Objective
Ovarian mature teratoma (OMT) is a common ovarian tumor found in the
pediatric population. In 10% to 20% of cases, OMT occurs as multiple
synchronous or metachronous lesions on ipsi- or contralateral ovaries.
Ovarian sparing surgery (OSS) is recommended to preserve fertility, but
total oophorectomy (TO) is still performed. This study reviews the
clinical data of patients with OMT, and analyzes risk factors for second
events.
