Gonadoblastoma: an unusual ovarian tumor.

Gonadoblastomas 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.
