Dermoid cysts, also known as mature cystic teratomas, are the commonest ovarian tumor. They occur primarily in the reproductive years, but can also occur in children. The tumor has all three germ layers that are seen in the body - ectoderm, mesoderm and endoderm. As such, the tumor has fat, hair and teeth in it. Teratomas sometimes can be very organized and appear to form fetal-like tissues. Dermoids are bilateral 15-20 percent of the time. Treatment is surgical removal prior to torsion or rupture.
