Benign Ovarian Dermoid Cyst Complicated with Infection in Post Menopausal Woman: An Unusual Case

Mature teratoma is the most common germ cell tumor(and the most common tumor) of the ovary,composing more than 20% of all ovarian neoplasms. Super infection of dermoid ovarian cyst is very rare.Case Report: A 72 year-old woman was admitted to the gynecological outpatient clinic because of lower abdominal pain and fever. Gynecological examination and ultrasonography revealed a heterogeneous cystic mass in the right ovary. Abdominopelvic CT scan revealed a right ovarian mass (15×15 cm) thought to be a dermoid cyst. Right adnexectomy was performed. The pathological evaluation suggested infected benign ovarian dermoid. They are the most common ovarian neoplasm found in adolescence and during pregnancy. Mature cystic teratoma may be complicated by torsion, rupture, and malignant change infection of a mature teratoma is a relatively uncommon event. However, based on our case and other cases, superinfection with abscess formation should be considered in the differential diagnosis whenever a patient with a documented pelvic mass and fever refers to gynecologists.
