How do dermoid cysts look?

Dermoid cysts look like tumors with hair, teeth, bones and even eyes, says MedicineNet. This is because a dermoid cyst springs from a totipotential germ cell in a woman's ovary. These cells can mature into many types of cells.

Dermoid cysts are also called teratomas, says MedicineNet. They usually occurring during a woman's reproductive years. They can be as small as half an inch and as large as 17 inches in diameter. Large cysts increase the risk of torsion and rupture, and doctors recommend that they be removed. They can be removed laparoscopically or through an open surgery.

Though the great majority of dermoid cysts are benign, a small percentage become malignant, states MedicineNet.
