Abstract
Introduction. Tumors and tumor-like lesions of the uterine adnexa in children and adolescents are uncommon but may carry devastating consequences. Methods. We conducted an observational retrospective cohort study, to describe patients aged 0 to 19 years diagnosed with tumors and tumor-like lesions of the uterine adnexa at our institution between 2000 and 2018. Results. Eighty-nine patients with 105 adnexal lesions were included. Thirty-seven (42%) patients presented with benign tumors, 13 (15%) with borderline tumors, 25 (28%) with malignant tumors and 14 (16%) with tumor-like lesions. Germ cell tumors (n = 45|43%) were the most frequent, followed by epithelial tumors (n = 30|29%). No significant differences were found in the age distribution of the lesions by malignant potential or histologic group. Most patients (n = 80|90%) were treated primarily with conservative surgery, including cystectomy (n = 25|28%) and unilateral oophorectomy/adnexectomy (n = 54|61%). Thirty-four (38%) underwent surgical staging (partial omentectomy and peritoneal biopsies). Twenty (23%) patients with borderline and malignant tumors were submitted to chemotherapy. Four (5%) patients with borderline or malignant tumors relapsed, one of whom died from disease. Conclusion. Gynecological lesions in children and adolescents encompass a wide range of rare histological tumor subtypes, requiring evaluation by experienced pathologists. Most tumors were diagnosed at early stages, with low relapse and mortality rates. Conservative management, with fertility sparing surgery and limited use of adjuvant chemotherapy, is of utmost importance.

Abstract
We report a case of dysgerminoma in a 22-year-old woman diagnosed with chromosomal abnormality, balanced translocation 46X,t(X:1)(q22;q21). She had received hormone replacement therapy for 7 years for primary amenorrhea. She visited a primary care physician because of lower abdominal distension, and a large tumor in the pelvis was discovered. She was admitted to our hospital for further examination of the pelvic tumor. She underwent laparotomy and was diagnosed with stage IIIA1 dysgerminoma (pT3apN0pM0) of the left ovary. Young female patients without the Y chromosome who are treated for primary amenorrhea may also develop malignant germ cell tumors; therefore, gynecologists should provide hormone replacement therapy and periodic pelvic evaluation.

Abstract
Gonadoblastoma is a neoplasm containing an intimate mixture of germ cells and elements resembling immature granulosa or Sertoli cells. It has been considered as in situ germ cell malignancy that can be associated with malignant components. The tumor has been reported to almost exclusively develop in various types of gonadal gene mutation syndromes, such as in pure or mixed gonadal dysgenesis and among females carrying Y chromosome material. However, it can be rarely present in normal women with 46, XX karyotype. Ovarian gonadoblastoma presenting with signs of contrasexual puberty in a young female child with normal 46, XX karyotype is an extremely rare clinical entity and seldom reported in the literature. We report a case of a nine-year-old girl child who presented with signs of virilization and contrasexual pubertal development. A detailed clinical evaluation along with supportive biochemical and radiological findings pointed to the presence of a virilizing ovarian tumor. The patient underwent right salpingo-oophorectomy, pelvic node dissection, and infracolic omentectomy. The excised tumor was confirmed to be gonadoblastoma which was overgrown by dysgerminoma on histopathological evaluation. The presence of associated malignant tumors (like dysgerminoma) should always be ruled out in cases of gonadoblastoma.

Abstract
Dissecting gonadoblastoma (DGB) of the ovary, a recently described terminology, defines a unique distribution of neoplastic germ cells. Here, we report a case of incidental DGB coexistent with an atypical endometriotic cyst occurring in a 23-year-old woman. The ovarian cyst was lined by endometrial-like glands and stroma. Some glands displayed nuclear enlargement and hyperchromasia, and abundant eosinophilic cytoplasm with occasional intracytoplasmic hemosiderin and mucin vacuoles. The neoplastic germ cells resembled those of ovarian dysgerminoma and were diffusely distributed within the ovarian stroma, which was stretched around the wall of the endometriotic cyst. These cells were arranged in nests and cords, possessing clear cytoplasm and centrally located round nuclei with prominent nucleoli and occasional mitoses. Chromosomal analysis revealed a 46,XX karyotype. We describe the clinical, histological, immunophenotypical, and genetic features of ovarian DGB incidentally detected in the ovarian cystectomy specimen of a woman with normal female karyotype.

