Abstract
Objective: To evaluate the incidence, treatment, and survival outcomes of Swyer syndrome with gonadal non-dysgerminoma malignant germ cell tumor (MGCT-NDG). Methods: A retrospective study was performed on Swyer syndrome patients with MGCT-NDG between January 2011 and December 2022 in Peking Union Medical College Hospital to investigate their characteristics and outcomes. Results: A total of 15 patients (4.9%, 15/307) with Swyer syndrome were identified in 307 MGCT-NDG patients. The average age at diagnosis of MGCT-NDG and Swyer syndrome were (16.8±6.7) and (16.7±6.6) years, respectively. Six cases were preoperatively diagnosed as Swyer syndrome, of which 4 cases received bilateral gonadectomy with or without hysterectomy, while the other 2 cases underwent removal of gonadal tumor and unilateral gonadectomy with hysterectomy, respectively. Of the 9 patients postoperatively diagnosed as Swyer syndrome, unilateral gonadectomy, removal of gonadal tumor, and unilateral gonadectomy with hysterectomy were performed in 6 patients, 2 patients, and 1 patient, respectively. Mixed malignant germ cell tumor (MGCT;10 cases), yolk sac tumor (4 cases), and immature teratoma (1 case) were the pathological subtypes, in the descending order. There were International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ in 6 cases, stage Ⅱ in 3 cases, stage Ⅲ in 5 cases, and stage Ⅳ in 1 case, respectively. Eleven patients received reoperation for residual gonadectomy after a average delay of (7.9±6.2) months, including 8 MGCT-NDG patients and 1 gonadoblastoma patient, no tumor involved was seen in the remaining gonads in the other 2 cases. Ten patients experienced at least one recurrence, with a median event free survival of 9 months (5, 30 months), of which 2 patients received surgery only at the time of initial treatment. All patients with recurrence received surgery and combined with postoperative chemotherapy. After a median follow-up of 25 months (15, 42 months), 10 patients were disease-free, 3 patients died of the tumor, 1 died of side effects of leukemia chemotherapy, and 1 survived with disease. Conclusion: The incidence rate of Swyer syndrome in patients with MGCT-NDG is about 4.9%; timely diagnosis and bilateral gonadectomy should be emphasized to reduce the risk of reoperation and second carcinogenesis in this population.

Abstract
Germ cell tumors (GCTs) are associated with pure gonadal dysgenesis or Swyer syndrome. Swyer syndrome usually presents with primary amenorrhea, streak ovaries, and mixed GCT. However, our patient presented with secondary amenorrhea, normal female external genitalia, and a mixed GCT. Constitutional karyotype was suggestive of 46,XY. Management comprised chemotherapy, followed by surgery. Histopathology was suggestive of dysgerminoma complicating a gonadoblastoma. The purpose of reporting this case is its rarity and the importance of diagnosing an XY karyotype, as the incidence of GCTs is higher in these patients.

Abstract
INTRODUCTION A gonadectomy is currently recommended in patients with Turner syndrome (TS) and a 45,X/46,XY karyotype, due to a potential risk of gonadoblastoma (GB). However, the quality of evidence behind this recommendation is low. OBJECTIVE This study aimed to evaluate the prevalence of GB, its characteristics, as well as its risk factors, according to the type of Y chromosomal material in the karyotype. METHODS Our study within French rare disease centers included patients with TS and a 45,X/46,XY karyotype, without ambiguity of external genitalia. Clinical characteristics of the patients, their age at gonadectomy, and gonadal histology were recorded. The regions of the Y chromosome, the presence of TSPY regions, and the percentage of 45,X/46,XY mosaicism were evaluated. RESULTS A total of 70 patients were recruited, with a median age of 29.5 years (21.0-36.0) at the end of follow-up. Fifty-eight patients had a gonadectomy, at a mean age of 15 ± 8 years. GB was present in nine cases. Two were malignant, which were discovered at the age of 14 and 32 years, without metastases. Neither the percentage of XY cells within the 45,X/46,XY mosaicism nor the number of TSPY copies was statistically different in patients with or without GB (P = 0.37). However, the entire Y chromosome was frequent in patients with GB (6/9). CONCLUSIONS In our study, including a large number of patients with 45,X/46,XY TS, the prevalence of gonadoblastoma is 12.8%. An entire Y chromosome appears as the main risk factor of GB and should favor early gonadectomy. SIGNIFICANT STATEMENT About 10% of patients with TS have a karyotype containing Y chromosomal material: 45,X/46,XY. Its presence is related to the risk of GB. Therefore, a prophylactic gonadectomy is currently recommended in such patients. However, the quality of evidence is low. Our objective was to evaluate the prevalence of GB according to the type of Y-chromosomal material. We found a prevalence of GB of 12.8% in a cohort of 70 TS patients. No sign of hyperandrogenism was observed. The entire Y chromosome was the most frequent type of Y-material in patients with GB. As the prognosis of these tumors was good, a delay of surgery might be discussed.

Abstract
Frasier syndrome (FS) is a rare condition, caused by splice-site mutations of intron 9 in the Wilms' tumor suppressor gene 1 (WT1 gene). The WT1 protein is essential for urogenital development and patients with 46XY karyotype present with female (FS type 1) or male phenotype, gonadal dysgenesis, progressive glomerulopathy, and high risk of gonadoblastoma. We describe a female patient with an IVS9+4C>T donor splice-site mutation, who underwent a preventive gonadectomy at the age of 6 years due to imaging findings of dysplastic gonads. The biopsy revealed bilateral gonadoblastoma, emphasizing the need for early gonadectomy in 46XY FS patients.

