Gonadoblastoma Associated With Malignant Teratoma
Southern Medical Journal, 1979A case of gonadoblastoma associated with malignant teratoma in the contralateral ovary is described. Considerations are offered concerning the malignant potential of dysgenetic gonads as well as the diagnostic and therapeutic approaches in such situations.

Gonadoblastoma. Immunohistochemical and Ultrastructural Observations
International Journal of Gynecological Pathology, 1989Gonadoblastoma is an unusual tumor that typically arises in a streak gonad or an abnormal testis of an individual having a Y chromosome. It is a mixed tumor composed of primitive germ cells and sex cord cells arranged in characteristic nests containing hyaline material.

Gonadoblastoma: an unusual ovarian tumor
Annals of Diagnostic Pathology, 2010Gonadoblastomas are unusual benign neoplasias that frequently appear in the dysgenetic gonads of women with chromosome Y anomaly. In this study, we reviewed 3 gonadoblastoma cases, 2 of which were bilateral, in patients 21, 17, and 18 years of age. Two of them presented 46 XY karyotype and gonadal dysgenesis, whereas the third presented 46 XX karyotype.

Gonadoblastoma: Structures and background of development
American Journal of Obstetrics and Gynecology, 1983Based on earlier studies relative to development and maturation of human gonads, a hypothesis is presented, namely, that the production of "psammoma bodies" in gonadoblastoma, as well as intensification of calcification and hyalinization processes, may be an expression of recapitulation of the involution phase of the indifferent gonad and the terminal ...

Gonadoblastoma in a patient with gonadal dysgenesis
American Journal of Obstetrics and Gynecology, 1965Abstract 1.1. A case is presented of gonadal dysgenesis in a phenotypical femal with XY chromosome structure with the development of an ovarian tumor containing the basic primitive cell types conforming to the criteria for gonadoblastomas. 2.2.

Ultrastructure of gonadoblastoma.
Archives of pathology, 1975We examined, ultrastructurally, gonadoblastomas from two phenotypic females with a 46,XY and 46,XY/45, XO genotype, respectively. Ultrastructurally, germ cells of gonadoblastoma resembled immature gonocytes; it was not possible to classify them into exact developmental stages given for normal fetal testes or ovaries. In the dysgerminomatous part of the