Abstract
17α-hydroxylase/17,20-lyase deficiency (17-OHD), caused by mutations in the gene of the cytochrome P450 family 17 subfamily A member 1 (CYP17A1), is a rare type of congenital adrenal hyperplasia (CAH), usually characterized by cortisol and sex steroid deficiency combined with excessive mineralocorticoid. Gonadoblastoma is a relatively rare ovarian tumor that is frequently seen among patients with 46,XY gonadal dysgenesis. Rarely have they been reported in female patients with normal 46,XX karyotype. Here, we report an interesting case of an 11-year-old Chinese girl who presented acute abdominal pain that was later attributed to tumor rupture of right ovarian gonadoblastoma with dysgerminoma. Further evaluations revealed hypertension and hypokalemia. Hormonal findings showed increased progesterone, hypergonadotropic hypogonadism, and low cortisol levels. Her chromosome karyotype was 46,XX without Y chromosome material detected. Genetic analysis revealed that the patient had a homozygous pathogenic variant c.985_987delTACinsAA (p.Y329Kfs*90) in exon 6 of the CYP17A1 gene and that her parents were all heterozygous carriers of this pathogenic variant. Due to the variable clinical manifestations of 17-OHD, meticulous assessment including genetic analysis is necessary. Further study is warranted to unravel the mechanism of gonadoblastoma in a patient with normal karyotypes.

Abstract
Gonadoblastoma is a rare ovarian neoplasm which belongs to “germ cell-sex cord-stromal tumor” category. This tumor is frequently associated with invasive germ cell malignancy. It commonly arises in dysgenetic gonads of young individuals who are phenotypically females but possess 46XY karyotype. It has been rarely reported in females with normal phenotype and genotype. We herein describe a case of 10-year-old female who presented with abdominal pain, abdominal distention and fever. CT scan of the abdomen and pelvis revealed bilateral ovarian masses, ascites and pelvic and para-aortic lymphadenopathy. Serum lactate dehydrogenase levels were also elevated. She underwent left salpingo-oophorectomy, right ovarian biopsy, omentectomy and para-aortic lymphadenopathy. Microscopically, tumor showed in situ and invasive components. In situ component was arranged in nests and lobules formed by immature sertoli cells forming acini and encircling large polygonal primitive germ cells. Immature sertoli cells were positive for immunohitochemical (IHC) stains cytokeratin AE1/AE3, inhibin and calretinin, while germ cells were positive for SALL4, Oct 3/4, placental alkaline phosphatase (PLAP) and CD117. Invasive component was arranged in sheets of large-sized, polygonal-shaped primitive germ cells which were also positive for SALL4, Oct 3/4, PLAP and CD117 IHC stains. Hence, the diagnosis of “gonadoblastoma with dysgerminoma” was made. The tumor was limited to both ovaries. Cytogenetic analysis of peripheral blood revealed normal female 46XX karyotype. The patient received two cycles of adjuvant chemotherapy and was then lost to follow-up. We conclude that gonadoblastoma, although rare, should be considered as a differential diagnosis in ovarian tumors of young females. Invasive germ cell component should always be carefully searched for as it guides about treatment and predicts prognosis.

Abstract
BACKGROUND Gonadoblastoma (GB) is a rare mixed germ cell-sex cord-stromal tumour, first described in humans, commonly found in dysgenetic gonads of intersex patients that have a Y chromosome. However, this entity in not recognized in the WHO classification of tumours of genital system of domestic animals. Herein, we describe a case of ovarian gonadoblastoma with proliferation of dysgerminoma and sex cord-stromal tumour components, in a phenotypically and cytogenetically normal bitch. CASE PRESENTATION A 17-year-old cross-breed bitch had a firm, grey-white multinodular mass in the left ovary. The tumour was submitted to histopathological examination and Y chromosome detected through karyotype analysis and PCR studies. Microscopically, the ovary was almost replaced by an irregular neoplasm composed of three distinct, intermixed elements: dysgerminoma, mixed germ cell-sex cord-stromal tumour resembling human GB and a proliferative sex cord-stromal tumour component. The germ cells of gonadoblastoma and dysgerminoma components were immunoreactive for c-KIT. Sex cord-stromal cells of gonadoblastoma were immunoreactive for α-inhibin. The sex cord-stromal tumour was immunoreactive for AE1/AE3, occasionally for α-inhibin and negative for epithelial membrane antigen (EMA). The karyotype was 78, XX and PCR analysis confirmed the absence of the Y chromosome. CONCLUSION Based on these findings, a diagnosis of gonadoblastoma with proliferation of dysgerminoma and sex cord-stromal tumour was made. This is the first case of ovarian gonadoblastoma in a female dog.

