MADRIGAL URENA, Angélica  and  MORA ROSENKRANZ, Brian. Ovarian immature (malignant) teratoma. Med. leg. Costa Rica [online]. 2018, vol.35, n.1, pp.146-151. ISSN 2215-5287.

The immature teratoma was first described in 1960 and cay be pure or mixed with a mature component. It is the second most common malignant germ cell neoplasm of all ovarian cancers (representing <1%). About 50% of pure immature teratomas of the ovary occur in women between the ages of 10 and 20 years. Treatment should be considered to preserve future fertility because the majority of ovarian germ cell tumors are curable with conservative surgery and combined combination chemotherapy. Most patients diagnosed with an immature teratoma are cured of their disease. However, in all patients, we recommend close follow-up, particularly in the first 2 years after diagnosis, where there is a greater chance of recurrence.

Keywords : Immature ovarian teratoma; paraneoplastic encephalitis; OCT4; fertility-preserving surgery.
