Overview
The prevalence of gonadoblastoma varied depend on the chromosomal content, presence or absence of mosaicism, gonadal histology and age of the patient between 15% to 30%. The incidence of gonadoblastoma varied according to the presence or absence of Y chromosomal content and age of the individual. Patients with Turner syndrome who have Y chromosomal content either completely or partially can develop gonadoblastoma with an incidence as high as 43%. Phenotypical female with XY gonadal abnormalities have been observed to develop gonadoblastoma by 40%. Gonadoblastoma can be found in any age, but it is more common to present before the age 15. Since it usually affects individuals with gonadal dysgenesis, there is no genotype-phenotype correlation. Phenotypically, it tends to affect female individuals at a greater extent.
Epidemiology and Demographics
Incidence
- The incidence of gonadoblastoma varied according to the presence or absence of Y chromosomal content and age of the individual.[1][2]
- Phenotypical female with XY gonadal abnormalities have been observed to develop gonadoblastoma by 40%.
- Patients with Turner syndrome who have Y chromosomal content either completely or partially can develop gonadoblastoma with an incidence as high as 43%.
Prevalence
- The prevalence of gonadoblastoma varied depend on the chromosomal content, presence or absence of mosaicism, gonadal histology and age of the patient between 15% to 30%.[3]
Age
- Gonadoblastoma affects individuals of any age but tends to present at a greater extent prior to 15 years of age.[4]
Race
- There is no racial predilection to gonadoblastoma.
Gender
- It commonly originated from dysgenetic gonad but has been observed in women with normal ovary and karyotypes, although rarely.[4][5]
- Since this tumor affects gonads, there is no genotype-phenotype correlations.
- The majority of affected individuals appear phenotypically female, but in reality, they are intersex.
- Although very uncommon, there are reports of gonadoblastoma development in phenotypically and genotypically normal men.
