Dysgerminoma and ovarian gonadoblastoma in Swyer syndrome

XY karyotype and poor secondary sexual character and normal external genitalia. She suffered of abdominal pain. In palpation of the ab-domen, an irregular mobile mass was detected in left lower quadrant. The ultrasound revealed uterine size approximate dimensions 3×2 cm (infantile) and a 19 cm pelvic mass heterogeneous and multi-loculated in left side of the pelvic cavity with possible origin of the left ovary. In addition, in right pelvic fossa, a mass about 6 cm was detected. CT-Scan showed a pelvic mass with overall dimensions of 10 cm with vicinity to the left iliac vessels, modest amounts of ascities along with evidence of peritoneal dis-semination (seeding). In laparotomy we observed massive ascities and a 20 cm solid mass in left ovary and a small mass in right ovary and involvement para aortic lymph node. Pathological report indicated as stage III of dysgerminoma in left ovary and gonadoblastom in right ovary. Conclusion: This case is presented because it could have excellent prognosis if not missed opportunities of early recognizing and furthermore adequate treatment with gonadectomy. Abstract
