Abstract

Parasitic dermoid cysts may form from autoamputation of the ovarian mass secondary to torsion or rupture. It may then reimplant in surrounding structures and undergo subsequent neovascularization and further growth. The true incidence of these cases is unknown, however, a study reported a 0.04% incidence among 1,007 cases of dermoid cysts. This report describes the case of a 30-year-old multigravida who presented with an ultrasound finding of an ovarian dermoid cyst, which, upon laparoscopic surgery, turned out to be a parasitic dermoid cyst adherent to the bladder, with grossly normal bilateral ovaries. Theories on the development of parasitic dermoid cyst are also presented.