Abstract
BACKGROUND Differences/disorders of sex development (DSD) are congenital conditions in which the development of chromosomal, gonadal, or anatomical sex is atypical. OBJECTIVE The aim of this study is to report the histological characteristics and immunoexpression patterns of gonadal parenchyma in patients with 46,XX testicular and ovotesticular DSD, with a focus on the detection of germ cell malignancies. DESIGN Inclusion criteria were SRY-negative 46,XX testicular and ovotesticular DSD with available samples from gonadal biopsy or gonadectomy for the review of histological findings. Gonadal histology was assessed on hematoxylin and eosin-stained sections and immunohistochemical analysis. Histopathological criteria from the last World Health Organization classification of urogenital tumors were used to identify undifferentiated gonadal tissue, gonadoblastoma, and dysgerminoma. RESULTS Median age at first histological evaluation of gonadal samples was 1.46 years (range: 0.16-16 years). Totally 15 patients were classified as ovotesticular and only 1 as testicular DSD. Most individuals had bilateral ovotestes (12/15). No histological alterations were found in the ovarian parenchyma, while signs of dysgenesis were seen in all cases of testicular parenchyma. In 4/15 ovotesticular DSD, a prepubertal biopsy failed to identify ovarian parenchyma. We detected early prepubertal preinvasive and invasive malignancies in this cohort (five patients had undifferentiated gonadal tissue, five gonadoblastoma, and one dysgerminoma). CONCLUSION 46,XX disorders of gonadal development are historically considered at a low risk for germ cell cancer, and the need for assessment of gonadal histology has been questioned. The finding of early germ cell malignancies in our cohort brings awareness and needs further research.

Abstract
We describe 21 nonpure germinomatous gonadal germ cell tumors (9 with a germinoma component), all but 1 associated with gonadoblastoma, in patients with disorders of sex development who ranged from 7 to 36 years old (average, 20 y). Twenty patients were clinically described as phenotypic females with ambiguous genitalia/virilization and primary amenorrhea. The most common documented peripheral karyotype was 46,XY (10/12; 83%). Fifteen of 16 tumors with available clinicopathologic data were unilateral. They ranged from 7 to 30 cm (mean, 15.5 cm) and were solid and cystic with frequent necrosis and hemorrhage. Gonadoblastoma, in its classic (70%), dissecting (5%), or combined (25%) forms, was identified in all but 1. The malignant germ cell tumors were typically mixed except for 5 pure yolk sac tumors and 1 expansile gonadoblastoma with syncytiotrophoblast cells. When admixed, the most common component was yolk sac tumor (n=10), followed by germinoma (n=9), embryonal carcinoma (n=5), choriocarcinoma (n=4), immature teratoma (n=3), and teratoma (n=2). Typical morphologic patterns of yolk sac neoplasia, including reticular/microcystic, solid (including blastema-like), and endodermal sinus (Schiller-Duval bodies), were seen, as well as glandular (n=10) and hepatoid (n=6) differentiation, with cystically dilated glands and diffuse hepatoid morphology in 3 and 2 tumors, respectively. Two yolk sac tumors showed a sarcomatoid pattern. Somatic-type malignancies (alveolar rhabdomyosarcoma and low-grade spindle cell sarcoma, not otherwise specified) were identified in 1 case each. This is the first large series of germ cell tumors other than typical pure germinoma associated with gonadoblastoma. The high frequency of yolk sac tumor with glandular (especially cystic glandular) and hepatoid morphologies is noteworthy, and their presence should prompt further evaluation for an associated gonadoblastoma and possible disorder of sex development.

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
Gonadoblastoma and mixed germ cell-sex cord stroma tumor have been widely recognized as two separate entities on the basis of both clinical and pathological features. The typical morphological pattern of both tumor types was found by us to coexist in the same gonadal tumor in a 14-year-old 46,XY phenotypically female subject who also had a contralateral dysgerminoma. A subserous implant showing the mixed germ cell-sex cord pattern of the primary tumor was detected in the uterine body. Following therapy the patient is alive and well after a 7-year follow-up. The distinction between gonadoblastoma and mixed germ cell-sex cord stroma tumor requires discussion.

Abstract
We report a case of androgen insensitivity syndrome (AIS) characterized by malignant degeneration of the testes consisting of gonadoblastoma and dysgerminoma. AIS is a rare inherited form of male pseudohermaphroditism that can manifest as a normal female phenotype without müllerian derivatives and absence of the upper third of the vagina. A 32-year-old white 46,XY female with AIS underwent removal of the dysgenetic gonads at the Gynecological Oncology Department of the Istituto Nazionale Tumori, Milan, Italy. We investigated cytogenetic alterations, hormonal levels and the presence of neoplasia in the dysgenetic gonads. Histological analysis revealed a gonadoblastoma mixed with dysgerminoma in the left gonad and a pure dysgerminoma in the right gonad. The patient's hormonal status matched that of a male. Second-look laparotomy after chemotherapy showed a complete pathological response. AIS should be suspected in phenotypically female patients with primary amenorrhea; surgical removal of the gonads is mandatory to avoid malignant degeneration.

Abstract
Gonadal dysgenesis (GD) is a rare congenital malformation that affects about one in 3,000 births. The authors present a case of a 17-year-old woman with primary amenorrhea and poor breast development. They conducted a laparoscopic surgery and bilaterally removed hypoplastic streak gonads. Histopathology of the ovaries revealed bilateral streak gonads with gonadoblastomas and a right-sided dysgerminoma.

