Abstract
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.
