis due to the high chemosensitivity of this type of tumor. Fertility preservation is an important issue because malignant ovarian germ cell tumor commonly affects young women. Although conservation is the standard for early stage, it becomes more debatable as the disease progresses to more advanced stages. AIM: Report the case of a patient with an International Federation of Gynecology and Obstetrics Stage IIIc malignant ovarian germ cell tumor, who had conservative surgery and chemotherapy with a good fertility outcome...

We report on the case of a 12-year-old girl, who presented with an ovarian germ cell tumor and cytopenia (anemia and thrombocytopenia) as an associated paraneoplastic syndrome, which gradually regressed after the tumor's removal. This report adds to the previously described paraneoplastic syndromes potentially associated with ovarian germ cell tumor.

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...
