Abstract
We present a 18 year old phenotypic female patient who presented for primary amenorrhea. Pelvic ultrasound revealed a hypoplastic uterus and CT scan showed a hypoplastic right gonad and a left gonadal tumor with extrapelvic location. Karyotype was 46XY. Hormonal assessment indicated hypergonadotropic hypogonadism: FSH was 39.69 mUI/ml, estradiol was 28.07 pg/ml, testosterone was 0.17 ng/ml. DHEA level was high – 21 ng/ml. Gonadectomy was performed at 15 years and histologic examination diagnosed left gonadoblastoma and right teratoma in a dysgenetic gonad. The patient had a good postoperatory evolution. Menses were induced with estrogenic and then estroprogestogenic treatment. Plastic breast surgery was performed at 18 years. Establishing the genotypic sex in patients with primary amenorrhea represents a crucial step knowing that intersex disorders bearing Y chromosomal material have a high risk for gonadoblastoma and germ cell tumors.
