The development of a somatic neoplasm within an ovarian dermoid cyst (mature cystic teratoma) is a rare, but well described, phenomenon which occurs in approximately 1% of all cases. Any of the tissue components of a dermoid cyst has the potential to undergo neoplastic transformation with carcinoid tumors and squamous cell carcinomas being among the most common neoplasms. We report a case of a ganglioneuroblastoma arising within an ovarian dermoid cyst, an association which, as far as we are aware, has not been described previously. Read More
