Parasitic dermoid cyst managed laparoscopically in a 29-year-old woman: a case report.

Background: Dermoid cysts are one of the most frequently occurring ovarian cysts; parasitic dermoid cysts, however, are extremely rare.

Methods: We report a case of a 29-year-old Japanese woman with an incidental finding of an adnexal mass on bimanual examination. Sonographic imaging reported an 8 cm mass in the Pouch of Douglas. This was found to be a parasitic dermoid cyst and was removed at laparoscopy.

Conclusions: We believe laparoscopy to be a safe and effective means of managing parasitic ovarian dermoid cysts.
