Malignant mixed ovarian germ cell tumor with embryonal component.

Area of Science:

• Gynecologic Oncology
• Reproductive Endocrinology
• Pediatric Oncology

Background:

• Malignant germ cell tumors (GCTs) of the ovary are rare, comprising <10% of ovarian cancers.
• These tumors predominantly affect adolescent and young women, highlighting the critical need for fertility-sparing management.
• GCTs are classified into dysgerminomas and non-dysgerminomas, with yolk sac tumors and immature teratomas being common non-dysgerminomas.

Observation:

• A 19-year-old female presented with abdominal pain and massive ascites.
• Diagnostic workup revealed a malignant mixed ovarian germ cell tumor.
• The tumor had a significant embryonal carcinoma component.

Findings:

• The patient was treated with surgical resection and chemotherapy.
• Embryonal carcinomas, while rare, represent a highly malignant ovarian cancer subtype.
• Successful management necessitates careful consideration of fertility-sparing surgical approaches.

Implications:

• Fertility-sparing techniques and appropriate chemotherapy are crucial for managing ovarian GCTs in young patients.
• The majority of patients can retain ovarian function and reproductive capacity post-treatment.
• Early diagnosis and tailored management strategies are key to optimizing outcomes for adolescent and young women with ovarian GCTs.
