RESUMO
The mature cystic teratoma of the ovary (ovarian dermoid cyst) is the most common ovarian neoplasm in young women and comprises approximately 10~25% of all ovarian tumors. There are many complications such as torsion, rupture, infection, suppuration, and rarely malignancy change. Teratoma derives from the three embryonic cell lines and may contain skin, sebaceous tissue, hair, cartilage and bone, neuroglial tissue, gastrointestinal and respiratory tissue, teeth, and muscle. Even though the presence of dental tissue within dermoid cysts has been reported in the literature, the cysts containing jaw bone and teeth are extremely rare. We report a case of ruptured ovarian dermoid cyst containing jaw bones and eight well-formed teeth with a brief review of literature.
