Teratoma is the most common type of germ cell tumor, which is better known as dermoid cyst. Dermoid cyst is the most common ovarian tumor in women in the second and third decades of life. Parasitic teratoma,which is autoamputation of an ovarian teratoma and reimplantation into a different place, is rare, and it is extremely rare if it is in the pouch of Douglas. Only a few cases have been found in this location so far. Here, the authors report an interesting case of parasitic teratoma. They draw the conclusion that if intraperitoneal teratoma is suspected in an imaging examination, surgeons should consider the possibility of adnexal autoamputation, including asymptomatic torsion.
