ABSTRACT
A case is presented in which a preoperatively diagnosed hydatid cyst was found to be a mature cystic teratoma on pathological examination. Diagnostic dilemmas surrounding each disease are discussed.

We report a case of a 34-year-old woman who underwent laparoscopy for her adnexal tumor. Coexistence of ovarian mucinous cystadenoma and parasitic ovarian teratoma of the omentum was found and successfully treated by laparoscopic surgery. As our case presented, it is thought that the omental teratomas could be resulting from the auto-amputation and re-implantation of a dermoid cyst of the ovary.

Extragonadal mature cystic teratomas (dermoid cysts) have been reported occasionally, with the most common site being the omentum. We report a rare case of a parasitic dermoid cyst that was incidentally found in an indirect inguinal hernia sac in a 66-year-old woman. The right ovary was absent from its proper anatomical location. Histopathologic study revealed a mature cystic teratoma with viable ovarian tissue. These findings suggested auto-amputation of the ovary either by inflammation or torsion.