Abstract
Patients with Disorders of Sex Development (DSD), especially those with gonadal dysgenesis and hypovirilization are at risk of developing malignant type II germ cell tumors/cancer (GCC) (seminoma/dysgerminoma and nonseminoma), with either carcinoma in situ (CIS) or gonadoblastoma (GB) as precursor lesion. In 10–15% of 46,XY gonadal dysgenesis cases (i.e., Swyer syndrome), SRY mutations, residing in the HMG (High Mobility Group) domain, are found to affect nuclear transport or binding to and bending of DNA. Frasier syndrome (FS) is characterized by gonadal dysgenesis with a high risk for development of GB as well as chronic renal failure in early adulthood, and is known to arise from a splice site mutation in intron 9 of the Wilms’ tumor 1 gene (WT1). Mutations in SRY as well as WT1 can lead to diminished expression and function of SRY, resulting in sub-optimal SOX9 expression, Sertoli cell formation and subsequent lack of proper testicular development. Embryonic germ cells residing in this unfavourable micro-environment have an increased risk for malignant transformation. Here a unique case of a phenotypically normal female (age 22 years) is reported, presenting with primary amenorrhoea, later diagnosed as hypergonadotropic hypogonadism on the basis of 46,XY gonadal dygenesis with a novel missense mutation in SRY. Functional in vitro studies showed no convincing protein malfunctioning. Laparoscopic examination revealed streak ovaries and a normal, but small, uterus. Pathological examination demonstrated bilateral GB and dysgerminoma, confirmed by immunohistochemistry. Occurrence of a delayed progressive kidney failure (focal segmental glomerular sclerosis) triggered analysis of WT1, revealing a pathogenic splice–site mutation in intron 9. Analysis of the SRY gene in an additional five FS cases did not reveal any mutations. The case presented shows the importance of multi-gene based diagnosis of DSD patients, allowing early diagnosis and treatment, thus preventing putative development of an invasive cancer.

Abstract
OBJECTIVE Frasier syndrome (FS) phenotype in 46,XY patients usually consists of female external genitalia, gonadal dysgenesis, high risk of gonadoblastoma and the development of end stage renal failure usually in the second decade of life. FS is caused by heterozygous de novo intronic splice site mutations of the Wilms' tumor suppressor gene 1 (WT1), although a few cases with typical exonic WT1 Denys-Drash mutations that resemble an FS phenotype have been described. The aim of this study was to present further data on the spectrum of FS phenotypes through the evaluation of a 29-year-old patient with a predominantly male phenotype and coexistence of Sertoli cell tumor and gonadoblastoma. RESULTS Genetic analysis using standard methods for DNA sequencing confirmed FS due to a WT1 gene mutation, IVS9+4C>T. CONCLUSIONS This very rare case illustrates the natural course of FS over many years due to the neglect by the patient to address his need for follow-up, while adding further data on the spectrum of FS phenotypes associated with IVS9+4 C>T mutations. The coexistence of the rare Sertoli cell tumor and gonadoblastoma emphasizes that early clinical recognition and molecular identification facilitates appropriate patient management, especially with respect to the high risk of gonadal malignancy.

Abstract
Germ cell tumors are the most frequent ovarian neoplasms among girls and young women under the age of 25. Female patients with gonadal dysgenesis are at higher risk of germ cell tumors. Two cases of women with pure gonadal dysgenesis were described. A hormonally active tumor secreting estrogens, caused the development of sexual features and genital tract bleeding what imitated premature puberty. It needs to be emphasized that the presence of sexual features does not exclude dysgenesis - a pathology that is connected with an increased risk of gonadal tumors--and that the ultrasound evaluation, during which the presence of follicles in gonads is evaluated, is essential.

Abstract
The Foxl-2 gene is involved in eyelid and ovary development. Mutations can lead to a shortened protein and malformations such as BPES associated or not to POF. Forkhead point mutation C134W is a marker of adult type granulosa cell tumors only. Foxl-2 dysregulation is also present in DSD and DSD associated tumors such as Gonadoblastoma and gonadoblastoma like intratubular undetermined germ cell neoplasia. A similar spectrum of pathology involvement is also found for WT1 and RET and gives a new insight into the relationship between development, malformations and oncogenesis.

Abstract
Gonadal dysgenesis is defined by incomplete or defect forming of gonads, a result of disturbed process of migration of germ cells or and their correct organization in gonadal ridge. The combination of dysgenetic gonads and Y chromosome is a prerequisite for developing ovarian neoplasma--most frequent gonadoblastoma. We present a case of mixed gonadal dysgenesis at a patient with caryotype 46XY in combination with gonadoblastoma.

Abstract
Frasier syndrome is an uncommon genetic disorder featuring progressive glomerulopathy, male pseudohermaphroditism, and gonadal dysgenesis with increased risk of gonadoblastoma and malignant germ cell tumors. It is caused by mutations in the donor splice site in intron 9 of the WT1 gene. However, because of its rarity there is limited literature available on the precise spectrum and recommended treatment modalities of this syndrome. We present the clinicopathological findings in 4 patients: 3 phenotypically female adolescents presenting with proteinuria and primary amenorrhea and a 6-month-old baby girl presenting with nephrotic syndrome in whom this very unusual case of early onset was confirmed by molecular studies. The significance of early recognition of Frasier syndrome and its differentiation from Denys-Drash syndrome is reviewed and discussed. Our observation of a case presenting with early clinical manifestations, in contrast with the classical presentation in adolescence, justifies the expansion of the clinical spectrum of Frasier syndrome and contributes to the understanding and appropriate clinical management of these patients.

