Abstract
BACKGROUND: Disorders of sex development are congenital conditions with atypical chromosomal, gonadal, or anatomical sex development. Gonadal dysgenesis in patients containing a Y chromosome have a high risk of developing germ cell tumors with potential for malignant transformation. CASE: We present the case of a 17-year-old phenotypic female with primary amenorrhea and 46,XY complete gonadal dysgenesis. Pelvic ultrasound showed a solid cystic lesion in the right gonad. Pathology showed a gonadoblastoma-associated mixed gonadal germ cell tumor with dysgerminoma and hepatoid yolk sac tumor. SUMMARY AND CONCLUSION: To our knowledge, this mixed neoplasm association has not been previously reported and this case illustrates the challenges for the diagnosis of gonadal dysgenesis-associated tumors, emphasizing its recognition and prognostic implications.
