Presentation
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]

Increased Abdominal Girth
A case of gonadoblastoma with coexisting dysgerminoma developing in both ovaries of a 20-year-old girl who had increased abdominal girth is presented here. A pelvic mass measuring 20 x 14 cm was detected by pelvic ultrasonography. [ncbi.nlm.nih.gov]

Short Arm
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. [ncbi.nlm.nih.gov]

Suggestibility
The expression and molecular properties of TSPY suggest that it is the putative gene for the gonadoblastoma locus on Y chromosome. [ncbi.nlm.nih.gov]

Widely Spaced Nipples
46,XY gonadal dysgenesis was diagnosed in a 5.5-year-old phenotypically female patient who had physical and somatic stigmata of Turner syndrome such as webbed neck, low hairline, widely spaced nipples, cubitus valgus and coarctation of the aorta. [ncbi.nlm.nih.gov]

Neglect
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. [ncbi.nlm.nih.gov]
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. [research.manchester.ac.uk]

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
The vast majority are found associated with disorders of sexual development (previously known as "intersex disorders") often found during a workup for an newborn or infant with ambiguous genitalia may be hormonally active and present with precocious puberty [radiopaedia.org]
The background knowledge of the patient revealed that she had no uterus (based on the previous workup by a local clinician). [jhrsonline.org]
Further, no standard approach or guidelines have been established for the diagnostic workup and management of these patients. [ijpeonline.biomedcentral.com]
Treatment
Five years after treatment by surgery and irradiation the patients are well and free of recurrence. [ncbi.nlm.nih.gov]
Prognosis
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]