Abstract
Disorders of sex development (DSD), previously referred to as intersex disorders, comprise a variety of anomalies defined by congenital conditions in which chromosomal, gonadal, or anatomical sex is atypical. Besides issues such as gender assignment, clinical and diagnostic evaluation, surgical and psychosocial management, and sex steroid replacement, the significantly increased risk for developing specific types of malignancies is both clinically and biologically relevant. This relates to germ-cell tumors specifically in DSD patients with hypovirilization or gonadal dysgenesis. The presence of a well-defined part of the Y chromosome (known as the GBY region) is a prerequisite for malignant transformation, for which the testis-specific protein on the Y chromosome (TSPY) is a likely candidate gene. The precursor lesions of these cancers are carcinoma in situ (CIS)/intratubular germ-cell neoplasia unclassified (ITGCNU) in testicular tissue and gonadoblastoma in those without obvious testicular differentiation. Most recently, undifferentiated gonadal tissue (UGT) has been identified as the likely precursor for gonadoblastoma. The availability of markers for the different developmental stages of germ cells allows detailed investigation of the characteristics of normal and (pre)malignant germ cells. Although informative in a diagnostic setting for adult male patients, these markers - such as OCT3/4 - cannot easily distinguish (pre)malignant germ cells from germ cells showing delayed maturation. This latter phenomenon is frequently found in gonads of DSD patients, and may be related to the risk of malignant transformation. Thus, the mere application of these markers might result in over-diagnosis and unnecessary gonadectomy. It is proposed that morphological and histological evaluation of gonadal tissue, in combination with OCT3/4 and TSPY double immunohistochemistry and clinical parameters, is most informative in estimating the risk for germ-cell tumor development in the individual patient, and might in future be used to develop a decision tree for optimal management of patients with DSD.

Abstract
OBJECTIVE Gonadal karyotyping is considered a tool for increasing our knowledge of disturbed gonadal development in patients with gonadal dysgenesis and for estimating more accurately the risk for gonadoblastoma formation. The objective was to gain insight into the role of Y chromosome distribution in the histological heterogeneity of gonads of patients with gonadal dysgenesis. DESIGN Investigation of the possible relationship between peripheral blood karyotype, gonadal karyotype, morphological differentiation patterns of dysgenetic gonads and tumour formation. PATIENTS In total 22 gonadal samples from 19 patients with gonadal dysgenesis (45,X/46,XY and variants n = 14; 46,XY: n = 3; 46,XX: n = 2) were examined. MEASUREMENTS Morphological examination and immunohistochemical staining for testis specific protein, Y encoded (TSPY) and fluorescent and nonfluorescent in situ hybridization directly on gonadal tissue. RESULTS No correlation was observed between peripheral blood karyotype and gonadal karyotype or between gonadal karyotype and the corresponding differentiation pattern. A Y-containing cell line in Sertoli cells was encountered no more frequently than were other cell types. CONCLUSIONS The distribution of the Y-containing cell line in peripheral blood is not a suitable indicator for predicting the histological differentiation pattern found in the gonads of patients with gonadal dysgenesis. The analysis of Y-containing cell lines in the gonads of such patients could be informative with regard to the specific characteristics of gonadal development in humans as compared to chimeric mouse models. Moreover, it is essential to understand the mechanisms underlying disturbed gonadogenesis in these patients. As the gonadal karyotype is not related to the encountered gonadal differentiation pattern, it does not allow prediction of the risk for gonadoblastoma formation.

Abstract
In recent years, our understanding of neoplasms composed of germ cells and sex cord derivatives has increased. In this review, advances in the classification and pathology of ovarian germ cell-sex cord-stromal tumors are discussed. Only 2 neoplasms, each with a distinctive pathogenesis and clinicopathologic features, are included in this category. Gonadoblastoma is a tumor that usually occurs in the dysgenetic gonads of intersex patients that have a Y chromosome, whereas mixed germ cell-sex cord-stromal tumor arises in normal gonads in patients without sex chromosomal abnormalities. Ovarian mixed germ cell-sex cord-stromal tumors differ from their testicular counterparts in their histological appearance, immunohistochemical staining reactions, and biological behavior probably because the latter show a greater degree of maturity of their germ cell component. The introduction of cisplatin-based chemotherapy and the application of tumor markers have dramatically improved the clinical outlook for those patients who develop secondary malignant germ cell neoplasms.

Abstract
BACKGROUND A thorough history, physical examination, and comprehensive work-up is important to differentiate the etiology of a cervical mass in unusual cases. CASE A 36-year-old white female presented with heavy vaginal bleeding, pelvic pain, and an exophytic cervical mass extending to the anterior vaginal wall. She underwent cold knife cone with biopsies of the vagina. Pathology revealed dysgerminoma. Computed tomography of the abdomen and pelvis demonstrated pelvic lymphadenopathy, an enlarged uterus, and a 4 cm complex ovarian mass. The final pathology helped establish the true diagnosis. CONCLUSION The accurate diagnosis of rare tumors requires a broad differential diagnosis and careful review of the pathologic findings and clinical scenario.

Abstract
The testis-specific protein Y-encoded gene (TSPY) is a tandem repeat gene located at the critical region for the gonadoblastoma locus on Y chromosome that predisposes the dysgenetic gonads of intersex individuals to oncogenesis. The expression and molecular properties of TSPY suggest that it is the putative gene for the gonadoblastoma locus on Y chromosome. In this study, we examined the expression of TSPY and other germ cell tumor markers in 4 cases of gonadoblastoma using immunostaining techniques. Our results showed that TSPY expression was closely associated with initiation and various stages of gonadoblastoma development. TSPY protein localized with established germ cell tumor markers, such as the placental alkaline phosphatase, c-KIT, and OCT3/4, in the same tumor cells of both gonadoblastoma and adjacent carcinoma in situ, the precursor for germ cell tumors. These findings support the candidacy of TSPY as the gene for the gonadoblastoma locus on Y chromosome and suggest that TSPY could be a significant marker for these types of germ cell tumors.