Abstract
This review describes the germ cell neoplasms that are malignant and most commonly associated with several types of gonadal dysgenesis. The most common neoplasm is gonadoblastoma, while others including dysgerminomas, yolk-sac tumors and teratomas are rare but can occur. The purpose of this review is to evaluate the incidences of these abnormalities and the circumstances surrounding these specific tumors.According to well-established methods, a PubMed systematic review was performed, to obtain relevant studies published in English and select those with the highest-quality data.Initially, the first search was performed using gonadal dysgenesis as the search term, resulting in 12,887 PubMed papers, published, from 1945 to 2017. A second search using ovarian germ cell tumors as the search term resulted in 10,473 papers, published from 1960 to 2017. Another search was performed in Medline, using germ cell neoplasia as the search term, and this search resulted in 7,560 papers that were published between 2003 to 2016, with 245 new papers assessing gonadoblastomas.The higher incidence of germ cell tumors in gonadal dysgenesis is associated with a chromosomal anomaly that leads to the absence of germ cells in these gonads and, consequently, a higher incidence of neoplasms when these tumors are located inside the abdomen. Several hypotheses suggest that increased incidence of germ cell tumors involves all or part of the Y chromosome or different genes.

Abstract
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. Some small nodules were found to exist separately from the lobules (multiplicity) and to include pathological remnants of gonadoblastoma. Large tumor vessels were present at the center of the mass (central blood vessels), which were in direct contact with the ovarian veins and radiated peripherally through the fibrovascular septa. In a 35-year-old female, a mixed germ cell tumor, which was mainly composed of dysgerminoma and yolk sac tumor foci, exhibited the same vascular architecture pattern as the first dysgerminoma on contrast-enhanced computed tomography. In a 10-year-old female with a mixed germ cell tumor, contrast-enhanced MRI revealed an enlarged left ovary, which contained a large heterogeneous mass and multiple tiny nodules (multiplicity). Microscopically, the former corresponded to a yolk sac tumor, and the latter corresponded to a dysgerminoma containing remnants of gonadoblastoma. Based on these cases, the presence of tumor nest multiplicity and central blood vessels might aid the diagnosis of dysgerminoma, and these imaging findings might be indicative of the synchronous development of multiple dysgerminomas from primordial germ cells or gonadoblastomas.

Abstract
We report a unique case of gonadal mixed germ cell tumor (GCT) composed of a predominantly spermatocytic tumor (ST)-like component and a minor component of germinoma arising in gonadoblastoma in a phenotypic woman with a 46, XX peripheral karotype. The patient was a 24-year-old woman (gravida 2, para 1) found to have a 7 cm pelvic mass during routine obstetric ultrasound examination at 20 weeks gestational age. She underwent a left salpingo-gonadectomy at gestational age 23 and 2/7 weeks. She recovered well and delivered a healthy baby at full term. The resected gonadal tumor measured 7.5 cm and microscopically was composed of 3 morphologically distinct components: gonadoblastoma (1%), germinoma (1%) and a ST-like component (98%). The ST-like component was composed of 3 populations of tumor cells: small cells, intermediate and large sized cells, similar to testicular ST. Scattered binucleated and multinucleated cells were present. Immunohistochemically the ST-like component was positive for pan-GCT markers SALL4 and LIN28 but with weaker staining than the germinoma. It was negative for OCT4 and TCL1. Only rare tumor cells were positive for SOX17. In contrast, the germinoma cells were diffusely and strongly positive for SALL4, LIN28, OCT4, SOX17, and TCL1. CD117 was positive in both the germinoma and ST-like component but with fewer tumor cells positive in the latter. Flurorescence in situ hybridization study demonstrated isochromosome 12p in the germinoma component but not in the gonadoblastoma and ST-like component. This patient did not receive further chemoradiation therapy after the surgery. She has been free of disease for 10 years and 1 month since her surgery. To our knowledge, this is the first case report of a ST-like GCT in a phenotypic female.

Abstract
Gonadoblastoma is a rare gonadal tumour consisting of a mixture of germ cells and sex cord stromal derivatives resembling immature granulosa and Sertoli cells. It usually arises in various types of gonadal dysgenesis containing Y chromosome like pure or mixed gonadal dysgenesis. Occurrence in phenotypically and chromosomally normal women is very rare. We report here a case of gonadoblastoma with dysgerminoma in a 14-years-old girl who presented with a huge tumour, virilisation and normal 46XX karyotype. Association of dysgerminoma is seen in 50% cases of gonadoblastomas. Elevated tumour markers like hCG and alpha Fetoprotein may make the diagnosis challenging.
