Résumé
The authors present the clinical history of a 15-year-old young woman, student, from David, Chiriquí, who complained of menstrual irregularities associated with the sensation of a mass in the right iliac fossa. Exploratory laparotomy revealed a right ovarian tumor, which was totally resected. The histopathological examination showed an endodermal sinus tumor, stage one, in the right ovary. The patient received four cycles of cytotoxic i.v. therapy every 3 weeks, after surgery, with vinblastine 6 mg/m2 body surface (B.S.) on days 1 and 2, bleomycin 15 u daily for 5 days, cisplatin 20 mg/m2 B.S. daily for 5 days, plus hydration with normal saline (5 to 6 l/day). Follow up studies with abdominal and pelvic sonograms, chest x-ray, feto protein and physical examination have not shown evidence of tumor activity 36 months after diagnosis