BACKGROUND Ovarian germ cell tumours (OGCTs) typically arise in young females and their pathogenesis remains poorly understood. We investigated the origin of malignant OGCTs and underlying molecular events in the development of the various histological subtypes of this neoplasia. RESULTS We examined in situ expression of stem cell-related (NANOG, OCT-3/4, KIT, AP-2gamma) and germ cell-specific proteins (MAGE-A4, NY-ESO-1, TSPY) using a tissue microarray consisting of 60 OGCT tissue samples and eight ovarian small cell carcinoma samples. Developmental pattern of expression of NANOG, TSPY, NY-ESO-1 and MAGE-A4 was determined in foetal ovaries (gestational weeks 13-40). The molecular genetic part of our study included search for the presence of Y-chromosome material by fluorescence in situ hybridisation (FISH), and mutational analysis of the KIT oncogene (exon 17, codon 816), which is often mutated in testicular GCTs, in a subset of tumour DNA samples. We detected a high expression of transcription factors related to the embryonic stem cell-like pluripotency and undifferentiated state in OGCTs, but not in small cell carcinomas, supporting the view that the latter do not arise from a germ cell progenitor. Bilateral OGCTs expressed more stem cell markers than unilateral cases. However, KIT was mutated in 5/13 unilateral dysgerminomas, whereas all bilateral dysgerminomas (n = 4) and all other histological types (n = 22) showed a wild type sequence. Furthermore, tissue from five phenotypic female patients harbouring combined dysgerminoma/gonadoblastoma expressed TSPY and contained Y-chromosome material as confirmed by FISH. CONCLUSION This study provides new data supporting two distinct but overlapping pathways in OGCT development; one involving spontaneous KIT mutation(s) leading to increased survival and proliferation of undifferentiated oogonia, the other related to presence of Y chromosome material and ensuing gonadal dysgenesis in phenotypic females.

Abstract
BACKGROUND Gonodoblastomas with ovarian germ cell tumors (OGCTs) other than dysgerminoma are very unusual. This is the first case report of a pure endodermal sinus tumor of the ovary with gonodoblastoma in a 46 XX, female. CASE A 19-year-old female was admitted to our hospital with an abdominal mass and pain. She had elevated levels of CA-125 and AFP. Fertility sparing surgery was undertaken and revealed a Stage IA endodermal sinus tumor and gonodoblastoma in the same ovary. The patient refused chemotherapy and was followed-up for six months without disease. CONCLUSION Gonodoblastomas may occur in conjunction with OGCTs. Tumor markers and immunohistochemical examination may help in the diagnosis of these OGCTs with gonodoblastoma.

Abstract
OBJECTIVE To investigate the importance of morphological scoring systems in differentiation of ovarian tumors in childhood. METHODS Morphological assessment using DePriest's index was performed for all patients with histopathological confirmation of ovarian tumor, with evaluation of tumor markers, from January 1997. RESULTS Fifty-three girls (age range 13 months to 19 years) were surgically treated for 59 ovarian tumors, including six bilateral. All lesions with cystic appearance on ultrasonography were benign, 23 of 35 semisolid, and four of ten solid tumors were also benign. Stage of malignant disease was as follows: stage I, ten; stage II, two; stage III, six. Sensitivity, positive predictive value and accuracy by DePriest's and Ueland's indexes for benign tumors (score <7) were: 0.88, 0.79; 0.89; and 0.94, 0.84; 0.93; respectively. Elevated levels of tumor markers were observed in 17 patients, including four patients with endocrine manifestations. In 24 patients ovaries were successfully preserved, including two patients with foci of immature teratoma in a dermoid cyst. CONCLUSION Ultrasonographic assessment with morphological analysis recommended by DePriest and Ueland is a very useful procedure for differentiating benign from malignant ovarian tumors in children. Tumor markers and endocrinological investigation are also useful for preoperative evaluation.

Abstract
PURPOSE The purpose of the study was to define the histological origin of gonadoblastomas, allowing the identification of high-risk patients. EXPERIMENTAL DESIGN Sixty paraffin-embedded gonadectomy or gonadal biopsy samples of 43 patients with gonadal dysgenesis were selected from our archives. We studied the morphology and immunohistochemical properties of the germ cells in 40 samples without neoplastic transformation and compared these findings with the morphological and immunohistochemical characteristics of 20 samples containing gonadoblastoma/dysgerminoma. RESULTS The overall incidence of germ cell tumors in our patient series was 35%. In dysgenetic gonads without germ cell neoplasia, besides the presence of areas with testicular and/or ovarian differentiation, areas of undifferentiated gonadal tissue were identified in 13 of 40 samples (32.5%). A subpopulation of germ cells within these undifferentiated areas stained positive for octamer binding transcription factor (OCT)3/4, the stem cell factor receptor, placental-like alkaline phosphatase, and testis-specific protein-Y encoded. Gonadoblastoma germ cells display identical staining results. Moreover, in gonads containing gonadoblastoma, adjacent to this lesion, areas of undifferentiated gonadal tissue with identical immunohistochemical characteristics were identified in 10 of 20 samples (50%). No adjacent tissue was available in five cases, whereas in the five remaining cases, it consisted of streak tissue. In three cases, an accumulation of OCT3/4-positive germ cells in the proximity of the malignant lesions was found, suggesting clonal expansion and final organization into gonadoblastoma nests. CONCLUSIONS Based on these observations, we hypothesize that gonadoblastomas originate from surviving OCT3/4-positive germ cells in areas of undifferentiated gonadal tissue within the dysgenetic gonad. Supportive evidence was obtained that carcinoma in situ arises in regions with testicular differentiation.

Abstract
Gonadoblastomas are rare germ cell and sex cord stromal tumours, often associated with dysgerminomas. They occur almost entirely in patients with pure or mixed gonadal dysgenesis and in male pseudohermaphroditism. A 19 year old female was admitted in our hospital for evaluation of primary amenorrhoea. She had poor secondary sexual characters, left sided streak gonad and right sided ovarian tumour. Histopathology showed gonadoblastoma in streak gonad with contralateral dysgerminoma. This case is presented because of its rarity and clinical importance of recognizing such cases because of excellent prognosis.

