Objective: Benign mature teratoma during pregnancy is common, mostly discovered incidentally by antenatal sonography. However, repeated pregnancy coincident with ovarian mature teratoma is rarely reported. The cases of teratoma with rapid growing characteristics are even more unique.

Case Report: A 17-year-old woman was pregnant at 6 weeks of gestation with a left ovarian teratoma. She underwent artificial abortion followed by surgical removal of the teratoma. However, eleven years after the surgery, a right ovarian teratoma was found incidentally by antepartum sonography at 21 weeks of gestation. The right ovarian teratoma developed uneventfully, with rapid growth during pregnancy. Abdominal delivery at term was accomplished without any complication.

Conclusion: Younger patients and patients with bilateral or large size dermoid cysts should be followed up closely. Further studies are needed for better understanding of its natural clinical course and the mechanism of progression. The treatment options should be made individually, weighing the risks of torsion, rupture, or obstruction of labor versus the potential for unnecessary surgical risk to mother and fetus.
