Dermoid cysts are the most common germ cell tumors of the ovary in women of reproductive age. We report 67 cases of patients with dermoid cysts (mean age, 31.31 years) originating from the ovary treated from 1994 to 2006 at the Obstetrics and Gynecology Department of Aschaffenburg Hospital-Clinic in Germany. Most patients (60) underwent cyst removal. In two patients salpingooophorectomy was performed and in five partial oophorectomy was performed. Additional surgery ensuing laparotomy was never necessary. None of the patients had long-term postoperative complications. Two patients were at nine and 15 weeks of gestation and postoperatively were well following termination of pregnancy. In a group of 43 women, who desired pregnancy, 37 pregnancies resulted. The overall intrauterine pregnancy rate was 83.7%; one patient had an ectopic pregnancy (2.32%). To receive more information on this disease, treatment should be performed according to international protocols.