Abstract
Carcinoma in situ (CIS) is the precursor of malignant testicular germ cell tumors (GCTs) of adolescents and young adults, being the neoplastic counterpart of primordial germ cells/gonocytes. Carcinoma in situ cells will develop into invasive seminoma/nonseminoma. Gonadoblastoma (GB) is the precursor of invasive GCTs in dysgenetic gonads, predominantly dysgerminoma (DG). In this process, part of the Y chromosome (GBY region) is involved, for which TSPY is a candidate gene. A detailed immunohistochemical survey was performed for the known diagnostic markers, germ cell/placental alkaline phosphatase (PLAP), c-KIT, and OCT3/4, as well as testis-specific protein on the Y chromosome (TSPY) on a series of GBs, and adjacent invasive DGs. All 5 patients were XY individuals (4 females and 1 male). In contrast to c-KIT, PLAP was positive in all cases. The immature germ cells of GBs were positive for OCT3/4, whereas the mature germ cells were negative for this marker, but positive for TSPY. In every GB, a minor population of germ cells positive for both markers could be identified, similar to most CIS cells and early invasive DG. On progression to an invasive tumor, TSPY can be lost, a process that is also detectable in invasive testicular GCTs compared to CIS. These results indicate that GB is a heterogeneous mix of germ cells, in which the OCT3/4-positive cells have the potential to undergo progression to an invasive tumor. These early invasive stages are initially also positive for TSPY (like CIS), supporting a positive selection mechanism. Therefore, OCT3/4 in combination with TSPY is valuable to identify malignant germ cells in dysgenetic gonads. This could allow better prediction of the risk of progression to a GCT. In addition, the data support the model that GB represents the earliest accessible developmental stage of malignant GCTs.

Abstract
Gonadoblastomas are neoplasms of dysgenetic gonads which may undergo regression or become overgrown by malignant germ cell tumors (mGCTs). Since little is known about their relationship to normal gonadal development and mGCTs, we studied the phenotype and antigenic profile of gonadoblastomas in comparison with adjacent dysgerminomas and fetal gonads. Three cases of gonadoblastomas and fetal gonads of both sexes were analyzed using oncofetal markers to M2A-antigen (M2A), germ cell alkaline phosphatase (PLAP/GCAP), receptor tyrosine kinase c-kit (c-kit), and somatic angiotensin converting enzyme (sACE) as well as the proliferation marker MIB-1. Morphologically, microfollicular pattern of gonadoblastomas showed a fetal germ cell organization reminiscent of oocytic clusters of fetal ovaries. They contained both cell types, similar to oocytes (M2A-, GCAP-, c-kit+/-, sACE-) and oogonia (M2A+, GCAP+, c-kit+, sACE+). The percentage of germ cells immunoreactive for oncofetal markers and the proliferation index increased from microfollicular over coronary patterns to adjacent dysgerminomas. Supportive cells of gonadoblastomas showed a uniform phenotype (CK18+, vimentin+, sACE+, alpha-inhibin+, M2A-) but in contrast to fetal germ cells lacked a clear equivalence to fetal tissues. Our results show that gonadoblastomas mimic female fetal ovary and exhibit a stepwise progression from follicular pattern to coronary pattern and finally to dysgerminomas.

Abstract
Gonadoblastoma is an unusual mixed germ cell-sex cord-stromal tumor that has the potential for malignant transformation and 30% of all patients with gonadoblastoma develop germ cell tumors mainly dysgerminoma/seminoma. An additional 10% gives rise to other malignant germ cell neoplasms. This tumor affects a subset of patients with intersex disorders. The age at diagnosis is variable ranging from birth to the fourth decade, but around 94% of cases are diagnosed during the first three decades of life and there are few cases with gonadoblastoma diagnosed in infants. In this paper, we present the histological and molecular findings of four patients with gonadal dysgenesis who developed gonadoblastoma in the first 2 years of life and one case with bilateral dysgerminoma diagnosed at 15 years of age. The sex chromosomes of mosaic patients do not distribute homogenously in dysgenetic gonads; however, statistical analysis of FISH results revealed significant differences between the XY cell line in the gonadoblastoma compared with the dysgenetic testis. Our cases demonstrate that tumors could be present at a very early age, so the prophylactic removal of the gonads is advised.

Abstract
Cytogenetic analysis of a young woman with gonadal dysgenesis and bilateral gonadoblastoma shared a male karyotype with a rearranged Y chromosome, interpreted as a pericentric inversion. The breakpoints, defined by fluorescent in situ hybridization (FISH), were located on the very distal short arm on band Yp11.31 and in the middle of the Yq12 long arm heterochromatic region. FISH analysis documented that the short arm breakpoint was 93 Kb distal to SRY and disrupted the CD99 gene, which was transposed to the distal portion of Yq12. The proposita's phenotype was similar to that of XY individuals with gonadal dysgenesis but without signs of Ullrich-Turner syndrome. There were no mutations in the SRY gene. Cytogenetic analysis in the proposita's father showed mosaicism of a normal Y chromosome and several different rearrangements, such as deletion of a heterochromatin portion at band Yq12.2, a fragile site at the same band, structural rearrangements between the Y-chromosome and other autosomes, Y-chromosome aneuploidies, and "Premature Centromere Division" (PCD) anomaly. The proposita's inverted Y chromosome appears to have originated from paternal Y chromosome instability. The patient's female phenotype could be due to SRY CpG methylation-mediated positional effects (PEV).

Abstract
Gonadoblastoma is a rare tumor occurring almost exclusively in phenotypic females with intersex disorders and dysgenetic gonads. We report a case of gonadoblastoma in an 18-year old female who was admitted to our hospital for the investigation of primary amenorrhea. The patient underwent bilateral gonadectomy. A histopathologic study revealed streak gonads with extended calcification and bilateral gonadoblastoma. We describe the histopathologic features of gonadoblastoma and the pattern of its potential malignant transformation. Difficulties in the histological diagnosis of this rare tumor are also discussed. The need for early prophylactic removal of dysgenetic gonads, especially in patients that carry the Y chromosome, is emphasized.

