A gonadoblastoma is a complex neoplasm composed of a mixture of gonadal elements, such as large primordial germ cells, immature Sertoli cells or granulosa cells of the sex cord, and gonadal stromal cells.

Associations

Gonadoblastoma is most often associated with abnormal chromosomal karyotype, gonadal dysgenesis, and the presence of a Y chromosome.

It has been found in association with Turner's syndrome.^[1][2]

Classification

Main article: Germ cell tumor

Gonadoblastoma is classified as a germ cell tumor.^{[citation needed]}

Formerly, gonadoblastoma was sometimes regarded as a subset of dysgerminoma. In modern literature, it is sometimes considered to progress to dysgerminoma.^[3]
