Ovarian dermoid cyst is a benign germ cell tumor usually occurring during fertile age. In contrast, giant omental dermoid is extremely rare and is thought to originate from ovarian torsion, detachment and omental implantation. We present a case of a 73 year old patient with 26 cm giant omental dermoid weighing more than 6 kg. During surgery, aspiration of the cystic part facilitated the delivery of the big mass through a relative small abdominal incision.

Wilms tumor 1 (Wt1) is an essential factor for urogenital system development. Teleosts have two wt1s, named as wt1a and wt1b. In this study, the expression pattern of wt1a and wt1b and their functions on the urogenital system were analyzed by in situ hybridization and CRISPR/Cas9. wt1a was found to be expressed in the glomerulus at 3 dah (days after hatching), earlier than wt1b. wt1a and wt1b were simultaneously expressed in the somatic cells of gonads at 3 dah, while their cell locations were similar, but not identical in adult fish gonads...

Background: High-dose chemotherapy (HDC) with hematopoietic progenitor cell transplantation is a standard option for relapsed/refractory testicular germ cell tumor (GCT), but only few data have been reported in female patients with GCT. We conducted a retrospective analysis of female patients with GCT treated with HDC and registered with the European Society for Blood and Marrow Transplantation (EBMT). Patients and methods: Between 1985 and 2013, 60 registered female patients with GCT, median age 27 years (range 15-48), were treated with salvage HDC...

PURPOSE OF REVIEW: Three primary categories of gynecologic cancer are found in pediatric and adolescent patients: stromal carcinomas including juvenile granulosa cell tumors and Sertoli-Leydig cell tumors, rhabdomyosarcomas arising from the vagina and cervix (sarcoma botryoides), and ovarian germ cell tumors which comprise a wide range of histologies. These entities are rare and treatment approaches have focused on decreasing late effects of chemotherapy treatment. Here, we review presentation, histologic classifications, diagnosis, and treatment recommendations for pediatric gynecologic cancers...

INTRODUCTION: Germ cell tumors account for 20-25% of ovarian neoplasms. Mature cystic teratoma (MCT) is the most common ovarian germ cell tumor. Malignancy in MCT is seen in 1-2% of the cases. Squamous cell carcinoma (SCC) accounts for 80% of the cases and carries a poor prognosis. AIM: To study the clinicopathological factors, management protocols and its outcome. MATERIALS AND METHODS: Case records reviewed from August 2006 to August 2011 at our institute identified 10 women with SCC in ovarian MCT...

Sex cord-stromal tumors (SCSTs) are the second most frequent category of testicular neoplasms, accounting for approximately 2-5% of cases. Both genetic and epigenetic factors account for the differences in frequency and histologic composition between testicular and ovarian SCSTs. For example, large cell calcifying Sertoli cell tumor and intratubular large cell hyalinizing Sertoli cell neoplasia occur in the testis but have not been described in the ovary. In this article, we discuss recently described diagnostic entities as well as inconsistencies in nomenclature used in the recent World Health Organization classifications of SCSTs in the testis and ovary...

OBJECTIVE: The last large study of second primary tumors (SPTs) in women with ovarian cancer was published in 1996, prior to major changes in the differential diagnosis and treatment. The present study reports on the incidence of SPTs in a contemporary cohort of patients with a diagnosis of ovarian cancer. METHODS: Ovarian cancer patients with a diagnosis of an ovarian malignancy between 1992 and 2012 were identified and characterized from 13 registries of the Surveillance, Epidemiology, and End Results database...

Our recent perplexing findings that polyploid giant cancer cells (PGCCs) acquired embryonic-like stemness and were capable of tumor initiation raised two important unanswered questions: how do PGCCs acquire such stemness, and to which stage of normal development do PGCCs correspond. Intriguingly, formation of giant cells due to failed mitosis/cytokinesis is common in the blastomere stage of the preimplantation embryo. However, the relationship between PGCCs and giant blastomeres has never been studied. Here, we tracked the fate of single PGCCs following paclitaxel-induced mitotic failure...

Two testicular mixed germ cell tumors, from men of 21 and 41 years, in which polyembryoma predominated are described. A literature review uncovered an additional five testicular and nine ovarian cases. One tumor occurred in a 60-year-old man, but all others occurred within the typical age range of gonadal germ cell tumors. One male presented with gynecomastia and one female with sexual precocity, but all otherwise had standard clinical manifestations. These tumors are typically large with non-specific gross features, but a few have a prominent hemorrhagic appearance...

Teratomas are tumors derived from germ cells, most frequently arising in the gonads. The aim of this study was to determine the number of ovarian teratomas diagnosed in the routine biopsy material at Ljudevit Jurak Clinical Department of Pathology, Sestre milosrdnice University Hospital Center during a 5-year period, as well as their clinical, gross and microscopic characteristics. Teratomas accounted for 48.6% (n=166) of primary ovarian tumors. The patient mean age was 34.74±12.37 years. Difference in the incidence of teratoma between the left and right ovary was not significant; bilateral teratoma was found in 13 patients...

Ovarian carcinomas (OC) often demonstrate rapid tumor shrinkage upon neoadjuvant chemotherapy (NACT). However, complete pathologic responses are very rare and the mechanisms underlying the emergence of residual tumor disease remain elusive. We hypothesized that the change of somatic BRCA1 status may contribute to this process. The loss-of-heterozygosity (LOH) at the BRCA1 locus was determined for 23 paired tumor samples obtained from BRCA1 germ-line mutation carriers before and after NACT. We observed a somatic loss of the wild-type BRCA1 allele in 74% (17/23) of OCs before NACT...

Importance: Cancer occurs in 0.05% to 0.1% of all pregnancies. Despite literature reporting good oncologic and fetal outcomes in women treated for cancer during pregnancy, as many as 44% of gynecologists would offer termination, and 37% would not administer chemotherapy or radiotherapy in pregnancy. Objectives: The aims of this study were to summarize current recommendations for the treatment of cervical and ovarian cancers in pregnancy and to review updates on existing knowledge regarding the safety of surgical and chemotherapeutic treatments in pregnancy, including both oncologic and fetal outcomes...

A standard regimen for ovarian malignant germ cell tumors is bleomycin, etoposide, cisplatin(BEP)chemotherapy. Adherence to a treatment schedule of every 21 days has been reported to be important. However, the incidence of febrile neutropenia( FN)and the optimaluse of granulocyte-colony stimulating factor(G-CSF)are unclear because of the low incidence of ovarian malignant germ cell tumors. We experienced 2 cases of ovarian malignant germ cell tumors that received BEP therapy after fertility-conserving surgery...

OBJECTIVE: Alpha-inhibin and calretinin have been traditionally used as immunomarkers for sex cord stromal tumors. However, the variation in their immunoreactivity and their lack of specificity for sex cord stromal tumor makes the search for a more sensitive and specific immunohistochemical marker essential in routine diagnosis of sex cord stromal tumor. This study was conducted to correlate the diagnostic utility of FOXL2 with inhibin and calretinin in the diagnosis of sex cord stromal tumors of ovary...

Yolk sac tumor of the ovary is a rare but highly malignant and aggressive germ cell tumor. The objective of this case study of an ovarian yolk sac tumor was to identify putative pathways that are known to pose a block in differentiation, both in early embryogenesis and in tumorigenesis, that might be amenable to low toxicity therapies designed to promote differentiation to a more benign state and prevent recurrent disease in such tumors. The enhancer of Zeste homolog 2 (EZH2), a histone methyl transferase, and silent mating type information regulation 2 homolog 1 (SIRT1), a NAD+ histone deacetylase, are two such pathways...