Abstract
The prognosis and therapy for dysgerminomas are different from those of other ovarian tumor types, making accurate diagnosis imperative for patient care. OCT4 (POU5F1) is a transcription factor involved in the regulation of pluripotency during embryonic development. It can be detected in both pluripotent cells and other early germ cells. This study examines the expression of OCT4 in both dysgerminoma and nondysgerminomatous neoplasms involving the ovary. Formalin-fixed, paraffin-embedded cell blocks of 33 cases of dysgerminoma including 2 cases of gonadoblastoma associated with dysgerminoma and 3 cases of metastatic dysgerminoma, and 111 cases of nondysgerminomatous neoplasms involving the ovary were stained using the antibody against OCT4. All cases of dysgerminomas and gonadoblastomas were positive for OCT4 with strong nuclear staining. More than 90% of dysgerminoma cells in each case showed diffuse strong nuclear staining. In addition, 3 metastatic dysgerminomas also showed uniform strong nuclear staining. All nondysgerminomatous tumors (mature teratoma, 14; yolk sac tumor, 4; Sertoli-Leydig cell tumor, 15; granulosa cell tumor, 22; Brenner tumor, 3; carcinoid tumor, 4; struma ovarii, 2; fibroma, 5; thecoma, 1; serous adenocarcinoma, 5; endometrioid adenocarcinoma, 4; small cell carcinoma, 6; stromal sarcoma, 1; malignant lymphoma, 6; metastatic malignant melanoma, 1; metastatic carcinoid, 2; metastatic small cell carcinoma, 1; and metastatic lobular carcinoma of the breast, 1) were negative for OCT4, except for some cases of clear cell adenocarcinoma of the ovary. Four of 14 clear cell adenocarcinomas showed focal positive nuclear immunoreactivity for OCT4. OCT4 is a sensitive and relatively specific biomarker for the detection of dysgerminoma. It may also be useful in the diagnosis of gonadoblastoma, which contains similar cells and may be associated with dysgerminoma. OCT4 may aid in the detection of small foci of metastatic dygerminoma in extraovarian sites and may also help distinguish dysgerminoma from other primary and metastatic tumors of the ovary.

Abstract
Patients with dysgenetic gonads carry a high risk for the development of gonadal neoplasia. The aim of the study is to evaluate indications and feasibility of laparoscopy and video-assisted prophylactic gonadectomy in children with Ullrich Turner syndrome (UTS) or 46,XY gonadal dysgenesis (GoDy). Between 1996 and December 2002 five girls with UTS and nine patients with 46,XY GoDy (female gender role) were explored by laparoscopy. Video-assisted salpingo-oophorectomy or gonadectomy was performed using a three-port technique. Prophylactic salpingo-oophorectomy was exclusively performed in UTS patients with proven presence of translocated parts of the Y chromosome. In three patients with 46,XY GoDy laparoscopy was followed by surgical revision of the groin and open gonadectomy in four patients. In two cases with UTS the removed streak gonads contained small unilateral tumours stage pT1a, and in four cases of 46, XY GoDy histopathological investigation revealed bilateral neoplasms stage pT1b. We found the following tumour types: gonadoblastoma, dysgerminoma, testicular intraepithelial neoplasia, and mature teratoma. In conclusion, investigative laparoscopy gives a good image of the internal genital structures and allows the safe removal of the dysgenetic gonads during the same operation. The high rate of gonadal tumours underlines the indication for early gonadectomy in these patients.

Gonadoblastomas are rare mixed germ cell neoplasms, which are frequently diagnosed in testes excised for other reasons. In human patients these tumours are usually associated with undescended testes or dysgenetic gonads. This report describes a 10-year-old male dog with mixed gonadal dysgenesis ("streak testis" on the right side and testis on the left side) and bilateral gonadoblastomas. Immunohistochemical analysis revealed an atypical and mitotically active germ cell population which co-expressed placental alkaline phosphatase and c-kit oncogene, admixed with inhibin- and S-100 protein-positive sex cord cells. The findings were generally consistent with previous reports of the dual population of neoplastic cells in gonadoblastomas affecting human patients, and closely resembled the findings in the only other case reported in dogs. Moreover, the findings further support the proposal that gonadoblastomas should be considered a special form of in-situ germ cell neoplasia.

Abstract
OBJECTIVE Germ cell tumours are the most common ovarian tumours in childhood and adolescence. This diverse group of tumours derives from germ cells. DESIGN The aim of this work is presentation of germ cell tumours in the material from our clinic with characteristic clinical features, the scope of operation and effects of many years of observation. MATERIALS AND METHODS We treated 109 girls with germ cell tumours of the ovary: 13 had malignant tumours: there were 7 patients with dysgerminomas, 2 with endodermal sinus tumour of the ovary, 3 with immature teratomas, 1 with carcinoma embryonale. Gonadoblastomas was diagnosed 4 patients and mature teratomas in 92 patients. RESULTS 11 patient had gonadal dysgenesia with abnormal karyotype. These girls had no follicle apparatus in gonads and had elevated levels of gonadotropins. Gonadoblastoma is almost always found in patients with gonadal dysgenesis. Gonadoblastoma often produces estradiol or testosterone. There can be problems with diagnosis of the syndrome, because developmental features imitate the onset of normal puberty. Most patients with dysgerminoma have stage I of disease and surgery is sufficient. It must be suggested that patients of stage I who wish to preserve childbearing function may be treated with unilateral salpingoophorectomy and adjuvant chemotherapy. Monitoring of the treatment is connected with measurement of biochemical markers. Some of these markers are useful for monitoring of response to therapy. When levels of markers are low second look laparoscopic operation should be performed. Cytological smears and biopsy specimens from the remaining ovary, peritoneum and subdiaphragmatic area should be obtained laparoscopically. CONCLUSIONS The sift ultrasonographic investigations can be helpful in the early diagnosis of germ cell tumours of the ovary in girls. Absence of follicle apparatus in the gonads requires determination of levels of gonadotropins and karyotype. Fertility sparing operative treatment is preferred when karyotype is normal.

