Abstract(s)

Dermoid ovarian cysts are the most common germ-cells tumours of the ovary, but strumal carcinoid transformation is rare. The authors report the case of an asymptomatic 20 year-old woman, referred to the gynaecological outpatient clinic, because of the ultrasound finding of an adnexal cyst. On physical examination a right adnexal mass was identified. A repeat ultrasound revealed an ovarian mass measuring 11.5cm, with characteristics that were suggestive of an ovarian teratoma. A CT-scan was performed that was also suggestive of this diagnosis. Tumoral markers were negative, except for CA19.9. The patient was submitted to laparoscopic right adnexectomy and histopathological examination revealed an ovarian bigerminal mature cystic teratoma with strumal carcinoid transformation, but no capsular invasion. Currently, 18 months after surgery the patient is pregnant and remains symptom free.
