Presentation
Background: Ovotesticular disorder of sexual development (DSD is a rare form of DSD in which both testicular and ovarian tissues are present in the same individual either in a single gonad (ovotestis) or in opposite gonads with a testis and an ovary on [abstracts.eurospe.org]
Case 2 A 19-year-old patient with female phenotype presented with primary amenorrhea. Ultrasono-graphy indicated uterine agenesis, and showed a 12 mm simple cyst on the right gonad. [ams.ac.ir]
The present observations suggest that TSPY may either be involved in the oncogenesis of or be a useful marker for both types of germ cell tumors. [scholars.northwestern.edu]
Most cases develop in women who have an abnormal karyotype in which at least a portion of the centromeric region of the short arm of chromosome Y is present, a region often referred to as the GBY locus. [ncbi.nlm.nih.gov]
In the present case, the patient received bilateral gonadectomy. [spandidos-publications.com]

Urogenital
- Amenorrhea
Case 2 was a 15-year-old female presented with lack of pubertal development and primary amenorrhea. Physical examination revealed short stature (−2.1 SDS), Tanner stage I breast development, normal female external genitalia phenotype. [abstracts.eurospe.org]
Case 2 A 19-year-old patient with female phenotype presented with primary amenorrhea. Ultrasono-graphy indicated uterine agenesis, and showed a 12 mm simple cyst on the right gonad. [ams.ac.ir]
At the age of 17 years, the patient presented primary amenorrhea and was referred to our department. Physical examination was consistent with Tanner 1 development and external genitalia were female phenotype. [ncbi.nlm.nih.gov]
- Cryptorchidism
WT1 gene mutations have been described in 46,XY patients with ambiguous genitalia or complete gonadal dysgenesis with or without Wilms' tumor, nephropathy, gonadoblastoma, and other defects, e.g., cryptorchidism or hypospadias. p.R462W is a hot spot mutation [ncbi.nlm.nih.gov]
The following factors may raise a child’s risk of developing an extracranial, gonadal germ cell tumor: Cryptorchidism. If a boy has an undescended testicle, he has a higher risk of developing a testicular seminoma tumor. [cancer.net]
Macroscopy Usually small Often impossible to determine nature of gonad bearing tumor sometimes identified as: a streak gonad (many become apparent only on microscopic examination) cryptorchid testis never a normal ovary ≈36% bilateral The gross appearance [humpath.com]
The gonadal phenotype ranges from complete gonadal dysgenesis, or ovotestes, to cryptorchidism or hypospadias [ 7 ]. The patient in our study presented complete 46,XY gonadal dysgenesis caused by partial 9p monosomy. [omicsonline.org]
He has two sons, who both presented with bilateral cryptorchid testis, which is one of the major risk factors for testicular GCC [46]. [journals.plos.org]
- Secondary Amenorrhea
A 28-year-old woman with well-developed female secondary sexual characteristics, secondary amenorrhea, short stature and a few somatic anomalies of streak gonad syndrome who had bilateral 'burnt out' gonadoblastoma associated with 45,X karyotype is reported [ncbi.nlm.nih.gov]

Workup
May occur in phenotypic males or females. associated with disorders of sexual development (previously known as "intersex disorders") often found during a workup for a newborn or infant with ambiguous genitalia may be hormonally active and present with [radiopaedia.org]
However, any individual with sex organ maldevelopment disorder is suspected of having gonadoblastoma and should be considered for a complete workup to diagnose the underlying disorder and should also be monitored by imaging studies for the presence or [wikidoc.org]
[…] histopathologic features with data from ancillary techniques such as immunohistochemistry and cytogenetics and discussions of the relevant clinical manifestations of gynecological diseases to provide you with the necessary tools to make a comprehensive diagnostic workup [books.google.ro]
The background knowledge of the patient revealed that she had no uterus (based on the previous workup by a local clinician). [jhrsonline.org]
Workup Laboratory Studies Chromosome analysis Chromosome analysis is the most important laboratory study in the diagnosis of gonadoblastoma. The karyotype at birth is used as a screening test in neonates with abnormal genitalia. [emedicine.medscape.com]
Treatment
Treatment Options Surgical removal of the tumor is the mainstay of the treatment. Surgical removal of the affected gonad must be considered in case of coexisting sex development disorders. [wikidoc.org]
Five years after treatment by surgery and irradiation the patients are well and free of recurrence. [ncbi.nlm.nih.gov]
Prognosis
Patients with a pure gonado-blastoma have an excellent prognosis provided both gonads are excised. [ams.ac.ir]
Furthermore, the prognosis for gonadoblastoma accompanied by germ cell tumors other than dysgerminoma was very poor in the past, but the patient remains well 25 months after the first operation. [ncbi.nlm.nih.gov]
Etiology
The contribution of specific genes on the Y chromosome in the etiology of prostate cancer has been undefined. [ncbi.nlm.nih.gov]
It is expressed in the germ cells of DSD-XY patients with distinct etiologies but also in foetal and pre-meiotic male spermatogonia. However, the GBY region extends to proximal Yq11 and therefore includes probably more than one candidate gene. [pubmed.ncbi.nlm.nih.gov]
ARTICLES Hypothesis: a Y-chromosomal gene causes gonadoblastoma in dysgenetic gonads Development 1987 101: 151-155; Summary The role of the human Y chromosome in the etiology of gonadoblastoma, a gonadal neoplasm, is considered and a two-part model is [dev.biologists.org]