Abstract
Studies of distinct clinical prototypes have significantly contributed to our understanding of evolutionary abnormalities and their association with neoplasia. We describe a phenotypic female, aged 20 years at report, who was examined as an infant for developmental retardation. The clinical characteristics of the 9p- syndrome were present and the external genitalia were those of a normal female. The karyotype was 46XY,del(9)(p22). The parental karyotypes were normal. No SRY deletion or mutation was detected. Sonography showed the presence of a uterus. Basal luteinizing hormone values were normal; follicle stimulating hormone values were high (40 IU/L). Stimulation with human chorionic gonadotropin did not produce any rise in testosterone. The gonads were removed and histologic analysis disclosed dysgenetic gonads with gonadoblastoma in situ. This case constitutes the fourth case of gonadoblastoma developing in an individual with 9p- syndrome and sex reversal. This and analogous prototypes point to a locus (or loci) on the short arm of chromosome 9, which either constitutes a nonspecific suppressor gene or a gonadoblastoma suppressor gene. An alternative hypothesis would be that a gonad not normally differentiated is more prone to gonadoblastoma development without any specific gene involvement.

Abstract
A wide spectrum of phenotypic manifestations are seen in cases with 45X/46XY mosaicism. We present a case with 45X/46XY having female phenotype with Turner's stigmata. Prophylactic laparoscopic gonadectomy was performed and the patient was found to have mixed gonadal dysgenesis with bilateral gonadoblastomas. Microinvasive seminomas were also detected in both gonadoblastomas. The presence of Y cell line in karyotype prompted early and prophylactic gonadectomy, a procedure which is life-saving for these individuals.

Abstract
The study consisted of 46 intersexual patients who underwent gonadectomy at the age of 3 months to 19 years because of gonadal dysgenesis (GD; 40 cases) or true hermaphroditism (bisexual gonads; 6 cases). In patients with GD, the incidence of the 46,XY karyotype was 67.5%, whereas the remaining patients exhibited numerical and structural aberrations of sex chromosomes (NSASs), and all patients with bisexual gonads revealed NSAS. Seminoma was diagnosed in 1 patient with the 46,XY karyotype and pure GD (streak gonads). Intratubular carcinoma in situ (CIS) appeared as an exclusive lesion in 61.5% of 13 patients with mixed GD, in 54% of 11 patients with partial GD (bilateral testes), in 16.7% of 6 patients with bisexual gonads, and in none of 13 patients with pure GD. CIS also appeared in tubules in the vicinity of sex cord-derived tumors (gonadoblastoma nests and unclassified mixed germ cell-sex cord-stromal tumor; MGCSCST) and within the tumors. In 3 patients, gonadoblastoma replaced the whole bilateral gonads and is referred to as gonadoblastoma-only GD. The incidence of neoplastic lesions (mostly bilateral) was 90.9% in patients with partial GD, 76.9% (mostly unilateral) in patients with mixed GD, 23.1% (unilateral) in patients with pure GD, and 16.7% (unilateral) in patients with bisexual gonads. Disregarding types of disturbances of gonadal organogenesis, the incidence of lesions was 71.4% in 28 patients with the 46,XY karyotype and 35.3% in 17 patients with NSAS. We conclude, first, that NSAS is not a prerequisite for the appearance of GD and GD is more frequently associated with the 46,XY karyotype. Second, the spectrum of germ cell neoplastic lesions in GD is wider than reported. Besides germ cell carcinoma, CIS, and gonadoblastoma nests, the spectrum also includes a tumor of gonadoblastoma-only in cases of GD and MGCSCST. Third, the incidence of neoplastic lesions is related more to the severity of the disturbances of gonadal organogenesis than it is to aberrations in sex chromosomes. Fourth, less disturbed testicular organogenesis predisposes these patients more toward germ cell neoplastic lesions, which suggests that the testicular environment of a dysgenetic gonad plays an important role in germ cell neoplasia initiation, maintenance, or both.

Abstract
The Wilms' tumor gene (WT1) encodes a zinc-finger transcription factor involved in the development of the kidneys and gonads and their subsequent normal function. Mutations in the WT1 gene were identified in patients with WAGR (Wilms' tumor, aniridria, genitourinary abnormalities, and mental retardation), Denys-Drash syndrome, and Frasier syndrome (FS). Constitutional heterozygous mutations of the WT1 gene, almost all located at intron 9, are found in patients with FS. This syndrome is characterized by female external genitalia in 46,XY patients, late renal failure, streak gonads, and high risk of gonadoblastoma development. We report a male with FS with an unusual phenotype characterized by normal penis size with perineal hypospadias, end-stage renal failure at the age of 19 yr, normal adult male serum T levels, extremely elevated gonadotropin levels, para-testicular leiomyoma, unilateral testicular germ cell tumor, bilateral gonadoblastoma, and absence of gonadal dysgenesis. Automatic sequencing identified the IVS9 +4C>T mutation in the WT1 gene, which predicts a change in splice site utilization. WT1 transcript analysis showed reversal of the normal positive/negative KTS (lysine, threonine, and serine) isoform ratio, confirming the diagnosis of FS. This patient with FS presents an external genitalia of Denys-Drash syndrome, suggesting that these two syndromes are not distinct diseases but may represent two ends of a spectrum of disorders caused by alterations in WT1 gene. This case expands the spectrum of phenotypes associated with WT1 mutations, by including predominantly male ambiguous genitalia and absence of gonadal dysgenesis, extremely high gonadotropin levels, and delayed adrenarche, and presence of a para-testicular leiomyoma, bilateral gonadoblastoma, and germ cell neoplasia.
