ABSTRACT

Background: Malignant germ cell tumors of the ovary constitute a heterogeneous group of highly malignant and rapidly progressive neoplasms that usually appear during the first two decades of life. Its frequency in Mexico is 3.4% on ovarian tumors. Approximately 10% of affected patients report acute abdominal pain due to capsular distension, necrosis, hemorrhage, rupture or torsion.
Clinical Case: A 17 years-old patient, who went to the Emergency Department for pelvic pain of sudden onset. It was decided to perform a laparotomy and ovarian torsion was found secondary to a right adnexal tumor, so salpingo-ophorectomy was performed. High alpha-fetoprotein concentration (10.702 ng/mL) was detected; the Pediatric Oncology Service indicated chemotherapy for two years; however, after stopping the treatment, its concentration persisted. The ultrasound and PET-SCAN did not show active disease, so it was sent to the gynecological endoscopy service, where they performed diagnostic laparoscopy, observing multiple tumor implants. The histopathological results was endodermal sinus tumor. The patient was sent, again, to Pediatric Oncology to continue with chemotherapy and radiotherapy. It is currently stable, with a decrease in values of alpha-fetoprotein (last determination: 1200 ng/mL).
Conclusion: The importance of diagnostic laparoscopy is especially relevant in this type of cases when there is disagreement between biochemical and imaging studies (ultrasound and PET-SCAN), which through laparoscopy guides us towards a more accurate diagnosis through visualization and direct biopsy taking sample and give a directed management.
