Ovarian-sparing surgery for ovarian teratoma in children.

Background: Ovarian teratoma (OT) is the most common ovarian neoplasm in children. Oophorectomy has been the standard treatment but may impair fertility. The aim of this study was to investigate the feasibility and outcome of ovarian-sparing surgery (OSS) for OT.

Mucinous cystadenoma arising 3 years after ovarian-sparing surgery for mature teratoma in a child.

We report the case of a 15-year-old girl diagnosed with mucinous cystadenoma 3 years after ovarian-sparing surgery for a mature teratoma located in the same ovary. Ovarian teratoma is the most common ovarian neoplasm in children, whereas mucinous cystadenoma is extremely rare during childhood.
