OVARIAN DERMOID CYST

Abstract

Objective: 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 years-old woman 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. Conclusion: Infection of a mature teratoma is a relatively uncommon event. However, based on our case and others, superinfection with abscess formation should be considered in the differential diagnosis whenever a patient with a documented pelvic mass and fever.
