Abstract
Gonadoblastoma is a rare ovarian tumor composed of sex cord cells and primitive germ cells. While the majority of gonadoblastomas are found in individuals with 46,XY gonadal dysgenesis, they are also rarely seen in patients with a 46,XX karyotype. We report a case of a fourteen-year-and-six-month-old girl presenting with an uncommon cause of virilization due to a virilizing ovarian tumor. The patient underwent bilateral salpingo-oophorectomy. Upon histopathological examination, the excised tumor was confirmed to be bilateral gonadoblastoma, with dysgerminoma on the left side. Malignant gonadal tumors should be considered in cases of primary gonadal insufficiency with a 46,XX karyotype and progressive virilization. Even when laboratory and imaging tests show no abnormalities, a gonadal biopsy should be considered.
